StrengthInsight — The Strength Trends App for WHOOP, Hevy & Strava
A free strength training analytics app. Upload a workout screenshot from WHOOP Strength Trainer, Hevy or Fitbit, or connect WHOOP and Strava directly via API — and get lift history, estimated 1RM trends, personal records, plateau detection, recovery overlays and an AI-generated next workout, instantly.
What StrengthInsight does
How it works
- Screenshot or Sync your WHOOP Strength Trainer session summary, your Hevy workout, or connect to Strava.
- Upload/Sync to StrengthInsight — AI extracts exercises, sets, reps and weights.
- Review your progression dashboard: estimated 1RM trends, lift records, plateau alerts, and an AI-generated next workout.
Why StrengthInsight exists
WHOOP Strength Trainer is a great session logger, and it now adds basic PRs and per-exercise trends. But it stops at the surface: no estimated 1RM line per lift, no plateau alerts when a movement stalls, and no link between your recovery and your output. StrengthInsight extracts your data from a screenshot and turns it into a deeper progression view — the layer WHOOP's basics don't reach.
Hevy and Strava users get the same treatment: per-exercise progression, plateau detection, and recovery-aware next-workout suggestions, with no manual logging.
