Two slim wristbands dominate the mid-range fitness tracker conversation: the Fitbit Charge 6 and the Garmin vivosmart 5. They cost roughly the same, look nearly identical on the wrist, and both count your steps, track your sleep, and record your workouts. That similarity is exactly why the comparison matters — you are not choosing between a budget band and a premium watch, you are choosing between two philosophies of what a fitness tracker should be.

The core difference: Fitbit has pushed the Charge 6 toward being a miniature smartwatch, with Google Wallet payments, Google Maps integration, YouTube Music controls, and a color touchscreen with double-tap gestures. Garmin has kept the vivosmart 5 focused on health and activity data, with a battery that lasts up to a week and training metrics that plug into Garmin’s broader ecosystem. Neither approach is objectively better — but one of them will fit your daily habits far better than the other.
If you live in the Google ecosystem and want notifications, payments, and music controls on your wrist without wearing a full smartwatch, the Charge 6 is the stronger pick. If you mostly want reliable tracking with minimal charging hassle and room to grow into more serious training tools, the vivosmart 5 makes more sense. This guide breaks down where each wins, where each falls short, and who should buy which.

Smartwatch with 1.83-Inch HD Touchscreen, Bluetooth Calling, IP68 Water Resistance, and 140+ Sport Modes
This is the most complete package of the three, and it earns the top spot precisely because it refuses to choose between fitness tracking and smartwatch convenience. The 1.83-inch IPS touchscreen is by far the largest display in this lineup — nearly 70 percent bigger than the AMOLED tracker’s screen — which makes workout data, notifications, and call controls genuinely readable at a glance. The standout feature is Bluetooth calling: neither the ENGERWALL S5 nor the AMOLED tracker lets you answer calls from your wrist, and that alone justifies the larger case for buyers who want to leave their phone in a bag during workouts.The 140+ sport modes dwarf the 16 modes on the ENGERWALL and the 25 on the AMOLED model, which matters if your routine mixes gym work, running, cycling, and more niche activities. Health tracking covers the expected heart rate, sleep, steps, breath rate, calories, and distance. The tradeoffs are real, though: you cannot reply to messages from the watch, GPS is connected-only through your phone, and the 5–7 day battery claim shrinks quickly if you take frequent calls or keep the display active. Compared with the slimmer picks, the bigger case is also noticeably less comfortable for overnight sleep tracking. Still, for a buyer who wants one device that does everything reasonably well, this model makes the most sense.
Pros:
- Bluetooth calling and full notification support directly from the wrist
- 140+ sport modes — far more than either competitor in this lineup
- Large 1.83-inch display that is easy to read mid-workout
- Broad health tracking including heart rate, sleep, breath rate, and distance
Cons:
- Messages cannot be answered from the watch
- GPS requires a connected smartphone
- Bulky for overnight wear, and real-world battery life drops with heavy calling
Best for: Buyers who want a single device that combines serious fitness tracking with smartwatch features like wrist calls and notifications.
Not ideal for: People who mainly want a discreet, sleep-friendly band, or athletes who need built-in GPS for phone-free runs.
Bottom line: The most versatile tracker of the three — pick it if you want fitness data and smartwatch convenience in one device.
“The most versatile tracker of the three — pick it if you want fitness data and smartwatch convenience in one device.”
ENGERWALL S5 Fitness Tracker with Heart Rate and Sleep Monitoring
Where the top pick goes big, the ENGERWALL S5 goes slim — and that is exactly its strength. This option stands out for sensory breadth in a budget band: alongside the usual heart rate, sleep, and activity tracking, it monitors blood oxygen, blood pressure, and body temperature, a combination neither competitor offers. That makes it better suited to buyers doing general wellness monitoring rather than sport-specific training, especially anyone who wants to spot trends in temperature or oxygen levels over time. Note that blood pressure tracking must be manually enabled in the Runmefit app before it appears, which trips up some first-time users.Compared with the AMOLED tracker, the S5 has a smaller, less vibrant display and fewer sport modes (16 versus 25), but its built-in USB connector means you never hunt for a proprietary charging cable — a small convenience that matters more than you’d expect. Its slim profile is the most sleep-friendly of the three, edging out the bulky 1.83-inch smartwatch for overnight comfort. The honest limitations: it shares the IP68 rating but is explicitly not suitable for hot baths, saunas, or prolonged soaking, and its 5–7 day battery sits at the shorter end of this group. For the price of admission, however, this pick makes the most sense for value-focused buyers who prioritize health metrics over smart features.
