# DIY Sun Science vs VR Science Lab

The clearest difference is rating: DIY Sun Science at 4.4 against VR Science Lab's 4.1. VR Science Lab's advantage is update cadence (every 2 months vs every 6 months) and review sentiment (100% vs 92%). On price, ratings volume, ads and in-app purchases there is nothing between them.

DIY Sun Science holds the better App Store score, 4.4 against 4.1. Both are backed by a comparable volume of ratings — 21 and 13 respectively. Written reviews complicate that: 92% of DIY Sun Science's written reviews are positive against 100% of VR Science Lab's, so the app with the better star average is not the one people write more warmly about.
