# Grid vs Probs

The clearest difference is update cadence: Probs at weekly against Grid's every 5 weeks. Probs also leads on device support (3 vs 1) and iOS requirement (15.1 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Grid sells 1 in-app purchase, starting at $14.99 per year and Probs sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Grid ships an update every 5 weeks, Probs weekly. The most recent releases landed on October 13, 2026 and October 3, 2026 respectively.
