Sunday: AI Fitness & Run Coach
Workout Tracker, GPS & Plans
Free
Coach Carrot can run on your iPhone. Ask about your training, plan a week or draw a route, and with an on-device model nothing you ask leaves the phone.
Sunday is a training app with a coach you can message any time. Coach Carrot knows the workouts you have done, so you can ask about yesterday's run or next month's race and get an answer that actually fits you.
Every workout you record gets a short note from Carrot. The note points out what went well and what to watch next time. It feels a bit like having a coach who read your training log before you walked in.
Planning takes about a minute. Open Plan Studio, pick your sports, the days that work for you and how many hours you have, and Carrot lays the plan out across your week. Planned sessions can go straight into your calendar.
You can also build sessions just by describing them. Ask for five intervals of three minutes at 120 percent and the workout redraws itself. Routes work the same way. Ask for a hilly 15 km loop and Carrot draws one that brings you back to where you started. Once you head out, Carrot counts you in and calls out every change, out loud and on your Lock Screen, so you never need to look down at your phone.
Your numbers come with plain explanations. Fitness, fatigue and form show where you stand right now, and recovery readiness tells you if today is a day to push or a day to take it easy. For more detail there are personal bests, pace and power curves, heart rate zones and tools for planning your next race.
Snap Food lets you photograph a meal and log it in a few seconds.
Training is more fun with other people around. See where your friends have been active on the map, join group workouts near you, take on challenges and keep the conversation going in chat. You also earn XP and level up as you train.
Sunday lives on your Home Screen and Lock Screen too, with widgets for your next workout, recovery score, streak, weekly goal and a lot more.
You choose what powers Coach Carrot. On an iPhone that supports Apple Intelligence you can point the coach at the on-device model, and everything you ask stays on your phone. It is a per-device setting, so nothing about how you train has to leave the device.
Sunday syncs with Garmin and works with Apple Health. With your permission it reads your workouts from HealthKit, so sessions recorded in other apps and on other devices show up in Sunday on their own.
Sunday is free to download and available in 18 languages.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Coach Carrot can now run on more phones without the cloud. Next to Apple Intelligence you can download Gemma, Qwen, Phi or DeepSeek in Settings > AI Coach, and what you ask stays on the phone.
Not sure the model on your phone is up to it? Settings > AI Coach > Test Coach Carrot asks it 18 training questions and checks every answer.
Plan Studio and Route Studio work on the on-device model too. Describe your week or your loop in one sentence and Carrot fills in the rest.
The explore heatmap has been redrawn. It now shows your routes as lines, hotter where you go often, and there is a Year in Heat screen and home-screen widget to go with it.
Route maps show arrows and badges for sharp turns and steep descents, and the weather along the way.
You can chat with Coach Carrot offline with a downloaded model, and dictate your messages.
Plus fixes, including place names in Ireland and loops in Route Studio that came out the wrong size.
