# 笔试通 vs VOSP

The clearest difference is in-app purchases: VOSP at none against 笔试通's 10. VOSP also leads on iOS requirement (12.0 vs 17.0). 笔试通's advantage is device support. On price there is nothing between them.

Both are free to download. 笔试通 sells 10 one-off in-app purchases. VOSP asks for nothing beyond the download.
