# Empty vs FastingCat

The clearest difference is ads: FastingCat at none against Empty's shown. FastingCat also leads on review sentiment (100% vs 70%) and update cadence (every 6 days vs every 6 months). Empty's advantage is device support (3 vs 1) and iOS requirement (15.6 vs 17.0). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. Empty sells 1 one-off in-app purchase and FastingCat sells 10 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

FastingCat holds the better App Store score, 4.9 against 4.5. Both are backed by a comparable volume of ratings — 95 and 55 respectively. Written reviews point the same way: 70% of Empty's written reviews are positive against 100% of FastingCat's.

Empty ships an update every 6 months, FastingCat every 6 days. The most recent releases landed on September 8, 2026 and August 7, 2026 respectively.
