# Stress Solution vs Mayu

The clearest difference is ads: Stress Solution at none against Mayu's shown. Stress Solution also leads on monetization model (free vs freemium) and iOS requirement (15.0 vs 17.0). Mayu's advantage is update cadence (every 3 days vs every 6 weeks). On price, review sentiment, in-app purchases and device support there is nothing between them.

Both are free to download. Stress Solution sells 3 one-off in-app purchases and Mayu sells 4 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Stress Solution ships an update every 6 weeks, Mayu every 3 days. Both last shipped on November 11, 2026.
