# MochiDay vs KeepWhen

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

MochiDay ships an update every 4 days, KeepWhen every 6 days. Both last shipped on October 31, 2026.
