# Smart Tools Pro vs Sensor Logs

The clearest difference is rating: Sensor Logs at 5.0 against Smart Tools Pro's 3.3. Smart Tools Pro's advantage is update cadence (every 5 months vs every 88 months) and review sentiment (25% vs 0%). On price, ads, in-app purchases and monetization model there is nothing between them.

Smart Tools Pro costs $0.99 and Sensor Logs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Sensor Logs holds the better App Store score, 5.0 against 3.3. That said, the two scores are not equally well evidenced: Smart Tools Pro has 8 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 25% of Smart Tools Pro's written reviews are positive against 0% of Sensor Logs's, so the app with the better star average is not the one people write more warmly about.

Smart Tools Pro ships an update every 5 months, Sensor Logs every 88 months. Both last shipped on September 21, 2026.
