# VitaminD vs AIDO

VitaminD and AIDO 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. VitaminD sells 2 in-app purchases, starting at $1.99 per 7 days and AIDO sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
