# SelfSpell vs GoodSleep

The clearest difference is update cadence: GoodSleep at every 4 days against SelfSpell's every 8 days. SelfSpell's advantage is iOS requirement (17.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. SelfSpell sells 1 in-app purchase, starting at $9.99 per year and GoodSleep sells 3 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

SelfSpell ships an update every 8 days, GoodSleep every 4 days. Both last shipped on November 5, 2026.
