# MyWeight Assistant vs Body Diary

The clearest difference is rating: MyWeight Assistant at 4.0 against Body Diary's 3.5. MyWeight Assistant also leads on ratings volume (11 vs 2). Body Diary's advantage is ads (none vs shown) and update cadence (every 9 days vs every 3 months). On price, in-app purchases, monetization model and iOS requirement there is nothing between them.

Both are free to download. MyWeight Assistant sells 2 in-app purchases, starting at $1.99 per month and Body Diary sells 4 in-app purchases, starting at $1.49 per month. Whichever you choose, the download price is not the number that matters.

MyWeight Assistant holds the better App Store score, 4.0 against 3.5. That said, the two scores are not equally well evidenced: MyWeight Assistant has 11 ratings behind it against 2, so its average is the more settled of the two.

MyWeight Assistant ships an update every 3 months, Body Diary every 9 days. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
