- When your sets use different weights, the heaviest one decides the next suggestion.

- The explanation of the arrows now appears right after setup, not only in your first workout.
- Once you have logged ten sessions, a reminder appears when your last backup is more than a month old.
Fixed
- An exercise you could not do used to count as a result and could break a deload streak. Skip it now, and the streak holds.
1.1, The first release: log your sets, and StackUp works out the next weight
, Feature release, News, 15 New,
News
StackUp is on Google Play: free, with no ads and no account. Your log stays on your phone.
New
- Auto-progression: go above your target rep range and the next session suggests more weight; fall below it and it suggests less. Every exercise gets an arrow, up, level or down, so you always see why.
- Three sessions below the range in a row bring a real deload: 90 % of your last weight instead of another small step.
- Override any mark when you know better.
- Splits: build your routine once, reorder it by dragging, and start a session from it. Six ready-made splits to begin with.
- 20 exercises to start from, and your own on top, each with its own number of sets if you want one.
- Sessions without a split, and a History tab with every session you have logged.
- Every exercise shows what you did last time, and takes a note of its own in every session.
- Edit a finished session: weight, reps, sets, marks, note and body weight. Everything you can set during a workout.
- The finish screen names every new personal best.
- A chart for every exercise, framed around your numbers rather than starting at zero, and one for your body weight. Switch any card between weight and volume, and see your three most recent personal bests on it.
- A training-frequency card that follows the range you pick.
- Back up your whole log to a file, and restore it later.
- Delete a session, or discard one you started by mistake.
- Kilograms or pounds.
- Fully in German, exercise names included.
