# Markdown Reader vs SleepMaster

Markdown Reader and SleepMaster 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. Markdown Reader sells 1 one-off in-app purchase and SleepMaster sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Markdown Reader ships an update every 9 days, SleepMaster weekly. The most recent releases landed on November 9, 2026 and November 10, 2026 respectively.
