# Hello Charly vs Revyze

The clearest difference is rating: Hello Charly at 5.0 against Revyze's 4.5. Hello Charly also leads on in-app purchases (none vs 12). Revyze's advantage is update cadence (weekly vs every 2 months) and ratings volume (278 vs 1). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. Revyze sells 12 in-app purchases, starting at $9.99 per month. Hello Charly asks for nothing beyond the download.

Hello Charly holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Revyze has 278 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 61% of Hello Charly's written reviews are positive against 76% of Revyze's, so the app with the better star average is not the one people write more warmly about.

Hello Charly ships an update every 2 months, Revyze weekly. The most recent releases landed on October 20, 2026 and October 30, 2026 respectively.
