# Smart Calculator vs DeviceBeat

The clearest difference is in-app purchases: DeviceBeat at none against Smart Calculator's 1. DeviceBeat also leads on ads (none vs shown). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Smart Calculator sells 1 one-off in-app purchase. DeviceBeat asks for nothing beyond the download.
