# G vs Sensors Toolbox

The clearest difference is rating: Sensors Toolbox at 4.2 against G's 3.7. Sensors Toolbox also leads on in-app purchases (none vs 2) and ratings volume (134 vs 9). G's advantage is ads (none vs shown) and update cadence (every 4 days vs every 7 months). On price, review sentiment, device support and iOS requirement there is nothing between them.

Both are free to download. G sells 2 one-off in-app purchases. Sensors Toolbox asks for nothing beyond the download.

Sensors Toolbox holds the better App Store score, 4.2 against 3.7.
