# Blue Switch vs diBlue

The clearest difference is rating: Blue Switch at 3.8 against diBlue's 2.8. diBlue's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, ratings volume, update cadence and device support there is nothing between them.

Both are free to download. Blue Switch sells 1 one-off in-app purchase. diBlue asks for nothing beyond the download.

Blue Switch holds the better App Store score, 3.8 against 2.8. Both are backed by a comparable volume of ratings — 43 and 18 respectively. Written reviews complicate that: 17% of Blue Switch's written reviews are positive against 40% of diBlue's, so the app with the better star average is not the one people write more warmly about.
