# A vs onsA440

The clearest difference is rating: A at 4.4 against onsA440's 2.0. A also leads on ratings volume (185 vs 4) and update cadence (every 6 weeks vs every 5 months). onsA440's advantage is in-app purchases (none vs 4) and review sentiment (73% vs 61%). On price, ads and device support there is nothing between them.

Both are free to download. A sells 4 one-off in-app purchases. onsA440 asks for nothing beyond the download.

A holds the better App Store score, 4.4 against 2.0. That said, the two scores are not equally well evidenced: A has 185 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 61% of A's written reviews are positive against 73% of onsA440's, so the app with the better star average is not the one people write more warmly about.

A ships an update every 6 weeks, onsA440 every 5 months. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
