# Bio vs Koffee

Bio and Koffee 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. Bio sells 3 in-app purchases, starting at $1.99 per 7 days and Koffee sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Bio ships an update every 2 months, Koffee monthly. The most recent releases landed on October 13, 2026 and October 11, 2026 respectively.
