# InterFasting vs Weight Diary

The clearest difference is ads: Weight Diary at none against InterFasting's shown. InterFasting's advantage is rating (4.8 vs 4.6) and ratings volume (352 vs 40). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. InterFasting sells 5 in-app purchases, starting at $3.99 per month and Weight Diary sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

InterFasting holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: InterFasting has 352 ratings behind it against 40, so its average is the more settled of the two. Written reviews complicate that: 89% of InterFasting's written reviews are positive against 96% of Weight Diary's, so the app with the better star average is not the one people write more warmly about.

InterFasting ships an update every 4 days, Weight Diary weekly. Both last shipped on October 25, 2026.