Pros:
- Unusually broad health monitoring: heart rate, sleep, SpO2, blood pressure, and body temperature
- Slim, lightweight design that is comfortable for overnight sleep tracking
- Built-in USB connector — no proprietary charger to lose
- Call, message, alarm, and reminder notifications included
Cons:
- Not suitable for hot baths, saunas, or prolonged soaking despite the IP68 rating
- Blood pressure monitoring must be enabled in the app before use
- Smaller, duller display and fewer sport modes than either competitor
Best for: Budget-conscious buyers who want the widest range of health sensors in a slim, sleep-friendly band.
Not ideal for: Users who want a rich display, wrist calling, or deep sport-specific tracking.
Bottom line: The best value here — a slim band that tracks more health metrics than pricier-looking rivals.
“The best value here — a slim band that tracks more health metrics than pricier-looking rivals.”
Fitness Tracker with 1.10-Inch AMOLED Display, Heart Rate and Sleep Tracking
This tracker occupies the sweet spot between the other two: more refined than the ENGERWALL S5, less bulky than the 1.83-inch smartwatch. Its defining feature is the 1.10-inch AMOLED touchscreen, which delivers deeper blacks, richer colors, and sharper readability in bright sunlight than either competitor’s LCD-based screen. If you check your stats dozens of times a day, display quality quietly becomes the feature you notice most, and this model wins that comparison decisively. Customizable watch faces let you tailor the home screen to show exactly the metrics you care about.Feature-wise, it sits sensibly in the middle: 25 sport modes is fewer than the smartwatch’s 140+ but covers the activities most people actually do, and 24/7 heart rate tracking plus sleep monitoring match the core offering of the other picks. Its up to 7 days of battery life is the best claimed runtime of the three in daily use, with 15 days of standby. Thoughtful extras — hydration and sedentary reminders, female health tracking, weather, and remote camera control — round out a package that feels considered rather than feature-stuffed. The caveats mirror the category: health measurements are for reference only, not medical advice, and GPS is connected-only. Compared with the S5, you give up temperature and blood pressure sensing; compared with the smartwatch, you lose calling. What you get in return is the best-balanced wearable of the group.
Pros:
- AMOLED display that is sharper and more sunlight-readable than either competitor
- Best claimed daily battery life of the three: up to 7 days
- 24/7 heart rate and sleep tracking across 25 sport modes
- Useful extras: hydration and sedentary reminders, female health tracking, remote camera control
Cons:
- Health measurements are for wellness reference only, not medical use
- Connected GPS requires a paired phone
- No wrist calling, unlike the top pick
Best for: Buyers who want a comfortable, everyday band with the sharpest display and longest daily battery in this lineup.
Not ideal for: Anyone who needs wrist calling or advanced health sensors like temperature and blood pressure tracking.
Bottom line: The best-balanced tracker here — a compact band with the group’s finest display and strongest battery claims.

Key Differences
The first real fork in the road is GPS. The Charge 6 has a built-in GPS receiver, so you can leave your phone at home for a run and still get an accurate route and pace. The vivosmart 5 only has connected GPS — it borrows your phone’s signal. For runners, walkers, and cyclists who sometimes go phone-free, this alone can decide the purchase. For gym-goers and indoor exercisers, the gap barely matters, since neither band needs GPS on a treadmill.
The second fork is ecosystem direction. Fitbit (now owned by Google) is converging toward a smartwatch-lite experience: tap-to-pay, turn-by-turn map mirroring, music controls, and a slick app that is easy to read at a glance. The catch is that many of its best insights — Daily Readiness, detailed sleep analytics, long-term trends — sit behind the Fitbit Premium subscription. Garmin’s app is less elegant but everything is free, and the data skews athletic: VO2 max estimates, training load, Body Battery energy tracking. If you see yourself eventually buying a running watch, the vivosmart 5 teaches you Garmin’s language early.
Third, battery behavior diverges in practice. Both claim up to seven days, but the Charge 6’s brighter, more interactive display and GPS use drain it faster in real conditions — expect four to five days. The vivosmart 5 routinely hits six to seven. That difference changes how the device feels to own: a band you charge twice a month fades into the background; one you charge weekly becomes another device on your mental checklist.
