You buy books and never read them. You fall asleep three pages in. You finish a page and cannot remember a word of it. You might even secretly hate reading, and you know it still has to get done. I built ReadMaxxing for two reasons. I loved video games and hated reading. Now, I have spent years training people to read better, myself included. So I put the two together. HOW IT WORKS 1. Set a page goal. How many pages a day. 2. Log the pages you read, from a real paper book. 3. Play games that train how you read. FREE, EVERY DAY - Your reading speed baseline and your Reading IQ - The reading log and your page goal, with no limit, ever - Three levels of the Path a day. That is nine games - The Vocabulary Check PRO - The Path with no daily cap, and every Circle beyond the first - The whole Games tab: every game, any time, no daily limit - Vision Expansion (only pro access) - Gem or Glass (only pro access) - The Gauntlet: a speed reading test, one word per flash (only pro access) - The Verbal Recall Test (only pro access) You read the books. The app trains the reader. Privacy Policy: https://readmaxxing.org/privacy/ Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is in-app purchases: Matrix Logic at none against ReadMaxxing's 2. Matrix Logic also leads on update cadence (every 5 days vs every 2 weeks). ReadMaxxing's advantage is ratings volume (6 vs 1). On price, rating, ads and device support there is nothing between them.
