# MetroMonkey vs BlueSpy

MetroMonkey and BlueSpy 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. MetroMonkey sells 1 one-off in-app purchase and BlueSpy sells 7 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

MetroMonkey ships an update every 24 months, BlueSpy every 17 months. The most recent releases landed on October 3, 2026 and October 11, 2026 respectively.
