# Zempy vs CaloPal

The clearest difference is review sentiment: Zempy at 63% against CaloPal's 23%. Zempy also leads on update cadence (every 3 days vs weekly) and iOS requirement (13.0 vs 16.0). CaloPal's advantage is monetization model (freemium vs subscription) and rating (4.4 vs 4.2). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Zempy sells 6 in-app purchases, starting at $9.99 per month and CaloPal sells 5 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

CaloPal holds the better App Store score, 4.4 against 4.2. That said, the two scores are not equally well evidenced: CaloPal has 285 ratings behind it against 38, so its average is the more settled of the two. Written reviews complicate that: 63% of Zempy's written reviews are positive against 23% of CaloPal's, so the app with the better star average is not the one people write more warmly about.

Zempy ships an update every 3 days, CaloPal weekly. Both last shipped on November 4, 2026.
