# SleepTimer vs SleepCycle

The clearest difference is in-app purchases: SleepTimer at none against SleepCycle's 1. SleepCycle's advantage is iOS requirement (18.0 vs 26.0). On price, ads and device support there is nothing between them.

Both are free to download. SleepCycle sells 1 one-off in-app purchase. SleepTimer asks for nothing beyond the download.
