Workouts

Routines, sets and reps, a rest timer, and last session's weights filled in for you. Bring your Strong history with you.

📷

Snap a meal

Take a photo or type what you ate – AI estimates calories and protein. Barcode scan and everyday foods built in.

📈

Real daily burn

Steps from Apple Health or your Galaxy Watch, plus your training – and after two weeks it learns from your weight trend.

🔒

Private photos

Front, side and back photos with an outline of last time, a before-and-after slider and an AI comparison.

Your photos stay yours

Progress photos are locked with your password on your phone before they are uploaded. The server only ever holds a scrambled copy – nobody else can open them.
