waitz: AI Workout Tracker

Waitz is the training system built for serious lifters — progressive overload tracking, periodization, and AI coaching with offline-first reliability. Whether you're powerlifting, bodybuilding, running a hypertrophy block, or training calisthenics, Waitz covers the lane that Strong, Hevy, and FitNotes don't. AI COACHING THAT THINKS, NOT JUST GENERATES (Pro) Get daily readiness insights, post-workout analysis, and weekly training summaries from an AI coach that reads your history and understands your goals. Ask free-form questions — "Should I increase my bench press?" or "Am I overtraining?" — and get personalised guidance based on your actual training data. Not a progression table. A training partner. FREE: TRACK EVERY SESSION Workout logging, the 1,800+ exercise library, preset browsing, full workout history, and personal records are free forever. Pro unlocks the coaching layer. PERIODIZATION THAT WORKS (Pro) Training blocks with auto-regulation, deload management, and 4 progression models. The kind of structured strength programming dedicated apps charge £35/month for — Waitz does it at £5.99. ADVANCED SET TYPES, FIRST-CLASS Rest-pause, AMRAP, pyramid, tempo, and cluster sets — all native, no workarounds. Log drop sets and supersets with full support. A built-in rest timer with haptic feedback keeps you on pace between sets. 1,800+ EXERCISE LIBRARY — ALWAYS FREE Browse a comprehensive library covering barbell, dumbbell, bodyweight, machine, cable, kettlebell, and resistance band movements. Each exercise includes step-by-step instructions and body-part mapping. Create custom exercises for movements unique to your training. 500+ WORKOUT PRESETS Choose from strength, hypertrophy, endurance, and sport-specific routines — or build your own. Organise presets into folders, duplicate and customise them, and access recent favourites with a tap. FATIGUE & RECOVERY TRACKING (Pro) A body-part fatigue heatmap shows which muscles are fresh and which need rest. Log sleep quality, nutrition, stress, and hydration to refine recovery estimates. Evidence-based calculations recommend training zones so you push hard on the right days and recover when you need to. DEEP ANALYTICS Track personal records (1RM, total tonnage, e1RM estimates) and strength progression over time — built for progressive overload, not just nostalgic logs. Spot plateaus before they stall your progress. View muscle balance ratios, training consistency scores, body-part volume charts, and a workout heatmap calendar. Export your data to CSV anytime. OFFLINE-FIRST Log in the gym basement with no signal. All data is stored locally so the app works without a connection. When you're online, workouts sync securely across your devices with automatic conflict resolution. PRIVACY FIRST Your data is encrypted in transit, passwords are hashed, and row-level security ensures only you can access your records. No ads. No selling your data.
