# Lean vs KeepCool

Lean and KeepCool 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. Lean sells 1 one-off in-app purchase and KeepCool sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Lean ships an update monthly, KeepCool every 4 weeks. The most recent releases landed on September 21, 2026 and September 9, 2026 respectively.
