GymAdapt: the lifting brain your screenless band does not have
Wear the band for heart rate and sleep. Open GymAdapt on your phone at the gym: it tells you what to lift and how heavy, plays a video of each exercise, and logs the set with one tap. When you finish, the workout lands in Apple Health as Traditional Strength Training, so it sits next to your band data. Free to use. Get GymAdapt free on the App Store →
Screenless trackers are the fastest-growing kind of wearable in 2026. Google launched the Fitbit Air ($99.99) in May, WHOOP has never had a screen, and the Oura ring is a ring. All three are good at what they measure: heart rate, heart rate variability, sleep, recovery and how hard a session was. None can count reps, tell a squat from a lunge reliably, or know the weight on the bar. That part is still on you, and a phone app does it best. If you are still choosing the tracker, read best fitness tracker apps first; this page is for after you have one.
What a screenless tracker records, and what it cannot
| Fitbit Air | WHOOP | Oura ring | |
|---|---|---|---|
| Heart rate, HRV, sleep | Yes | Yes | Yes |
| Recovery or readiness score | Yes (Google Health app) | Yes | Yes |
| Workout effort from heart rate | Yes, auto-detected exercise | Yes (Strain) | Yes, activity and workouts |
| Sets, reps and weight | No | Only if you type them into Strength Trainer | No |
| Tells you what to lift next or how heavy | No | No | No |
| Price | $99.99 band; Premium optional $9.99/mo | Membership | Ring plus membership |
| Phone app | Google Health, iPhone and Android | WHOOP, iPhone and Android | Oura, iPhone and Android |

So the split is simple. The band answers how recovered am I and how hard was that. The lifting app answers what do I do today, how heavy, and did I get stronger. You want both answers in one place, which on iPhone means Apple Health.

The ranking
How we ranked them. Three questions, in order: does the app do the work the band cannot (plan the session, pick the weight, log the set fast), does the finished workout reach Apple Health so your band app and your lifting app agree, and what it costs. GymAdapt is our app and we say so; where another app is better for you, we say that too.

How the data flows (iPhone)
- Connect Apple Health in your lifting app. In GymAdapt, tap Connect Health on your Profile (it is also under Settings → Account); Hevy, Strong and Fitbod each have an Apple Health switch too.
- Train with the band on. It records heart rate and effort as usual. Log your sets in the lifting app.
- Finish the workout. GymAdapt writes it to Apple Health as Traditional Strength Training with the start and end time.
- Let the band app read Apple Health. Since Google Health v5.05 (August 2026), the Fitbit app syncs with Apple Health both ways on iPhone, including workouts. WHOOP and Oura can also connect to Apple Health; check which data types each one reads in its settings.
Two caveats. First, some bands also auto-detect the same session from your heart rate, so you can see it twice; delete or merge the duplicate in the band app. Second, Google Health does not write HRV or skin temperature to Apple Health, so those stay in the Fitbit app.
WHOOP Strength Trainer or a separate lifting app?
If you only care about WHOOP counting the muscular load of your lifts, Strength Trainer is enough and keeps everything in one app. The trade-off: it is a log, not a coach. It does not build a program, pick your next weight or show exercise videos, and many members enter workouts after the session rather than set by set. WHOOP members on its forum also report typing every workout twice when they use a lifting app as well. If you want the plan and the progression, use a lifting app as the source of truth and let WHOOP read the heart rate side.
Which app for which band
| If you have… | Pair it with |
|---|---|
| Fitbit Air on iPhone, and want a plan and weights picked for you | GymAdapt (ours); workouts flow through Apple Health into the Fitbit app |
| Fitbit Air on Android | Hevy or Strong (GymAdapt is iPhone only) |
| WHOOP, and you just want lifts counted in Strain | WHOOP Strength Trainer |
| WHOOP, and you want a real program that progresses | GymAdapt or Fitbod, logged set by set |
| Oura ring | GymAdapt for the plan, or Hevy and Strong to log a program you already run |
| An Apple Watch as well | See Apple Watch workout apps; Hevy and Strong have watch apps, GymAdapt does not yet |

What is the best workout app to use with a Fitbit Air?
On iPhone, GymAdapt (our app): it plans and logs your lifts and saves each workout to Apple Health, which the Google Health app can sync. On Android, Hevy or Strong.
Can Fitbit Air track sets and reps?
No. Fitbit Air has no screen and does not log sets, reps or weight. It records heart rate, HRV, sleep and auto-detected exercise. Use a lifting app for the sets.
Does WHOOP track weightlifting?
WHOOP measures the heart rate side of a lifting session. Its Strength Trainer feature also lets you log exercises, sets, reps and weight so it can estimate muscular load, but it does not plan your workouts or pick your weights.
Can Oura track lifting?
Oura records activity and heart rate during a workout but has no set and rep logging. Pair it with a lifting app such as GymAdapt, Hevy or Strong.
Do GymAdapt workouts show up in the Fitbit app?
GymAdapt saves each finished workout to Apple Health as strength training. Since August 2026 the Google Health app can sync workouts from Apple Health on iPhone, so turn that sync on in the Google Health app.
Do I need a smartwatch to log workouts?
No. Your phone is a better logger than a small screen anyway. Wear the screenless band for heart rate and recovery and log sets on your phone between rests.
A coach, not just a counter, free to start
GymAdapt builds your plan and raises your weights from what you log. Free to start; code TRYFREE01 adds a month of Pro.
Get GymAdapt on the App Store → Free to start. Pro is $4.99 a month or $24.99 a year (7-day free trial), or $59.99 once for lifetime. iPhone only. In English, Spanish, Portuguese, French, German and Japanese.Sources
