# Toolbox PRO vs Sensors Toolbox

The clearest difference is price: Sensors Toolbox at Free against Toolbox PRO's $3.99. Sensors Toolbox also leads on rating (4.7 vs 4.5). Toolbox PRO's advantage is in-app purchases (none vs 2) and update cadence (fortnightly vs every 5 months). On review sentiment, ads and device support there is nothing between them.

Sensors Toolbox is free to download; Toolbox PRO costs $3.99 up front. Sensors Toolbox sells 2 one-off in-app purchases. Toolbox PRO asks for nothing beyond the download.

Sensors Toolbox holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Toolbox PRO has 3.5K ratings behind it against 160, so its average is the more settled of the two. Written reviews complicate that: 62% of Toolbox PRO's written reviews are positive against 58% of Sensors Toolbox's, so the app with the better star average is not the one people write more warmly about.

Toolbox PRO ships an update fortnightly, Sensors Toolbox every 5 months. The most recent releases landed on October 17, 2026 and October 15, 2026 respectively.
