# B3 vs Era

The clearest difference is update cadence: Era at weekly against B3's every 4 weeks. B3's advantage is ratings volume (5 vs 1) and device support (3 vs 1). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. B3 sells 1 one-off in-app purchase and Era sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for B3 against 5.0 for Era. That said, the two scores are not equally well evidenced: B3 has 5 ratings behind it against 1, so its average is the more settled of the two.

B3 ships an update every 4 weeks, Era weekly. The most recent releases landed on November 5, 2026 and October 31, 2026 respectively.
