# IZI Study vs Intervalia

The clearest difference is update cadence: Intervalia at every 3 days against IZI Study's monthly. IZI Study's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. IZI Study sells 6 one-off in-app purchases and Intervalia sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

IZI Study ships an update monthly, Intervalia every 3 days. The most recent releases landed on October 5, 2026 and October 4, 2026 respectively.
