# Simple D vs Daylog

Simple D and Daylog 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. Simple D sells 1 one-off in-app purchase and Daylog sells 6 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on August 13, 2026 and September 26, 2026 respectively.
