What's New in Masso
2.0.8
August 15, 2026
AI coach reliability • Fixed the bug that made routine generation fail — the AI's reply was being cut off mid-JSON. • New: Settings → AI coach → Test connection. It pings the servers from your phone and tells you exactly what went wrong instead of a generic error. Say it once, and it sticks • "Dumbbells only." "Under 45 minutes." "No legs." Those limits are now enforced on the finished plan, not just suggested to the AI — and the plan shows what it was built from, so you can check. Your data is yours • Settings → Your data → Export: a full JSON backup plus a CSV of every set you've logged. Opens in Numbers, Excel, anything. More room on the free plan • Saved routines: 3 → 5. A cleaner exercise library • Merged exercises that were the same movement with different equipment, so every exercise now has its own demo image instead of sharing one.
