# 破事儿 vs CoreFlow

破事儿 and CoreFlow 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. 破事儿 sells 4 in-app purchases, starting at $5.99 per year and CoreFlow sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly every 2 weeks. The most recent releases landed on October 28, 2026 and October 25, 2026 respectively.
