Otto

Personal health coach · iPhone and Apple Watch

Stronger,
week after week.

Otto learns how you live and suggests one small, realistic action at the right moment. Progressive training, everyday movement, simple nutrition and real rest.

Coming soon to the App Store How it works

Your first week with all of Otto open — no card required.

Otto's Today screen: a calm greeting, the current cycle and the one action that matters now.

The idea

The best plan is not the most complete one. It is the one you actually do. Otto keeps it small, clear and on time — and stays with you until it is done.

01

A cycle that breathes

Every four weeks, one goal. Every day, one session shaped to you — and when it is time to recover, Otto says so with the same clarity. Rest is part of the plan too.

4-week cycles · one day at a time
A recovery day in Otto: today is for recovering, with a gentle walk as the option.

02

Progress you can prove

Levels unlock by demonstrated capability, never by points. From wall push-ups to the floor: Otto keeps the whole path that brought you here, and shows you the next step.

Levels by real capability, not streaks
Otto's Evolution screen: your progression path with completed levels and the next one in sight.

03

Nutrition without counting calories

Meals with a clear protein source, an eating window if you want one, and a weekly review that changes one thing at a time. No macros, no mandatory scale, no guilt.

Private by design

Your health data never leaves your device.

Otto has no server, no account system and no third-party analytics. We cannot see your training, your sleep or anything about you — and that is how we want it.
