# SelfOS vs Calorize

The clearest difference is ads: SelfOS at none against Calorize's shown. Calorize's advantage is ratings volume (21 vs 3) and device support (4 vs 1). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. SelfOS sells 3 in-app purchases, starting at $5.99 per month and Calorize sells 5 in-app purchases, starting at $9.99 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 — 5.0 for SelfOS against 4.9 for Calorize. That said, the two scores are not equally well evidenced: Calorize has 21 ratings behind it against 3, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

SelfOS ships an update every 2 weeks, Calorize every 10 days. The most recent releases landed on November 9, 2026 and November 13, 2026 respectively.
