# Fuel Food Diary vs CalKit

The clearest difference is monetization model: CalKit at free against Fuel Food Diary's free with in-app purchases. CalKit also leads on review sentiment (60% vs 38%) and update cadence (every 5 days vs fortnightly). Fuel Food Diary's advantage is device support (3 vs 1). On price, rating, ratings volume and ads there is nothing between them.

Both are free to download. Fuel Food Diary sells 2 in-app purchases, starting at $0.99 per month and CalKit sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Fuel Food Diary holds the better App Store score, 4.4 against 4.3. Both are backed by a comparable volume of ratings — 19 and 15 respectively. Written reviews complicate that: 38% of Fuel Food Diary's written reviews are positive against 60% of CalKit's, so the app with the better star average is not the one people write more warmly about.

Fuel Food Diary ships an update fortnightly, CalKit every 5 days. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
