## What is RunKit?

Build your running workout on iPhone. Run it on Apple Watch.

RunKit is the fastest way to create custom running workouts for the Workout app: intervals, tempo, fartlek, hills, long runs. Set each step once, and your Watch guides you through every rep with pace and heart rate alerts.

BUILD ANY WORKOUT
• Warm-up, cooldown and as many interval blocks as you need
• Reps and recoveries by time or distance
• Targets per step: pace, heart rate, heart rate zone or cadence
• Alerts with a tolerance (exact, ±5", ±10", ±15")
• Presets, duplicate steps or whole workouts, notes on each session
• Folders to keep your library tidy

RUN IT ON YOUR WATCH
• Your workout waits in the Workout app: just press start
• Apple's native workout engine, with all its metrics and alerts
• Running, walking, cycling, swimming, strength and more activity types

SCHEDULE YOUR WEEK
• Pick a day for each workout and see your week at a glance
• Scheduled workouts sync to your Apple Watch automatically
• Optional sync with your iPhone calendar

### 5/5 — Super appli

*2026-07-21*

J’adore cette application alors je

### 5/5 — Brilliant for Customised Intervals

*2025-12-26*

This app is perfect for customised intervals! I’d been looking for an app that works so coherently with apple’s workout app. If I could request anything it would be smaller pace integers. Currently you can only set intervals in 5 second ranges; smaller increments would be great

### 5/5 — Great app for running workouts

*2025-12-08*

I’m really glad I found RunKit, as it allows me to easily schedule running workouts where I can use HR alerts to support easy running, and pace alerts for intervals!

It’s very straightforward to use, and I can use the native workout app on my Apple Watch to complete workouts, 5 stars!!!

### 5/5 — Entrainement triathlon

*2025-11-24*

Je m’entraine pour un triathlon et cette app m’aide beaucoup a planifier mes intervalles en natation, en vélo et à la course!

### 1/5 — Pas de support si bug

*2025-10-20*

App au top pour préparer ses séances. Hyper simple d’utilisation. Visuels clairs et efficaces. J’utilise la version premium depuis plusieurs mois. En revanche, depuis les dernières mises à jour sur ma montre et mon iPhone, PLUS RIEN NE FONCTIONNE . Malgré plusieurs tentative pour joindre le support et avoir envoyé 5 fois mon mail…pas de réponse. App désinstallée puis réinstallée et maintenant j’ai perdu toutes mes données. Bref je suis dégoûtée.

### 2/5 — Subscription error

*2025-10-14, version 1.30*

I couldn’t buy the subscription, an error message appears

### 5/5 — Great app

*2025-10-12*

Perfect app, one of the best that I used if you need custom workouts without annoying features, unfortunately apple broke synchronization for my apple watch (they stopped support it from 11 version of software) so I’m probably cannot use as i’m going switch to garmin

### 5/5 — Excellent

*2025-10-07, version 1.30*

Very useful, just a shame that you can’t buy lifetime access

### 4/5 — Great App!

*2025-09-02*

This is a great App especially to transfer your custom runs to your Apple Watch. Only thing I’m having trouble with is once I create a custom run when I try to share it with my running partner (share feature within the App) it doesn’t allow me to share. I can select the share but nothing comes up like messages/email/airdrop etc. Is there any help you can provide!

Otherwise Great App!! 5 out of 5 if we can fix the share feature. Otherwise 5 out of 5!!

**Developer response:** Hello, thank for your feedback
The share feature has been fixed, you can now share with your running partner without issues! 
Enjoy your running with RunKit :)

### 1/5 — Não funciona no Apple Watch Series 3

*2025-08-27, version 1.28*

Não consegui instalar no meu Apple Watch Series 3. Não é possível? Abandoram o Series 3? Estava tão esperançosa.
