The logbook
Log a set in a couple of taps.
Weight, reps, and RIR, captured between sets. Fast enough that the session never has to wait for the app.
Watch it happen
Logged before you've racked the bar.
Type the weight, type the reps, tap Log. The set is saved and the rest timer is already running. This is the real screen, in real time.
The workout screen
Everything a set needs, nothing it doesn't.
Each exercise is a card; each set is one row with weight, reps, and a Log button. Open a card, like the one in the shot, and the details that matter are already laid out:
- Suggested vs previous weight. Flip between what Vasbyt proposes for today and what you actually did last time.
- Warm-up guide. Ramp-up sets calculated from your working weight, so you don't do that math cold.
- Set counter and session timer. Pinned to the bottom of the screen, so you always know where the session stands.
- Drag to reorder. The rack is taken? Move the exercise, keep the flow.
Plate calculator
The bar math, done for you.
Suggested weight says 95. What goes on the bar? The plate calculator answers in one glance, from any set row.
- Per side or total. See plates per side, or work backwards from a total target.
- Bar weight included. It knows the bar is part of the number.
- Exact plate counts. 45s down to 2.5s, counted out so you just load and lift.
Exercise intelligence
Small things that add up.
Rest timing, automatic
Logging a set starts the rest timer. No extra tap, no guessing how long you've been scrolling.
Pin your favorites
Pin the lifts you actually do and they surface first in the exercise picker, so there's less scrolling mid-session.
Bodyweight logic
Pull-ups and dips log reps without inventing a load, and added weight is tracked when you strap it on.
Variants stay separate
Barbell, dumbbell, and machine versions are tracked as their own lifts, so the history behind every suggestion stays honest.
