The receipts.
Progress turns everything logged in Meal Scanner and Workout Log into trend lines — the view you'd open before a check-in with yourself, or before handing a summary to someone else.
Body weight over time, plotted against goal direction rather than shown as a flat table.
Sessions per week against your target training days, so a slipping streak shows up early.
Calorie and macro intake averaged over a chosen window, not just today's snapshot.
Track measurements beyond the scale — waist, chest, arms, whatever you choose to log.
Photos here are meant to last months or years for side-by-side comparison, unlike a meal scan that's only useful once. Each photo is copied into the app's own storage on capture rather than left in the OS's temporary camera cache, so a comparison from six months ago still opens correctly even after the phone has cleared its cache in between.
Progress can generate a shareable PDF report — weight trend, training volume and frequency, personal records, top lifts, and nutrition averages — sized to hand to a coach, trainer, or physician. It's a summary report, not a full data export; for a complete backup of everything logged, see Settings & Data.
