# SolarGo vs NEPViewer

The clearest difference is rating: SolarGo at 3.3 against NEPViewer's 2.7. On price, review sentiment, ratings volume and update cadence there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

SolarGo holds the better App Store score, 3.3 against 2.7. Both are backed by a comparable volume of ratings — 7 and 3 respectively.
