# Elephant Folio vs Thread to Self

The clearest difference is device support: Elephant Folio at 3 against Thread to Self's 1. Thread to Self's advantage is iOS requirement (17.0 vs 26.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Elephant Folio sells 3 in-app purchases, starting at $4.00 per month and Thread to Self sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
