# BB vs Sumi

The clearest difference is review sentiment: BB at 90% against Sumi's 0%. BB also leads on rating (4.9 vs 3.0) and ratings volume (402 vs 2). Sumi's advantage is monetization model (free vs free with in-app purchases) and update cadence (every 5 days vs every 3 weeks). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. BB sells 5 one-off in-app purchases and Sumi sells 3 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

BB holds the better App Store score, 4.9 against 3.0. That said, the two scores are not equally well evidenced: BB has 402 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 90% of BB's written reviews are positive against 0% of Sumi's.

BB ships an update every 3 weeks, Sumi every 5 days. The most recent releases landed on October 23, 2026 and October 7, 2026 respectively.
