Verdict

The call

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.

CostPrice · In-app purchases · Ads · Monetization

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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