About this app

Stop doing plate math between sets.

Type the weight you want on the bar and Rack Math shows exactly which plates to load per side, based on your plates, your bar, and your gym. Build a list of

weights, and it tells you precisely what to ADD and REMOVE to get from each set to the next, so you spend your rest resting.

FREE, FOREVER

• Instant plate math for any weight, in lb or kg

• Your plate inventory: only weights you can actually make

• Bar diagrams that match what’s on the bar

• Build-on-bar: enter what’s loaded right now and work from there

Store update history

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

App Store

Version 2.2 · 2026-08-02
Train what’s actually recovered. • Freshest: a new generated session that answers “I’m here on an off day. What should I train?” Rack Math picks lifts from whatever your recovery says is most rested, without stealing from your next scheduled sessions, and builds the day’s plan around them. • Cardio, seen whole: your total cardio load is now tracked across activities, so swapping a walk for a run or a swim reads as the trade it is, not as backing off. Familiar kinds of effort also count more fairly toward recovery than brand-new ones. • Lock Screen: log your set right from the Live Activity: tap Done, then tap again to confirm, so a stray touch never logs a lift. • Plus bug fixes and…

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.
