# 凯心 vs 3D看图

The clearest difference is ads: 3D看图 at none against 凯心's shown. 3D看图 also leads on update cadence (every 3 weeks vs every 2 months) and iOS requirement (13 vs 15.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

凯心 ships an update every 2 months, 3D看图 every 3 weeks. The most recent releases landed on September 5, 2026 and September 21, 2026 respectively.
