# Pro vs Sensors Toolbox

The clearest difference is rating: Sensors Toolbox at 4.2 against Pro's 1.8. Sensors Toolbox also leads on ratings volume (134 vs 4). Pro's advantage is ads (none vs shown) and update cadence (every 3 months vs every 7 months). On price, in-app purchases and device support there is nothing between them.

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

Sensors Toolbox holds the better App Store score, 4.2 against 1.8. That said, the two scores are not equally well evidenced: Sensors Toolbox has 134 ratings behind it against 4, so its average is the more settled of the two.

Pro ships an update every 3 months, Sensors Toolbox every 7 months. The most recent releases landed on November 4, 2026 and November 2, 2026 respectively.
