REBL - AI Strength Coach

REBL logs your training and suggests your next weights and reps with an engine that runs free, offline, on your phone. On top of that: an AI coach that writes your program around your sport and your goals.

THE ENGINE — FREE, OFFLINE
Sport or no sport, this is the core of REBL.
• Log sets in seconds, mid-workout.
• REBL suggests your next weights and reps from your training history. No account, no connection, no guesswork.

MADE FOR iPHONE DUO — NEW IN 2.2
• Open it: your workout queue on the left, the lift you're on to the right. Log a set, rest, move on — the next exercise is already there.
• Fold it mid-set and keep going on the outer display. The rest timer comes with you.
• Your Duo's finish, in the app: Night Sky when you're in dark, Star White in light. Settings > Finish if you'd rather have plain black or white.
• On every other iPhone, nothing moves.

KNOW WHERE YOU STAND
• Readiness score, computed from your own training — know how recovered you are before you lift. No wearable needed; connect Apple Health and it reads your sleep, heart rate variability and resting heart rate too.
• Home-screen widget puts readiness at a glance.
• Session intensity score when you finish a workout.

TRAIN FOR YOUR SPORT — FREE
• Pick your sport, or type your own — BJJ, cycling, soccer, pickleball, a marathon in the fall.
• The AI generates a program shaped by your sport's demands. Free.
• Put game and practice days on your schedule.
• Game-day protection, built into the engine: key lifts take on no new weight within two days of a game, while reps keep moving. You walk in fresh and still make progress.
• Season memory: REBL remembers your season and gives you a heads-up before the next one starts.
• If your sport races, REBL says race day. If it fights, match day. The app speaks your language.

TRAIN TOWARD A DATE
• Set a meet, race, or tournament date. Free: the countdown and where you stand — build window, sharpening, race week.
• With Pro, the coach builds your plan toward that date and writes your race-week taper.

REBL PRO — AI COACHING
• Weekly insights drawn from how you actually trained, not how you planned to.
• An adaptive program: the coach writes your training blocks and revises them as your training changes.
• Query Coach: ask anything about your training and get an answer grounded in your history.
• Form cues on your lifts.
• The goal-date plan and race-week taper, authored for you.

BUILT FOR LIFTERS
• Plate calculator, PR tracking, full stats.
• 600+ exercise library.
• Bodyweight and waist, tracked side by side in your profile.
• Apple Watch app — log from your wrist.
• Apple Health: connect your sleep, heart rate variability and resting heart rate to sharpen your daily readiness score. They're analyzed on your iPhone. REBL also saves your workouts to Health.

YOUR DATA STAYS YOURS
• Your workouts live on your device, synced privately with iCloud. AI coaching sends your training data to our AI provider only after you say yes.
• No accounts. No ads. No tracking.
