# ONO vs Light Rim

ONO and Light Rim 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. ONO sells 1 one-off in-app purchase and Light Rim sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ONO ships an update every 2 months, Light Rim every 6 weeks. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
