# E vs O

E and O 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.

E ships an update every 3 weeks, O fortnightly. The most recent releases landed on September 8, 2026 and September 17, 2026 respectively.
