# Brain3k vs Infoplane

The clearest difference is review sentiment: Infoplane at 50% against Brain3k's 0%. Brain3k's advantage is update cadence (weekly vs every 3 months) and rating (4.8 vs 4.4). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Brain3k sells 1 in-app purchase, starting at $19.99 per year and Infoplane sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Brain3k holds the better App Store score, 4.8 against 4.4. Both are backed by a comparable volume of ratings — 4 and 7 respectively. Written reviews complicate that: 0% of Brain3k's written reviews are positive against 50% of Infoplane's, so the app with the better star average is not the one people write more warmly about.

Brain3k ships an update weekly, Infoplane every 3 months. The most recent releases landed on June 5, 2026 and August 18, 2026 respectively.
