# CodeStreak vs BigO Algorithms

The clearest difference is iOS requirement: BigO Algorithms at 18.6 against CodeStreak's 26.2. On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. CodeStreak sells 2 in-app purchases, starting at $4.99 per month and BigO Algorithms sells 2 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.
