# 问真八字 vs Coach Maker

The clearest difference is update cadence: Coach Maker at weekly against 问真八字's monthly. 问真八字's advantage is review sentiment (89% vs 75%) and iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. 问真八字 sells 3 one-off in-app purchases and Coach Maker sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

问真八字 ships an update monthly, Coach Maker weekly. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
