# Solplanet vs TSUN Smart

The clearest difference is rating: TSUN Smart at 5.0 against Solplanet's 3.5. Solplanet's advantage is review sentiment (43% vs 18%) and update cadence (every 9 days vs every 6 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

TSUN Smart holds the better App Store score, 5.0 against 3.5. Both are backed by a comparable volume of ratings — 4 and 1 respectively. Written reviews complicate that: 43% of Solplanet'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.
