Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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