# i長庚 vs T檢定

The clearest difference is in-app purchases: i長庚 at none against T檢定's 1. i長庚 also leads on iOS requirement (13.0 vs 15.0). T檢定's advantage is device support. On price there is nothing between them.

Both are free to download. T檢定 sells 1 one-off in-app purchase. i長庚 asks for nothing beyond the download.
