Hey Product Hunt! I built Iterio after struggling with two problems during my own certification studies: (1) my phone constantly breaking my focus, and (2) forgetting what I studied a week later. Most focus apps just block apps for X minutes. Iterio goes further with three lock levels—including a "complete lock" that prevents you from unlocking your phone at all until the timer ends. It even blocks Picture-in-Picture attempts (that sneaky workaround we've all used). But focus alone isn't enough. The second feature I'm most excited about is automatic spaced repetition: tell Iterio what you studied, and it generates review tasks at scientifically optimal intervals based on the Ebbinghaus curve (1, 3, 7, 14, 30 days). No more manually calculating when to review. Looking for beta testers who want free Premium access in exchange for honest feedback. What features would make this more useful for YOUR learning workflow? Beta signup: https://play.google.com/store/ap...
