# RLM vs LogoLab

RLM and LogoLab 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. RLM sells 1 one-off in-app purchase and LogoLab sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

RLM ships an update every 3 weeks, LogoLab every 6 weeks. The most recent releases landed on October 15, 2026 and October 4, 2026 respectively.