Detailed Comparison
Design and display (Fitbit Charge 6 wins — minor)
Both are slim bands with narrow touchscreens, but the Charge 6 is the more refined object. Its AMOLED panel is brighter and more colorful, and the double-tap gesture — tap thumb and finger together to dismiss alarms or answer calls — is genuinely useful mid-workout. The vivosmart 5’s display is legible but muted, with thick bezels that make it look a generation older. Neither band looks like a smartwatch, which is the point; if you want discreet, both deliver. Fitbit wins on polish, though the difference is cosmetic rather than functional.
Heart rate and GPS accuracy (Fitbit Charge 6 wins — major)
Fitbit upgraded the heart-rate sensor in the Charge 6 and added built-in GPS; Garmin relies on its established Elevate optical sensor but ships the vivosmart 5 without onboard GPS, requiring your phone for route tracking. In practice, both bands produce respectable heart-rate data for steady-state cardio, and both can drift during high-intensity intervals — a limitation of wrist optics generally, not of either product. The decisive point is GPS: if you run or cycle without your phone, the vivosmart 5 simply cannot record your route. That is a hard functional limitation, not a quality nuance, and it makes this criterion a clear win for Fitbit for outdoor exercisers.
Battery life (Garmin vivosmart 5 wins — moderate)
On paper both promise up to seven days. In real use the vivosmart 5 gets there because its display does less; the Charge 6 lands closer to four or five days, especially if you use the always-on display or frequent GPS workouts. Neither is bad — both outlast any smartwatch — but Garmin’s advantage compounds. With the Charge 6 you will think about charging roughly weekly; with the vivosmart 5 you might go ten days between charges. For travelers and people who resent cable management, Garmin wins, and the gap is noticeable rather than trivial.
Smart features (Fitbit Charge 6 wins — major)
This is not close. The Charge 6 offers Google Wallet contactless payments, Google Maps turn-by-turn mirroring, YouTube Music controls, and — on Android — quick replies to notifications. The vivosmart 5 supports notifications and Garmin Pay on some variants, but no replies, no music control, no maps. If your ideal device is 80 percent fitness tracker and 20 percent smartwatch, Fitbit built your band. If you consider wrist notifications a minor bonus, Garmin’s bare-bones approach costs you nothing. The winner is Fitbit, and the significance depends entirely on how much you value wrist smarts — for some buyers this is the whole decision.
Sleep and health tracking (Fitbit Charge 6 wins — moderate)
Both track sleep stages, resting heart rate, and blood oxygen, and both produce a daily readiness-style score. Fitbit’s sleep staging and Daily Readiness are among the best in the industry — but the most useful layer sits behind Fitbit Premium, which is bundled for a limited trial and then bills monthly or annually. Garmin’s sleep score and Body Battery metric are less granular but completely free, and Garmin’s health snapshot gives a one-screen daily summary. Fitbit also offers an ECG app for heart-rhythm assessment, which Garmin lacks at this price. Fitbit wins on depth; the subscription caveat keeps it from being a runaway.
Workout and training data (Garmin vivosmart 5 wins — moderate)
The Charge 6 offers more than forty exercise modes and solid cardio metrics, but Garmin’s athletic heritage shows. The vivosmart 5 estimates VO2 max, calculates training status and load, and assigns a fitness age — the same metrics Garmin uses on its running watches, just in a slimmer body. For someone building a training habit or curious about progressive fitness, Garmin’s data tells a more useful story over months. Fitbit’s daily-readiness framing suits general wellness more than structured training. Garmin wins for athletes; for casual movers the difference is academic.
App ecosystem and subscription (Garmin vivosmart 5 wins — major)
Garmin Connect is denser and slightly less friendly, but everything is free forever — every metric, every trend, every export. The Fitbit app is cleaner and more motivating for beginners, but after the Premium trial ends, the free tier holds back the deepest insights. Over two years of ownership, Premium costs roughly as much as the band itself. If you object to subscriptions on principle, Garmin wins decisively. If you would happily pay for coaching-grade sleep and readiness insights, the gap narrows considerably.

