Verdict
The clearest difference is rating: TSUN Smart at 5.0 against SEMS+'s 2.4. SEMS+'s advantage is update cadence (every 8 days vs every 6 weeks) and ratings volume (12 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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 2.4. That said, the two scores are not equally well evidenced: SEMS+ has 12 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 18% of TSUN Smart's written reviews are positive against 29% of SEMS+'s, so the app with the better star average is not the one people write more warmly about.
TSUN Smart ships an update every 6 weeks, SEMS+ every 8 days. The most recent releases landed on September 20, 2026 and September 22, 2026 respectively.
