# Sub vs 不单

The clearest difference is update cadence: Sub at every 2 weeks against 不单's every 5 weeks. 不单's advantage is iOS requirement (11.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Sub sells 10 in-app purchases, starting at $1.99 per 7 days and 不单 sells 8 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.

Sub ships an update every 2 weeks, 不单 every 5 weeks. The most recent releases landed on October 29, 2026 and October 27, 2026 respectively.
