# HIITBURN vs OptimalFit

The clearest difference is rating: HIITBURN at 4.3 against OptimalFit's 3.4. HIITBURN also leads on ratings volume (245 vs 17). OptimalFit's advantage is update cadence (every 3 days vs every 3 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. HIITBURN sells 7 in-app purchases, starting at $19.99 per month and OptimalFit sells 2 in-app purchases, starting at $19.95 per month. Whichever you choose, the download price is not the number that matters.

HIITBURN holds the better App Store score, 4.3 against 3.4. That said, the two scores are not equally well evidenced: HIITBURN has 245 ratings behind it against 17, so its average is the more settled of the two.

HIITBURN ships an update every 3 months, OptimalFit every 3 days. The most recent releases landed on November 6, 2026 and November 9, 2026 respectively.
