# S vs SEMS+

The clearest difference is rating: S at 4.2 against SEMS+'s 2.4. S also leads on review sentiment (37% vs 24%) and ratings volume (91 vs 12). SEMS+'s advantage is update cadence (every 8 days vs monthly). 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.

S holds the better App Store score, 4.2 against 2.4. That said, the two scores are not equally well evidenced: S has 91 ratings behind it against 12, so its average is the more settled of the two. Written reviews point the same way: 37% of S's written reviews are positive against 24% of SEMS+'s.

S ships an update monthly, SEMS+ every 8 days. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
