Log a set in a tap

One warm-tan accent does the whole job — highlights, progress, active state. Everything else is greyscale and shape. No neon, no streaks, no badges begging for your attention. Just your lifts.
Everything a working set needs. Nothing it doesn't.
Every interaction is tuned for real between-set use — fast, glanceable, forgiving of sweaty thumbs.
Rep ranges that nudge you up
Target a range like 8–10 instead of a single number. Hit the top on every working set and 45 lb suggests the next jump — double progression, automated.
A numpad for chalky hands
Weight and reps open a purpose-built pad that takes real gym numbers — up to two decimals, no half-pound snapping, and 0 lb for bodyweight work. Shown cleanly as 45 or 42.50, never 45.00.
Rest that keeps time for you
Logging a set arms an inline rest ring with +15s and Skip. It survives pause and app-kill, so a resumed workout stays honest to the wall clock.
Warmups stay out of your numbers
Flag a warmup and it is silently excluded from volume, PRs and previous-set seeding. Your stats reflect real working sets only.
Super-sets that take turns
Group exercises in a routine and the workout alternates between them, set by set. Rest starts when the round is done — with an optional short rest between exercises.
Add an exercise mid-workout
Tap Add exercise during a workout and pick a lift. Keep it for this workout only, or save it to your routine as well.
A weekly goal in minutes
Set the minutes you want to train each week. A bar on Progress fills as your sessions add up, Monday to Sunday.
Saves to Apple Health
Turn on Save workouts to Apple Health in Profile and each finished workout lands in the Health app and counts toward your Activity rings. Off until you choose it.
Progress
Charts drawn from your own lifts.
Weight, volume and estimated-1RM trends, your personal records and per-exercise history — all derived from the sets you actually logged. True Σ weight × reps volume. No fabricated demo data, ever.
- Automatic PR detection with estimated 1RM
- Weight, Volume and 1RM chart modes per exercise
- Session-by-session history you can tap into
- Clean empty states before your first workout
