# Duoflow vs 奏折

The clearest difference is update cadence: 奏折 at daily against Duoflow's every 4 days. 奏折 also leads on iOS requirement (15.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Duoflow sells 4 in-app purchases, starting at $1.99 per month and 奏折 sells 7 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Duoflow ships an update every 4 days, 奏折 daily. Both last shipped on October 25, 2026.
