# SensorLog vs Physics Toolbox Sensor Suite

The clearest difference is price: Physics Toolbox Sensor Suite at Free against SensorLog's $2.99. Physics Toolbox Sensor Suite also leads on update cadence (weekly vs every 2 months) and rating (4.7 vs 4.4). On ads, in-app purchases, monetization model and device support there is nothing between them.

Physics Toolbox Sensor Suite is free to download; SensorLog costs $2.99 up front. SensorLog sells 4 one-off in-app purchases and Physics Toolbox Sensor Suite sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
