# B3 U vs TinySong

The clearest difference is monetization model: TinySong at free with in-app purchases against B3 U's subscription. TinySong also leads on ratings volume (1.6K vs 1) and update cadence (fortnightly vs every 5 weeks). B3 U's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. B3 U sells 2 in-app purchases, starting at $29.99 per month and TinySong sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

B3 U holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: TinySong has 1.6K ratings behind it against 1, so its average is the more settled of the two.

B3 U ships an update every 5 weeks, TinySong fortnightly. The most recent releases landed on October 21, 2026 and October 24, 2026 respectively.
