# RE vs SRE

RE and SRE 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. Neither carries in-app purchases, so what you see is what you pay.

RE ships an update every 4 months, SRE every 3 months. The most recent releases landed on October 5, 2026 and October 8, 2026 respectively.
