## Review summary

Users broadly praise 10K Trainer for its simple, beginner-friendly design and flexible pacing, acting as a reliable coach that motivates newcomers and returning runners. The 10K version adds features like run mapping. Common complaints focus on monetization (paywalls), stability issues (crashes), progression flaws (vanishing intervals and limited pace/distance options), and weak customer support.

### Pros

- 10K version adds useful features like run mapping and extra options beyond the 5K app.
- Long-term reliability; many users report lasting positive results and continued use over the years.

### Cons

- Requires subscription/paywall to continue training after the initial period; many users dislike the forced pay model.
- App crashes, including crashes after paying, which can lock access to paid content.
- Progression issues: intervals can disappear and weeks become repetitive runs, with no pace/distance customization.
