# Xiaoxiang BMS vs Pass Ease

The clearest difference is in-app purchases: Pass Ease at none against Xiaoxiang BMS's 1. Pass Ease also leads on ads (none vs shown). Xiaoxiang BMS's advantage is device support (3 vs 1). On price and iOS requirement there is nothing between them.

Both are free to download. Xiaoxiang BMS sells 1 one-off in-app purchase. Pass Ease asks for nothing beyond the download.
