# WATASHI IoT vs T3 Smart

The clearest difference is rating: T3 Smart at 5.0 against WATASHI IoT's 4.7. WATASHI IoT's advantage is review sentiment (44% vs 22%) and ratings volume (69 vs 3). On price, update cadence, ads and in-app purchases there is nothing between them.

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

T3 Smart holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: WATASHI IoT has 69 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 44% of WATASHI IoT's written reviews are positive against 22% of T3 Smart's, so the app with the better star average is not the one people write more warmly about.

WATASHI IoT ships an update every 3 months, T3 Smart every 5 months. Both last shipped on October 24, 2026.
