Kuta is the treadmill training app for runners who want structured workouts without memorizing every speed change.
Choose from 23 coach-built treadmill sessions, including beginner intervals, HIIT, tempo runs, hill workouts, 12-3-30, VO2max sessions, and Norwegian-inspired threshold training. New in 2.0: describe a session in plain language and Kuta drafts it for you on-device.
NEW IN 2.0: AI WORKOUT CREATION
Kuta Pro now includes an on-device AI workout builder. Type something like "30-minute threshold run with 4 hill repeats", "Quick 20-minute VO2max session", "Fun fartlek with sprints and some hills", or "2-hour marathon block" and Kuta drafts a full warmup, main set, recoveries, and cooldown using your configured paces.
Review the draft, edit any interval, then save. The same plan runs in active mode, shows in history, repeats from the Last Workout card, and exports to Strava.
ON-DEVICE AND PRIVATE
Workouts are generated on your iPhone using Apple Foundation Models when Apple Intelligence is available. No cloud. No account. No prompt history sent anywhere. When Apple Intelligence is unavailable or turned off, Kuta falls back to a deterministic on-device synthesizer, so a safe prompt always produces a workout.

EXACT SPEED CUES
Kuta speaks every speed change out loud. Voice cues mix on top of Spotify and Apple Music at full volume. There is no ducking, no pausing, no awkward audio handoff. You hear the speed, you change the treadmill, you keep running.
INCLINE REMINDERS
When a workout calls for incline, Kuta shows the target percent on the active screen and announces it. Kuta does not pretend to control your treadmill. It tells you what to set and trusts you to set it.
REAL TREADMILL DISTANCE
Distance is calculated from the speed and time you actually ran. No GPS lies. No "0.0 km" because the app thought you were standing still. Standing rests, distance intervals, and mixed sessions all show accurate totals.
PACE PROFILE
Configure your marathon, half marathon, threshold, 10K, and 5K paces once. Every preset and every AI-generated workout uses those paces automatically. Change a pace and your workouts update.
STRAVA-READY SUMMARIES
Every completed workout produces a Strava description with the interval structure, total distance, incline, and recovery style. Copy and paste into Strava in two taps.
REPEAT ANY WORKOUT
Tap a recent workout from the home screen to see the full breakdown, then repeat it with one tap. AI-generated workouts repeat exactly, interval for interval.

PRIVACY
Kuta is 100% on-device. No account. No analytics. No tracking. No cloud sync. No third-party SDKs that collect data. AI generation runs on Apple Foundation Models locally on your iPhone. Your workouts and pace profile never leave the device.
DESIGNED FOR RUNNERS WHO ACTUALLY USE A TREADMILL
Kuta is not a generic interval timer and not a generic AI fitness app. It is built around the things that matter on a treadmill: exact target speeds, incline reminders, standing rests, music that does not dim, summaries that match what you actually ran, and AI that knows treadmill-specific session structures.
Built by a runner. Tested in real treadmill sessions.
