# Aurader vs OpenSub

The clearest difference is ratings volume: Aurader at 177 against OpenSub's 2. Aurader also leads on update cadence (every 4 days vs every 2 weeks) and rating (4.7 vs 4.5). OpenSub's advantage is review sentiment (100% vs 81%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Aurader sells 2 in-app purchases, starting at $0.99 per 7 days and OpenSub sells 2 in-app purchases, starting at $9.99 per year. Whichever you choose, the download price is not the number that matters.

Aurader holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Aurader has 177 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 81% of Aurader's written reviews are positive against 100% of OpenSub's, so the app with the better star average is not the one people write more warmly about.

Aurader ships an update every 4 days, OpenSub every 2 weeks. The most recent releases landed on November 11, 2026 and November 5, 2026 respectively.
