Mazao

Android · offline · no account

Your training stays on your phone.

A strength log that plans your week, records sets while you are still under the bar, and shows whether the work is adding up.

Built by one lifter for his own training, and published in case it suits yours. It does not try to be the tracker for everyone.

Mazao's Today screen: a Pull session with three exercises and their target loads

A look inside

A finished session showing duration, records, total volume, notes and each exercise with its sets

Recorder

Log without leaving the rack

Weight, reps, effort, and whether the set went to failure. Correct or undo without digging through menus.

The Progress screen showing sessions in the last 7 days, a performance change, and per-exercise evidence

Progress

Whether it is working

Weekly adherence and a strength trend per exercise. When there is too little recorded to say anything, it says that.

Settings showing app lock, backup, restore and the analytics toggle

Your data

A backup file you own

An encrypted database on the phone, and a complete export you can keep. No account means nothing to lose access to.

Four things leave your phone

Your workouts, measurements and notes are never uploaded. This is the complete list of what does go out, and the privacy policy explains each one.

  1. Exercise illustrations

    Fetched from wger.de when you look at them. Nothing about you goes with the request, and the app works without them.

  2. Crash reports

    The published build reports failures so they can be fixed. Only failures: it does not sample a working session.

  3. Two usage counters

    Workouts finished, and days since install. Off by default, and only if you switch them on.

  4. Purchase state

    Only if you buy Pro. Google issues the receipt and it is validated under a random identifier. Your name, email and card stay between you and Google.
