# Run Trainer vs HIIT

The clearest difference is update cadence: HIIT at every 2 weeks against Run Trainer's monthly. Run Trainer's advantage is ratings volume (198 vs 34). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Run Trainer sells 3 in-app purchases, starting at $5.99 per month and HIIT sells 8 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.4 for Run Trainer against 4.3 for HIIT. That said, the two scores are not equally well evidenced: Run Trainer has 198 ratings behind it against 34, so its average is the more settled of the two. Written reviews are what separate them: 53% of Run Trainer's written reviews are positive against 57% of HIIT's.

Run Trainer ships an update monthly, HIIT every 2 weeks. The most recent releases landed on October 7, 2026 and October 6, 2026 respectively.
