Kanni
Remembers your run for you
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
Most running plans can't tell whether you slept badly, missed a couple of runs, or are still shaking off a cold. kanni can — and adjusts your next workout accordingly.
kanni is an AI running coach that reads your recovery each day and shapes your training around it. Not a fixed schedule. Not a plan that only changes when you remember to update it. Something closer to a coach who's actually paying attention.
HOW IT WORKS
kanni starts with your data — heart rate variability, resting heart rate, sleep, recent training load — and checks in every day to gauge how you're recovering. When you're ready, it lets you push. When you're not, it eases off before you overreach.
You can talk to it the way you'd text a coach. Tired, traveling, or coming back from a break? Tell it, and your plan adjusts around real life — no restarting, no catching up.
BUILT ON REAL COACHING SCIENCE
Underneath the conversation is a proper training engine: acute-to-chronic workload balancing, training-load tracking, and structured build, peak, and taper periodization — the same principles coaches use to get runners to the start line healthy and sharp.
• Adapts daily, not weekly — your plan responds to today, not last Sunday
• Readiness-based coaching, guided by your HRV, resting heart rate, and training load
• Overtraining protection that eases you back before you dig too deep
• Race-ready: choose a 5K, 10K, half, or marathon and a date, and kanni maps the weeks between
BUILT FOR APPLE
kanni is native to iPhone and Apple Watch. Planned workouts sync to your wrist and the Fitness app through WorkoutKit, with pace, heart rate, and cadence tracked automatically. Outdoor, track, or treadmill — kanni follows along.
Whether it's your first 5K or a faster half, kanni adjusts to the runner you are today.
