Run Fun Voice Coach

Run Fun is your voice-coached running app.

Talk to Minna while you run, or after a run, or before. She knows your last run, your recent training, your shoes, and your goals. She coaches you on form through conversation, not lectures.

Three things Run Fun does

Analyze. Film yourself running past your phone or upload a video. Get a biomechanical breakdown — foot strike type, foot strike angle, overstride, trunk lean — visualized as styled overlay videos you can share. Side view, rear view, treadmill, outdoor. Capture runs on your phone; cloud GPU handles the detailed biomechanical analysis and rendered styled videos that come back to your camera roll.

Run. Pair with Apple Watch and AirPods. Simon, your run coach, listens during your run and speaks only when something's worth saying. Silence is intentional — he's watching, not chatting. Krishna takes over for drills.

Shoes. Comparing two pairs back-to-back on a treadmill? James helps you tag, record, and rate.

Talk to Minna — your voice running coach across five modes

• Onboarding — Kai welcomes you and learns the basics • Coach — Minna, your day-to-day advisor on form, training, recovery • Analyze — Minna walks through your form video with you • Shoes — James, our shoe-fitting expert • Run — Simon listens during the run; Krishna takes over for drills

Five named voice coaches, one consistent voice across all of them. Powered by ElevenLabs voice AI. Your conversations stay associated with a random ID — no name, email, or phone collected.

What it's not

Not a medical device. Not a diagnostic tool. Not a substitute for professional coaching, physical therapy, or medical advice. Run Fun is a form-feedback and general-wellness app. If you're working through pain, talk to a pro.
