marble 2.0

Marble 2.0 turns Trends into a coach. Everything is computed from your own logged sets, on your device.

New

• Your Lifts: estimated 1RM trend per lift with an honest verdict — progressing, holding, or adapted — compared at matched effort (RPE), so backing off never reads as stalling.
• Records: a feed of your genuine PRs in Trends, plus a quiet best-at-every-rep-count table for each exercise.
• PR in reach: while logging, Marble tells you when a weight or rep record is close enough to chase today.
• Double-progression hint: when every set tops 8 reps at the same load and manageable effort, Marble names the classic next step — with the evidence, never a command.
• Weekly Goal: set your sessions-per-week target and build a week streak that forgives — hit 4 weeks in a row to bank a flex week that absorbs a miss, and comebacks are celebrated.
• Monthly report: sessions, volume, and PRs with fair same-point-vs-last-month comparisons, plus short insights computed privately on your iPhone.
• Muscle groups now show weekly hard sets against the 10–20 set guide, count pressing/pulling assistance fractionally, and remind you when a muscle hasn't been trained lately.
• Send sessions to Apple Health (optional): completed training days export as strength workouts with your effort score, so Marble sessions count toward Apple's Training Load.

Improved

• One quiet, adaptive weekly-goal reminder that cancels itself once you've trained.
• Best Weight comparisons are now unit-safe across lb and kg.

Marble remains local-only: no accounts, no ads, no tracking.
