Bundle size now smaller Fix some progressive overload rules calculations

PUMPZZ now feels smoother from one workout to the next. - Clearer actions on workout and rest days - Quick Start stays available when you want to train - Reminders show which workout is coming next - Your next targets are easier to find after training - More polish and reliability throughout the app

Focus Mode shows one set at a time, with your previous result, exact target, rest timer, and quick controls. After your workout, Coach’s Receipt tells you what to do next: add weight, add a rep, repeat, or pull back. It also explains why. You can now choose your rest timer alert: Soft Tap, Pulse, Classic, Punch, Gym Bell, Triple Beep, or Silent.

This is a major speed and reliability update for the entire training flow. • Faster app launch and Today loading. • Quicker workout starts, set logging, exercise changes, and post-workout summaries. • Faster Progress, program details, and week navigation—even with a large workout history. • Start individual workouts from the Program Library without activating the full program. • Programs now preserve the correct week and cycle and recover automatically from stale workout starts. • Supersets now stay intact when saving programs. • Fixed incorrect Live Activity and coached-weight units. • Improved History states for returning users.

RepStack is now PUMPZZ. Same powerful workout tracking, now with a sharper name and a brand-new identity. Your workouts, progress, programs, and account remain exactly where you left them. Open PUMPZZ and keep getting stronger.

Your Strength Score is now front and center — see it move after every session.

RepStack is now a smarter gym workout tracker for strength training, progressive overload, and workout logging. New Strength Score onboarding shows where you are and turns your score into exact workout targets. Your first workout flow is smoother, with workout preview, schedule context, reminders, and a faster path to start training. Fixed fixed-weekday scheduling, rest days, and program cycles so Day A/B/C, workout weeks, and recycled programs stay reliable. Improved workout editing, exercise substitution, draft sessions, PR summaries, volume, and Strength Score impact after each workout.

RepStack feels snappier, faster, and better.

Edit exercises directly from the Today tab, making it faster to adjust your workout before you start. Schedule tracking is smarter now too: RepStack handles custom training days, missed workouts, and program-week progress more reliably.

This update makes RepStack a stronger gym workout tracker, strength training log, and progressive overload planner. New Strength Score: your score now understands more of how you actually train, including barbell, dumbbell, cable, machine, bodyweight, and accessory work. Better workout targets: RepStack now uses your strength profile, PRs, exercise history, and training data to suggest smarter weights and reps. Better Progress tab: see your strength profile by category, track bonus work, review PRs, and understand what is moving your score. Better live workouts: preview how today’s sets can affect your Strength Score, then see the result after your workout summary. Also improved: exercise replacements, starting weight estimates, workout plan preview, offline logging, rest timer flow, and general polish across the app.

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.

This update improves the RepStack workout tracker experience with smoother gym logging, smarter strength training insights, and better progressive overload guidance. What’s included: Improved workout logging flow for sets, reps, weight, and rest times Better Strength Score and PR tracking visibility Smoother program tracking for bodybuilding, powerlifting, and general fitness More reliable workout history, exercise progress, and training analytics UI polish across gym log, workout summary, custom programs, and progress screens Performance improvements and bug fixes for a faster training experience RepStack helps you log workouts, track strength progress, follow custom programs, build consistency, and know what to lift next.

Today's Session is yours. New: - Edit sets and reps from Today - Replace lifts, add exercises, or swap days when the gym is busy - Choose whether a change applies only today or every week - Faster target recalculation when your plan changes - Larger last-set rating sheet so next-session bumps and deloads are easier to control RepStack now feels less like a static workout log and more like the plan you can actually train with.

Live workout metrics — see your volume % change per exercise as you train, with arrows on every set showing if you're up or down from last time. E1RM tracks in your exercise list. Beat a personal record and a banner drops in with a haptic tap. Smarter weight suggestions — "Too Easy" now bumps your weight next session like it should.

Smarter Progression Engine The engine now coaches you set by set — not just uniform reps across the board. Each set gets its own target based on what you actually did last time. Recovery Weeks Deload weeks now automatically reduce your weight (60%) or volume. Your progress charts and PRs stay clean — recovery sessions don't pollute your data. Plateau Breaking Stuck after a reset? The engine shifts your rep range to break through instead of deloading again. Heavier weight, fewer reps — then back to normal. Technique Tips When an exercise stalls for 3+ sessions, you'll see suggestions like drop sets, pause reps, or tempo work. Different tips for compounds vs isolation. Difficulty-Aware Coaching Rate a session "Hard" and the engine holds your weight and reps instead of pushing you. Two hard sessions in a row? It nudges you forward with a rep. Faster Rebuilds After a deload, the engine ramps you back to your previous weight faster — mid-range reps instead of starting from scratch. Keyboard Fix Fixed an issue where the keyboard couldn't be dismissed on the onboarding screen.
