What's New in Proof
2.1.5
September 25, 2026
Proof now reads your history and tells you the next step for every lift. • Clear next steps. Build reps, repeat this weight, one more time, or add weight. Each one comes from your own sessions at that weight, never from a single good day. • Every record, named. Weight PR, rep PR, strength PR, or a volume PR. Proof says which, and what it was up from. • Second sets count. When your top set and the set after it both improve, Proof says so. When the second set falls off, it waits before suggesting more weight. • Live targets while you lift. "+1 to beat," "close to 12," or "try 145" on the set you're doing. • History learns how you train. Your strongest day, your rhythm, whether rest days help, and when your records tend to arrive. Only when the data backs it up. • Honest numbers. Records shows what you gained in the last 12 weeks, not all time. A lighter week is a lighter week, never a bad one. • Bodyweight lifts progress by reps, and a day off is context, not a verdict.
