# SmileAI vs SleepHack

The clearest difference is ads: SmileAI at none against SleepHack's shown. SleepHack's advantage is update cadence (every 6 days vs every 7 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

SmileAI ships an update every 7 months, SleepHack every 6 days. The most recent releases landed on October 11, 2026 and October 6, 2026 respectively.
