Verdict

The call

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.

CostPrice · In-app purchases · Ads · Monetization

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
