The logbook · free, for good
Built for the gym floor
Big targets, one-tap sets and a rest timer that runs itself. Every set you have ever logged stays yours, with no caps, no paywall and no card.
1 tap
Per set
Tick a set and it's logged, with last time's numbers right above it.
90 s
Rest timer
It starts when you tick a work set (two minutes for the big lifts) and tells you when to go again.
7 kinds
Of lift
Weights, bodyweight, assisted, holds, timed work, cardio with live pace and carries. Plate math and warm-ups too.
No cap
History
Every workout, record and e1RM you have ever logged, as far back as you go.

Off the phone, too
- Apple WatchWith iOS
One tap logs the set, your wrist buzzes when rest is over, and you can finish the workout without touching your phone.
- Live ActivityWith iOS
The lift, the set, the weight and the clock on your Lock Screen and in the Dynamic Island.
- On the web
Plan your week, read your progress and import your history on a big screen. Logging stays on your phone.
Coaching · Premium, when you want it
When you want a plan, turn one on
Rebar plans a block around your goal and your week, sets how much each muscle gets, and puts the deload on the calendar before you need it.
- A block, planned. Weeks that build to a peak and then a deload, with a set target for every muscle, every week.
- Adjusts to how it felt. Log how hard your sets were and Rebar moves next week's sets up or down from it.
- Sized for today. Add a lift and its sets come from the block's target, or let Rebar pick the whole session.
- Deloads on schedule. Past the beginner stage, the easy week is on the calendar, and offered early if fatigue builds.

Your record · free
Every lift, kept honest
Rebar keeps score so you don’t have to. Open Progress and see what moved.
- Records by lift
- Your best set and e1RM for every exercise, and how far each moved.
- A Strength Index that shows whether you’re getting stronger
- Every exercise is measured against its own past, so it tracks you, not a table of other lifters.
- Bodyweight, charted
- Weigh-ins and body fat over time, with a goal line if you set one.
- Cards worth sharing
- Set a record and it renders a clean card, one tap from anywhere.
