Describe it or paste a screenshot, and it's ready in seconds. Then just run: voice and haptic cues guide every interval, even with your screen off. 25 workouts runners actually love — HIIT, fartlek, tempo, hills, Yasso 800s. On iPhone and Apple Watch. Because running the same pace every day only makes you better at running the same pace. Break the plateau. EVERY RUN IS A NEW CHALLENGE Every workout here has a specific goal and a different feel — so you actually train different muscles, systems, and skills instead of just logging miles. Your running workout is fun now :) Speed: 200m pops, ladders, strides, sprint finishers Strength: Hill repeats, power builders, switchbacks Stamina: HIIT, Cruise intervals, tempo waves, Yasso 800s Endurance: Progressive aerobic, negative splits, scenic cruises Fun: Fartlek games, stoplight play, music flow runs Each workout has a warm-up, main set, and cooldown — with clear effort guidance through every phase. AI WORKOUT GENERATOR Tell the AI coach what you want — "30 minutes, hill repeats, moderate" or "a fartlek that doesn't bore me" — and get a runnable workout in seconds. Paste a screenshot of a workout you saw online and we'll convert it into intervals. TRAIN BY EFFORT, NOT NUMBERS Every interval shows a target effort (80% for work, 30% for recovery). No heart rate monitor needed. GPS pace lies anyway — effort just works better. AUTO-LAP BY DISTANCE OR TIME Distance intervals auto-complete when you hit 200m, 400m, 800m, or whatever target you set. Time intervals count down with precision. No fumbling with lap buttons mid-stride. AUDIO & HAPTIC CUES Get notified at interval start, halfway, and end. Works with your screen off, works on Apple Watch. Built for running outside, where you can't keep glancing at a screen. APPLE WATCH COMPANION Run straight from your wrist.

I wore my Apple Watch for years without really using what it was telling me. The data was there - precise, reliable - but never explained, never put into context. As a coach and athlete, I knew this data had value, but it wasn’t actionable. So instead of switching to another watch, I built Morphy. To understand my recovery, manage my training, and perform at my best.
