# May Diary vs VitalLedger

May Diary and VitalLedger 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. May Diary sells 3 one-off in-app purchases and VitalLedger sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly every 10 days. The most recent releases landed on September 10, 2026 and September 28, 2026 respectively.
