# DynaMail vs KeyCard BBM

The clearest difference is review sentiment: KeyCard BBM at 84% against DynaMail's 33%. KeyCard BBM also leads on rating (4.7 vs 2.0) and ratings volume (1.6K vs 4). DynaMail's advantage is in-app purchases (none vs 2) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. KeyCard BBM sells 1 one-off in-app purchase. DynaMail asks for nothing beyond the download.
