# 比咚 vs Cerberus

比咚 and Cerberus are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. 比咚 sells 10 one-off in-app purchases and Cerberus sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

比咚 ships an update every 2 weeks, Cerberus every 9 days. The most recent releases landed on October 30, 2026 and November 6, 2026 respectively.
