# 一签通 vs 签字宝

The clearest difference is update cadence: 签字宝 at every 3 weeks against 一签通's every 3 months. 一签通's advantage is iOS requirement (11.0 vs 13.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 一签通 sells 7 one-off in-app purchases and 签字宝 sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
