# Blue Days vs Arc

Blue Days and Arc 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. Blue Days sells 1 in-app purchase, starting at $1.99 per year and Arc sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on October 4, 2026 and October 14, 2026 respectively.
