# One Workbook vs Gravitio

The clearest difference is update cadence: Gravitio at every 3 weeks against One Workbook's every 12 months. One Workbook's advantage is iOS requirement (15.0 vs 17.6). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. One Workbook sells 1 one-off in-app purchase and Gravitio sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

One Workbook ships an update every 12 months, Gravitio every 3 weeks. The most recent releases landed on October 8, 2026 and October 6, 2026 respectively.
