# RangeZero vs Gun Number

The clearest difference is iOS requirement: Gun Number at 13.0 against RangeZero's 17.6. On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. RangeZero sells 3 in-app purchases, starting at $2.99 per month and Gun Number sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
