# 三省 vs 听图

The clearest difference is update cadence: 听图 at every 4 weeks against 三省's every 6 months. 听图 also leads on iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 三省 sells 3 in-app purchases, starting at $2.99 per month and 听图 sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

三省 ships an update every 6 months, 听图 every 4 weeks. The most recent releases landed on August 11, 2026 and September 4, 2026 respectively.
