# BMS Tool vs Replace Tracker

The clearest difference is ads: Replace Tracker at none against BMS Tool's shown. BMS Tool's advantage is device support (3 vs 1). On price, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. BMS Tool sells 1 one-off in-app purchase and Replace Tracker sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
