# SoundScope vs Check1.2

The clearest difference is update cadence: Check1.2 at every 2 days against SoundScope's monthly. Check1.2 also leads on iOS requirement (17.0 vs 26.1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. SoundScope sells 1 one-off in-app purchase and Check1.2 sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

SoundScope ships an update monthly, Check1.2 every 2 days. Both last shipped on October 31, 2026.
