RIRLift
Apple Watch strength log that sets your next weight from the RIR you logged last time.
Runs the actual workout on Apple Watch — set entry, rest timers, exercise swaps — while iPhone handles setup from a 500+ exercise library, so nothing needs a phone mid-set. Logs are local-first (they save without a signal) with optional Apple Health and iCloud sync, and a free AI Coach reads your logged RIR to set the next session's load entirely on-device: it says when it can't tell yet instead of guessing. Core features are free for everyone; RIRLift Pro adds Coach fine-tuning, all-time muscle trends and program-length tracking.
What holds up
- +Coach runs entirely on-device — 'nothing leaves the device' — not a cloud chatbot guessing at your training.
- +Logs work with no phone and no signal — set entry happens straight on the watch.
- +Core features (Coach, weekly volume map, recovery status) are free; Pro is only extra history and fine-tuning.
- +500+ exercise library, so you're not stuck with iPhone-only pre-set programs.
Mind the limits
- −Apple Watch and iPhone only — no Android version.
- −Coach says it 'cannot tell yet' in early sessions, so recommendations start vague until you log more sets.
