What’s on today, and what to change

Open the app and you already know which day of your routine is next and what weight to try. Your friends, right at the top.

  • Today’s day, or pick another one from your routine on a calendar
  • A free workout with no routine, or repeat one you already did
  • Today’s advice, worked out from your own sets
  • Your cards, in the order you like

Spin the plate or tap an icon to see the rest

One workout, start to finish

Open it, train, and leave with your numbers

No half-hour setup before you train. The routine knows where you left off and the rest timer starts by itself.

What’s next, firstAnd if you don’t fancy legs today, switch days without breaking the routine.
Logging without thinkingThe current set, highlighted. The rest timer keeps counting with the screen off and shows from any tab.
And you leave with your numbersFix the duration if you forgot to stop, save the changes to the routine and choose when you’ll be back.

Chuzi’s advice

It doesn’t tell you to train.
It tells you what to change.

Six rules read your history and compete to speak: coming back after a break, going up in weight, a stalled exercise, an abandoned one, a muscle falling short or a slow week. Only the one that matters most to you today shows up.

Friends and ranking

Train with your people, compare yourself with everyone

Invite with a code, do the same routine each at your own pace and compare the results when you finish. If you want, your records count in a global ranking that tells you where you stand.

  • Inviting is sharing a codeSend it however you like, they type it in their app and you’re friends.
  • Train togetherPick a routine, everyone does it on their own phone and at the end you see everyone’s weights. Nothing distracts you while you train.
  • Your profileYour avatar, your streak and the lifts you choose. Your friends see it, everyone does, or nobody: you decide.
  • Routines and gym plansSend a friend a ready-to-use routine, or suggest a time and see who joins.
  • Your progress, only if you want“Share progress” comes switched off, and you switch it off in the same place.

Wear OS

Leave your phone in the locker

With the watch you confirm every set from your wrist. You see the exercise, the weight, the reps and the rest left, and anything you change reaches your phone right away.

  • Confirm the set and fix reps or weightWith the previous set one tap away, in case you repeat it.
  • Heart rate goes into the summaryAverage and peak for the workout, measured only while you train.
  • Tile and complicationThe current set, without opening the app.

Goals

Your 100 kg bench, with a progress bar

Set a goal for each exercise, see how far you have left and let Chuzi celebrate the day you get there.

Progress

12 weeks at a glance

Consistency, volume per muscle including indirect work, records as multiples of your bodyweight and a streak badge that evolves with you.

Your way

Your bar, your plates, your week

The plate calculator uses the equipment you have, and you choose how many days to train, how the rest timer alerts you and how big the numbers are.

Reminders

When are you back?

When you finish, pick the day of your next workout and it reminds you that day. Changed your mind? Untick it.

Open their CSV and Chuzi recognises the exercises, understands kilos and pounds and duplicates nothing.

Export the whole app and restore it on another phone, no account needed. Or take your history out as CSV.

FAQ

What people usually ask

How much does it cost?

Nothing. There are no ads and no in-app purchases.

Does it work offline?

Yes. All workout logging is local: you can use the whole app in a basement with no signal. You only need a connection to sync, for the social side, for the cardio map and to look up food by barcode.

Do I need an account?

No. You can use it as a guest and nothing you log — workouts, weights, meals, routes — leaves your phone. The only thing that can leave is diagnostics: crash reports and a few usage events, without your data in them, and it comes switched off. An account gives you a backup, lets you recover your data when you change phones, and unlocks the social side.

Is there an iPhone version?

Soon. Right now Chuzi is an Android app that also works on Wear OS watches, and the iPhone version is on its way. Sign up for the notice and we’ll write when it’s out.

Can I bring my history from another app?

Yes, from Hevy and Strong. Export your history to CSV there and open it from Profile, in Your data: Chuzi recognises the exercises, understands kilos and pounds and doesn’t duplicate what you already had.
