# HIIT vs Keelo

The clearest difference is ads: Keelo at none against HIIT's shown. Keelo also leads on update cadence (every 2 weeks vs monthly) and device support (4 vs 2). HIIT's advantage is review sentiment (91% vs 80%) and ratings volume (31K vs 6K). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. HIIT sells 11 in-app purchases, starting at $2.99 per 7 days and Keelo sells 9 in-app purchases, starting at $12.49 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 — 4.8 for HIIT against 4.8 for Keelo. That said, the two scores are not equally well evidenced: HIIT has 31K ratings behind it against 6K, so its average is the more settled of the two. Written reviews are what separate them: 91% of HIIT's written reviews are positive against 80% of Keelo's.

HIIT ships an update monthly, Keelo every 2 weeks. The most recent releases landed on October 29, 2026 and November 1, 2026 respectively.
