# StingerEP1 vs Mendaco regression

StingerEP1 and Mendaco regression are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. StingerEP1 sells 3 one-off in-app purchases and Mendaco regression sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 25, 2026 and October 27, 2026 respectively.
