Tonnage is a gym workout tracker built around the number that
actually predicts growth: total volume moved. Most apps bury it.
We put it front and center — and logging is free forever, no account required.
Log a set in two taps, watch your tonnage climb, and let the AI coach
decide what comes next.
LOG FASTER THAN A NOTEBOOK
- Two-tap set logging with your last weights pre-filled
- Supersets, drop sets, warm-up sets and RPE
- Rest timer that starts the second you finish a set
- Extensive exercise library plus a custom exercise builder
- Fully offline — no signal needed in the basement squat rack
- Export your data any time. It's yours.
SEE PROGRESS, NOT JUST NUMBERS
- Total tonnage per session, week and muscle group
- Personal records and estimated 1RM for every lift
- Volume trends and muscle-group balance charts
- Calendar, streaks and complete training history
- Body weight and measurement tracking
AN AI COACH THAT USES YOUR REAL DATA
- Builds your next session from your logged history, not a generic template
- Suggests working weights and rep targets set by set
- Rebuilds the week when you miss a day or stall on a lift
- Ask it anything: form cues, exercise swaps, how to program a deload
BUILT FOR THE GYM FLOOR
- One-handed layout designed for use between sets
- [Apple Watch app / Widgets / Live Activities / Apple Health sync]

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• Auto weight progression (Pro): the app sets your next weight and reps from your past workouts. Reps go up until you hit the top of the range, then the weight goes up. If you stall, it suggests a lighter session.
• Bug fixes and stability improvements.
