# Audipo vs Kotoren

The clearest difference is ratings volume: Audipo at 1.9K against Kotoren's 4. Kotoren's advantage is review sentiment (95% vs 72%) and rating (5.0 vs 4.7). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Audipo sells 3 in-app purchases, starting at $1.99 per month and Kotoren sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Kotoren holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Audipo has 1.9K ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 72% of Audipo's written reviews are positive against 95% of Kotoren's.

Audipo ships an update every 2 months, Kotoren every 5 weeks. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
