# 小习惯打卡 vs iDay

The clearest difference is ads: 小习惯打卡 at none against iDay's shown. 小习惯打卡 also leads on update cadence (every 2 weeks vs every 2 months) and ratings volume (552 vs 71). On price, rating, review sentiment and in-app purchases there is nothing between them.

Both are free to download. 小习惯打卡 sells 4 in-app purchases, starting at $1.99 per month and iDay sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for 小习惯打卡 against 4.7 for iDay. That said, the two scores are not equally well evidenced: 小习惯打卡 has 552 ratings behind it against 71, so its average is the more settled of the two. Written reviews are what separate them: 91% of 小习惯打卡's written reviews are positive against 89% of iDay's.

小习惯打卡 ships an update every 2 weeks, iDay every 2 months. Both last shipped on October 24, 2026.
