# BMS Tool vs DT E

The clearest difference is in-app purchases: DT E at none against BMS Tool's 1. DT E also leads on ads (none vs shown) and iOS requirement (13.0 vs 15.0). BMS Tool's advantage is device support (4 vs 2). On price there is nothing between them.

Both are free to download. BMS Tool sells 1 one-off in-app purchase. DT E asks for nothing beyond the download.
