# EarUnion vs BSLLTER

The clearest difference is review sentiment: EarUnion at 100% against BSLLTER's 50%. EarUnion also leads on update cadence (every 5 weeks vs every 7 months). BSLLTER's advantage is rating (2.6 vs 1.0) and ratings volume (5 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

BSLLTER holds the better App Store score, 2.6 against 1.0. That said, the two scores are not equally well evidenced: BSLLTER has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of EarUnion's written reviews are positive against 50% of BSLLTER's, so the app with the better star average is not the one people write more warmly about.

EarUnion ships an update every 5 weeks, BSLLTER every 7 months. The most recent releases landed on September 27, 2026 and October 7, 2026 respectively.
