Store update history

Each store’s release notes, as the developer wrote them. They are the developer’s words, not ours.

App Store

Version 4.5.0 · 2026-10-09
1. New Workout Flow A redesigned workout experience that’s cleaner, faster, and easier to use mid-session. Everything from exercise cards and checkmarks is now accessible through a streamlined vertical layout with a floating toolbar and improved workout caching — so you can customize, track the progress of your workout, and finish workouts with fewer taps, zero friction, and no loss of progress on incomplete sessions. 2. Stopwatch & Timer Updates Updated to be more reliable, more responsive, and easier to control — so your timing works with your workout, not against it. Both the stopwatch and timer can now be used and running in the background while interacting with the rest of the app,…

Method and limits

What this report can and cannot show

What a missing label means

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.

Limits of this report

  • A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
  • Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
  • Not assessed is a state. It is never a zero and never a pass.
  • A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
