# Chart Neo vs Read Your Body

The clearest difference is rating: Chart Neo at 4.8 against Read Your Body's 4.4. Chart Neo also leads on iOS requirement (13.6 vs 15.0). On price, review sentiment, ratings volume and update cadence there is nothing between them.

Both are free to download. Chart Neo sells 2 one-off in-app purchases and Read Your Body sells 2 in-app purchases, starting at $2.69 per month. Whichever you choose, the download price is not the number that matters.

Chart Neo holds the better App Store score, 4.8 against 4.4. Both are backed by a comparable volume of ratings — 72 and 195 respectively. Written reviews complicate that: 80% of Chart Neo's written reviews are positive against 81% of Read Your Body's, so the app with the better star average is not the one people write more warmly about.

Chart Neo ships an update every 6 weeks, Read Your Body monthly. The most recent releases landed on September 24, 2026 and September 19, 2026 respectively.
