# CMB Maps vs Solar Explorer 3D

The clearest difference is in-app purchases: CMB Maps at none against Solar Explorer 3D's 1. CMB Maps also leads on review sentiment (67% vs 50%) and iOS requirement (6.0 vs 16.0). Solar Explorer 3D's advantage is rating (4.2 vs 4.0). On price, ratings volume, ads and device support there is nothing between them.

Both are free to download. Solar Explorer 3D sells 1 one-off in-app purchase. CMB Maps asks for nothing beyond the download.

Solar Explorer 3D holds the better App Store score, 4.2 against 4.0. Both are backed by a comparable volume of ratings — 14 and 24 respectively. Written reviews complicate that: 67% of CMB Maps's written reviews are positive against 50% of Solar Explorer 3D's, so the app with the better star average is not the one people write more warmly about.
