Workout Buddy: AI Gym Coach
Muscle builder & lift tracker
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Your AI coach now lives on your wrist and Lock Screen: log sets from the watch or Dynamic Island, track RIR, and let Buddy build programs from a photo.
Meet Buddy — an AI coach that actually understands your training.
Workout Buddy is built around Buddy, an in-app AI coach powered by one of the world's most advanced AI models. This isn't a scripted chatbot or a canned-FAQ bot. Buddy genuinely thinks through your training — reading your real logged data (your history, your weekly volume, your PRs, your recovery) and giving you answers specific to YOU.
Ask Buddy anything: "Is my chest volume too low?" "Swap my Friday session for something shorter." Ask "Why did my bench stall?" and it reads your last six weeks, spots that your top set flatlined while your soreness crept up, and tells you what's actually going on — like a coach who's seen every session you've logged.
WHAT BUDDY DOES
• Builds you a complete, personalized program from a 2-minute quiz — goal, schedule, equipment, and experience.
• Creates a brand-new program OR rewrites your current one, right inside the chat.
• Adds or removes advanced intensity techniques on specific exercises when you ask.
• Confirm-to-apply: every change is proposed as a card, and nothing touches your plan until you tap approve. Coaching intelligence, your final say.
• Works by voice — ask hands-free with "Ask Buddy" through Siri and Shortcuts.
A COMPLETE TRAINING SYSTEM BEHIND THE AI
Buddy sits on top of a serious, science-based hypertrophy engine — so your plan keeps working even when you're not chatting.
WHY LIFTERS USE IT
• Auto-progression that thinks: it reads your objective strength trend (estimated 1RM) plus your weekly recovery, pump, and soreness feedback, then decides each week whether to add, hold, or pull back sets — keeping your volume in a personalized range so you grow without overreaching.
• Multi-day program and training-block planning, with an automatic deload at the end of each cycle.
• Fast set logging: weight x reps in a tap, a built-in rest timer, and smart suggestions carried from last week.
• Exercise library: a searchable database with history charts, instructions, animated demos, primary and secondary muscles, and per-exercise PR history.
• Automatic personal-record detection — with a celebration the moment you hit one.
• Progress visuals: bodyweight chart, workout heatmap, per-muscle volume bars, and streaks.
• Daily steps: pedometer-backed step tracking with a progress ring.
• Live Activity: your rest timer and active workout on the Lock Screen and Dynamic Island.
• Works offline, then syncs to the cloud the moment you're back online.

A dark, premium, one-handed interface designed to be used mid-set — fast, thumb-friendly, and distraction-free while you're under the bar.
