# CalMotion vs 吃有数

The clearest difference is ads: 吃有数 at none against CalMotion's shown. 吃有数 also leads on monetization model (free vs freemium). CalMotion's advantage is ratings volume (68 vs 3). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. CalMotion sells 2 in-app purchases, starting at $7.99 per 3 months and 吃有数 sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for CalMotion against 5.0 for 吃有数. That said, the two scores are not equally well evidenced: CalMotion has 68 ratings behind it against 3, so its average is the more settled of the two. Written reviews are what separate them: 95% of CalMotion's written reviews are positive against 98% of 吃有数's.

CalMotion ships an update every 4 days, 吃有数 weekly. The most recent releases landed on October 22, 2026 and October 23, 2026 respectively.
