# Purpose vs StructMemo

The clearest difference is update cadence: StructMemo at weekly against Purpose's every 2 months. Purpose's advantage is ratings volume (6 vs 1) and iOS requirement (15.1 vs 17.6). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Purpose sells 6 in-app purchases, starting at $11.99 per month and StructMemo sells 2 in-app purchases, starting at $2.99 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 Purpose against 5.0 for StructMemo. That said, the two scores are not equally well evidenced: Purpose has 6 ratings behind it against 1, so its average is the more settled of the two.

Purpose ships an update every 2 months, StructMemo weekly. The most recent releases landed on October 5, 2026 and October 14, 2026 respectively.
