# DaysUntilWhen vs AI.Assistant

DaysUntilWhen and AI.Assistant 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. DaysUntilWhen sells 1 one-off in-app purchase and AI.Assistant sells 5 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

DaysUntilWhen ships an update monthly, AI.Assistant every 3 weeks. The most recent releases landed on November 4, 2026 and November 8, 2026 respectively.
