# Deye Cloud vs TSUN Smart

The clearest difference is review sentiment: Deye Cloud at 69% against TSUN Smart's 18%. Deye Cloud also leads on ratings volume (280 vs 1) and update cadence (every 2 weeks vs every 6 weeks). TSUN Smart's advantage is rating (5.0 vs 4.8). On price, ads, in-app purchases and monetization model there is nothing between them.

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

TSUN Smart holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Deye Cloud has 280 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 69% of Deye Cloud's written reviews are positive against 18% of TSUN Smart's, so the app with the better star average is not the one people write more warmly about.

Deye Cloud ships an update every 2 weeks, TSUN Smart every 6 weeks. The most recent releases landed on October 18, 2026 and October 17, 2026 respectively.
