# Brain Test 4 vs Bubble Sort!

The clearest difference is ads: Bubble Sort! at none against Brain Test 4's shown. Brain Test 4's advantage is chart position (#108 vs unranked) and iOS requirement (15.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Brain Test 4 sells 12 in-app purchases, starting at $4.99 per 7 days and Bubble Sort! sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
