## Description

RUN interval - Running Timer makes interval training simple and flexible. Create custom sessions with three effort targets—Hard, Easy, and Rest—using either time or distance. New Distance Goal repeats sets until the target distance is reached, and you can add warm-up and warm-down phases. The app provides clear audio prompts, vibrations, and a voice-over option that narrates upcoming intervals, pace, and distance so you can stay focused on your run. It supports Strava sharing and a full-featured Apple Watch app, plus the ability to log regular runs without looking at your phone.

Designed with privacy in mind, RUN interval stores data locally (Apple Health) and does not send your info to servers. Indoor mode removes GPS for treadmill runs, and you can customize sound or silent prompts. Detailed run summaries break down pace, distance, and heart-rate data by interval, and you can share highlights with friends or on Strava. Ideal for runners of all levels who want structured interval workouts, race work, and hands-free guidance.

## Review summary

RUN interval is lauded for a simple, affordable setup with customizable intervals, solid interval tracking, and strong Apple Watch integration. Users praise its straightforward interface, one-time purchase, and useful history of pace, distance, and heart rate. However, recurrent issues center on distance accuracy (GPS/mileage inconsistent across devices), unreliable audio/visual alerts (voice announcements too quiet or not delivered with music/earphones), and occasional data gaps (runs not counted or saved, especially when used with a watch). Some treadmill users report poor distance recording. Overall, great value for focused interval training, with caveats about reliability and feature completeness.

### Pros

- Easy to use and straightforward interface
- Highly customizable intervals (or use suggested intervals)
- One-time price with no monthly subscription
- Strong data tracking including mileage, heart rate, and progress/history
- Good Apple Watch integration and background music compatibility

### Cons

- Distance/mileage accuracy is off or inconsistent (GPS mileage varies across devices)
- Notifications/announcements are not reliably audible or delivered when using music/headphones (voice announcements too quiet)
- Occasional data loss or runs not counted/saved, especially when used with a watch
- Treadmill use is not well-supported; distance may not record reliably
- Lewer-than-all-in-one functionality; users want more features (heart rate, route map, interval pace)
