Your strongest update yet. We rebuilt the Trophy Case, shipped a brand-new Exercise History screen, and gave you full control over every exercise in your library — all wired into smarter, more reactive workouts. NEW — EXERCISE HISTORY Tap "Previous" on any set mid-workout (or any exercise in your detail view) to see the full story of that lift. • A live est-1RM trend chart with 1M / 3M / 1Y / All toggles • Real projections from your real training: "At this pace, you'll hit 100 kg in 8 weeks" • Milestone ETAs for your next round number and your 1×, 1.5×, 2×, 2.5×, 3× bodyweight benchmarks • Every past session expands in place to show every set, every rep, every RIR • Best-set highlights, PR pills, and one-tap deep links to the workout that earned it REDESIGNED TROPHY CASE The horizontal scroll is gone. Trophies now live in a clean two-column grid sorted by your latest PR. Tap any trophy to open a brand-new detail sheet with the headline lift, a 90-day est-1RM sparkline with delta, and your full PR history for that exercise. Every event links straight to the workout where you earned it. Adapts to weight × reps, bodyweight, weighted bodyweight, and time-tracked exercises. EDIT ANY EXERCISE Finally. Rename any of the 870+ built-in exercises (or your custom ones). Swap the photo. Fix the muscle assignments. Change tracking type from reps to time. Update the YouTube link. Edit the instructions. A one-tap "Reset to default" button puts seeded exercises back exactly how they were — and your Strength Score keeps recognizing renamed lifts thanks to a smart name-history fallback. SMARTER WEEK GRID The home calendar got six clean treatments — done, today, planned, rest, missed, and unplanned. No more false "missed" marks for days you weren't supposed to train. Tap any tile to see what was planned versus what you actually logged: completed sessions show stats, planned days show the exercise list, rest days say so. EDIT WITH CONFIDENCE A new scope picker lets you choose exactly how far a program change should reach — Today only, This and future, or All workouts — each with an impact preview so there are no surprises. Mode banners across the top of every editable screen show exactly what you're editing: today's workout, the program template, or just viewing history. Completed sessions stay untouched. LIVE PREFERENCE UPDATES Switch units from kg to lbs, swap RPE for RIR, or toggle auto-warmup, and the change confirms inline with a quick toast — no app restart, no stale numbers. Mid-workout? Your in-progress sets stay exactly as you typed them, and a one-line banner explains the change. A CLEANER HOME NEXT WORKOUT PREVIEW Finishing a workout now shows what's next — program, week, day, and the exercises that are coming — powered by a single source of truth that home, summary, reminders, and widgets all agree on. No active program? You'll see a clean Start a Program CTA. PLUS • History rows now show "+N PR" with the live count — tap the pill to jump straight to the right place • Refreshed text hierarchy across the whole app so meaningful content reads brighter and meta reads quieter • Tighter motion, cleaner empty states, smarter skeletons, and a stack of fixes Train smart. Track everything. Keep stacking reps.
