# One Brain vs Stroopid

The clearest difference is ads: Stroopid at none against One Brain's shown. Stroopid also leads on iOS requirement (9.0 vs 15). One Brain's advantage is rating (4.4 vs 4.0) and ratings volume (297 vs 5). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. One Brain sells 1 one-off in-app purchase and Stroopid sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

One Brain holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: One Brain has 297 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 59% of One Brain's written reviews are positive against 50% of Stroopid's.