Garmin vivosmart 5: Pros and Cons
Pros:
- Consistently delivers 6-7 days of battery life
- Everything is free in Garmin Connect — no paywalled metrics
- Athlete-grade metrics: VO2 max, training load, fitness age, Body Battery
- Natural stepping stone into Garmin’s watch ecosystem
- Simple, distraction-light experience
Cons:
- No built-in GPS — phone required for route tracking

- Dated-looking display with large bezels
- Fewer exercise modes and no ECG
Who Should Choose What
Choose Fitbit Charge 6 if:
- You run, walk, or cycle outdoors and want to leave your phone behind
- You want tap-to-pay, maps, and music control without wearing a smartwatch
- You use an Android phone and want to reply to messages from your wrist
- You value polished sleep analysis and don’t mind a subscription for deep insights
Choose Garmin vivosmart 5 if:
- You charge devices as rarely as possible — a week-plus of battery is a priority
- You train with structure and want VO2 max and training-load trends
- You refuse to pay a subscription for data the device already collected
- You mainly exercise indoors or always carry your phone anyway
- You plan to upgrade to a Garmin running watch later and want ecosystem continuity
Skip both if: You want accurate GPS running data, on-wrist maps, and third-party app support — a proper GPS running watch or a budget smartwatch serves you better than either slim band.
Value for Money
Both bands sit in the same mid-price bracket, so the real value question is total cost of ownership. The vivosmart 5 is a one-time purchase: everything it measures, you keep. The Charge 6’s price tag is only the entry fee — Fitbit Premium, if you want the sleep depth and readiness coaching the device is marketed on, adds a recurring cost that can approach the hardware price over a couple of years. Without Premium, the Charge 6 is still a good tracker, but you are consciously declining its best features.
Whether the premium is worth it depends on engagement. If you will actually read daily readiness scores and follow guided sleep insights, Premium can justify itself in behavior change. If you just want steps, workouts, and sleep basics, paying for it is money burned, and Garmin’s free-everything model is flatly better value. For the subscription-averse and the data-hungry, the vivosmart 5 offers more lasting value; for the Google-integrated user who will use payments and maps daily, the Charge 6 extracts more value per dollar even with the upsell.
Final Verdict
For most buyers weighing these two, the Fitbit Charge 6 is the better all-round choice: built-in GPS, a sharper display, and genuinely useful smart features make it feel like a modern device rather than a legacy band. Choose it if you exercise outdoors phone-free or want wrist payments and maps — those are capabilities the vivosmart 5 simply does not offer.
Choose the Garmin vivosmart 5 if your priorities are battery endurance, subscription-free data, and training metrics that grow with you. It is the better long-term ownership proposition and the better athlete’s tool; it is simply the worse smartwatch.
The deciding factor comes down to one question: do you want your tracker to also act like a tiny smartwatch? If yes, buy the Charge 6. If no — if you want a quiet, long-lasting measurement device — the vivosmart 5 rewards that restraint. Neither is a wrong purchase, but buying the one that matches your actual wrist habits is the difference between a device you wear for years and one that ends up in a drawer.
Frequently Asked Questions
Can the Garmin vivosmart 5 track runs without a phone?
It will record your run’s duration, heart rate, and calories without your phone, but it cannot record GPS distance or route without connected GPS from a paired phone. If you regularly run phone-free, the Charge 6’s built-in GPS is the safer choice.
Does the Fitbit Charge 6 require a Premium subscription?
No — the band works fully without it, and basics like steps, workouts, heart rate, and a daily sleep score remain free. However, Daily Readiness, extended sleep analytics, and long-term trends are Premium features. Budget for the subscription if you want the complete experience Fitbit advertises.
Which band has better sleep tracking?
The Charge 6, on depth. Fitbit’s sleep staging and readiness scoring are more detailed than Garmin’s, though the richest layer needs Premium. Garmin’s free sleep score and Body Battery are still very usable and cost nothing extra.
Are either of these a good stepping stone to a running watch?
The vivosmart 5 is. It uses Garmin Connect and the same metrics (VO2 max, training status) as Garmin’s Forerunner line, so upgrading later feels seamless. The Charge 6 is more of a destination device — capable for casual running, but Fitbit’s ecosystem points toward wellness rather than structured training.
Which one should iPhone users pick?
The Charge 6 still works well with iPhones for tracking and notifications, but quick replies and some integrations are Android-only. If you are on iPhone and mainly want tracking with long battery life, the vivosmart 5 loses less functionality and may be the more coherent pairing.
