Wear OS Workout Tracker — GymPsycho
GymPsycho is a hypertrophy workout tracker for Android with a native Wear OS app. On a Pixel Watch or Galaxy Watch your current set, your rest timer, your heart rate and your next working weight sit on your wrist while the phone in your pocket keeps the log. It is free, needs no account, and this page is honest about what the watch does — and what it deliberately leaves to the phone.
What your watch shows during a workout
- The set you are on: exercise name, set dots for the sets already done, and the working weight and reps in numerals large enough to read mid-set — with a footer line carrying the workout duration and which exercise you are on.
- Your coach line: your last best set on this exercise — and with Pro, the on-device AI weight suggestion for the next one with a trend arrow.
- The rest timer: counts down to your rest goal when you set one, counts up when you did not, and shifts from green to yellow to red as the pause grows.
- A haptic nudge: a short pulse on your wrist each time the rest timer crosses a phase, so you can look away from the screen.
- Tap to restart rest: tap the timer on the watch and the rest restarts on the watch and on the phone at the same time — the one control the wrist owns.
- Live heart rate: measured on the watch through Health Services during the workout; average and peak land in the workout summary on your phone.
- Cardio work: distance and duration in the same large readout for treadmill, bike or rower entries.
- An ongoing activity: the workout stays reachable from your watch face while it runs — its notification carries your set count and rest target — and the screen stays awake so a glance is enough.
- PRs and the finish: a new personal record fires a celebration on your wrist with the lift and the number, and finishing brings a summary screen with the total duration and your PR count.
- Your language: the watch interface ships in English, German, Spanish, French, Portuguese and Russian, and follows whatever the phone is set to.
What stays on the phone
The watch app is a companion, not a replacement. Sets are ticked off in the phone app — the watch mirrors that state and controls the rest timer, but it cannot mark a set as done. Your paired phone also has to be with you, because it runs the training history and the on-device AI that the watch displays. And the AI suggestion itself needs GymPsycho Pro; the watch app is free either way. If leaving your phone in the locker is the whole point for you, we would rather tell you that now than sell you a claim that does not hold.
Set up in four steps
- Install GymPsycho on your Android phone: Get GymPsycho from Google Play on the phone you train with. No account and no sign-up — the app works the moment it opens.
- Install the watch app from your watch: Open the Play Store on your Wear OS watch and install GymPsycho there. Because both apps ship together, the watch app appears for any watch paired with a phone that has GymPsycho installed.
- Allow heart rate (optional): Open GymPsycho on the watch. It asks once for heart-rate access. You can postpone the prompt and switch it on later in the watch settings — everything else keeps working without it.
- Start a workout on the phone: The watch leaves standby by itself and switches to the live workout screen. Finish or discard the workout on the phone and the watch returns to standby.

In one line: if your goal is to leave the phone in the locker, Hevy's Wear OS app does that today and ours does not. If you train with your phone anyway and want a wrist readout that tells you what to lift next — inside a tracker with no account, no cloud and no ads — GymPsycho fits better. Strong has no Wear OS app at all, so Android lifters there log on the phone with nothing on the wrist.

Which watches this runs on
- Wear OS 3 and newer: every Pixel Watch generation, Galaxy Watch 4 and newer, plus Wear OS watches from other makers. Galaxy Watches older than the Watch 4 run Tizen and are out.
- Round displays first: the layouts are tuned per watch size so nothing sits on the curved edge — verified screen by screen on 384, 456 and 480 pixel round emulators, from a 40 mm Galaxy Watch to a Galaxy Watch Ultra.
- Same numbers, both wrists: iPhone users get the equivalent Apple Watch app plus a Live Activity on the Lock Screen and Dynamic Island. Both watch apps are built from the same workout state, so a household on mixed platforms sees the same thing.
Frequently Asked Questions
Does GymPsycho work on Galaxy Watch and Pixel Watch?
Yes. The GymPsycho watch app runs on Wear OS 3 and newer, which covers every Pixel Watch generation, Galaxy Watch 4 and newer, and other Wear OS watches such as the OnePlus Watch 2 or Mobvoi's TicWatch line. Galaxy Watches older than the Watch 4 run Tizen instead of Wear OS and cannot install it.
Can I log sets from the watch?
No — and we would rather say so plainly. You tick sets off in the phone app; the watch is the live readout for the set you are on and the control for your rest timer. Tapping the rest timer on the watch restarts it on both devices. Set logging on the wrist is a deliberate gap, not an oversight: GymPsycho is built around a two-second logging flow on the phone.
Do I need my phone with me during the workout?
Yes. The GymPsycho watch app is a companion: your paired Android phone runs the workout, the training history and the on-device AI, and the watch mirrors it over Bluetooth or Wi-Fi. Leaving the phone in the locker is not supported, so if wrist-only training is your priority, pick a tracker that logs on the watch itself.
Does the Wear OS app track heart rate?
Yes. GymPsycho reads your heart rate through Wear OS Health Services during an active workout and shows the live value on the watch. When you finish, the average and peak are pushed back to the phone and appear in the workout summary. Heart rate is optional — deny or postpone the permission and everything else keeps working.
Is the Wear OS app free?
Yes. The watch app is part of the free GymPsycho app — no account, no ads, no extra purchase. One thing on the watch is Pro-only: the on-device AI weight suggestion for your next set. GymPsycho Pro is $6.99/month or $49.99/year with a 14-day free trial; free users see their last best set on the same line instead.
Does the rest timer alert me on my wrist?
Yes. The rest timer runs on the watch and buzzes with a short haptic pulse each time it crosses a phase, and it shifts colour from green to yellow to red as your rest gets longer. If you set a rest goal for the exercise the watch counts down to it and then counts the overrun up, exactly like the phone.
Curious what the AI on the coach line actually computes? That is Training Intelligence — weight prediction, plateau detection and per-muscle MEV/MAV/MRV volume, all on your device.
