# DragLights vs SGMP

The clearest difference is rating: SGMP at 4.0 against DragLights's 1.8. SGMP also leads on ads (none vs shown). DragLights's advantage is review sentiment (40% vs 0%) and update cadence (every 3 weeks vs every 2 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. DragLights sells 1 one-off in-app purchase and SGMP sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

SGMP holds the better App Store score, 4.0 against 1.8. That said, the two scores are not equally well evidenced: DragLights has 13 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 40% of DragLights's written reviews are positive against 0% of SGMP's, so the app with the better star average is not the one people write more warmly about.

DragLights ships an update every 3 weeks, SGMP every 2 months. The most recent releases landed on September 15, 2026 and October 10, 2026 respectively.
