I've been building this since last November and it went to production on Google Play last week, so it's a good moment to get honest feedback from people who don't know me. My problem with brain game apps: you get points, streaks and confetti, but no idea if you're actually getting better. So in Brain Elo every round moves a rating, like in chess. There are four skill areas (logic, retention, attention, flexibility). Each one has its own rating, plus an overall one. People usually ask how Elo works without an opponent. Every round counts as a match against a virtual 1200 player. Your score becomes a number between 0 and 1, and you gain or lose points depending on how that compares to what your rating predicts. Everyone starts at 800, and your first 30 games in each area move faster so you get placed quickly. What's in it right now: - 22 short games. Some classics (Quick Math, Tower of Hanoi, Tap the Numbers) and some of my own (Switchyard, Synapse Switch, Spark Patrol) - a daily workout built around your weakest area - weekly leagues, and challenge links you can send to a friend - English, German, Spanish and Portuguese - free to play, no ads. Pro is an optional subscription for the full library I wanted to able to challenge my friends and have a fun simple daily game to pass time whilst commuting or just to have another option to avoid brain rotting Android: https://play.google.com/store/apps/details?id=com.greiner.brainelo iPhone: waiting on App Store review Browser: https://play.brainelo.de (limited) Two things I'd really like to know: which game feels unfair in your first round, and after 5 to 10 games, does the rating feel like it means something?   submitted by   /u/Psychological_Toe_66 [link]   [comments]
