Read full descriptionHide full description
Focus with a system, not willpower. FocusSnap turns your smartphone into the ultimate "proctor." It's a new kind of focus app that records your study sessions with a unique mechanism. In beta testing, users increased their weekly study time by an average of 1.78x (*). We solve the problem of "I want to study, but I end up on my phone" with a system that doesn't rely on willpower. ■ Why your study habits don't stick It's not because your willpower is weak. It's because your phone is too tempting. FocusSnap doesn't ask for grit or discipline—it creates an environment where slacking off isn't an option, so you can perform at your best. ■ Three focus mechanisms 1. Random photo capture — your phone becomes a proctor While you study, the app takes photos of your hands at unpredictable times. Not knowing "when you'll be caught" keeps you honest. That exam-room focus can happen at home too. 2. Team & friend sharing — getting caught keeps you accountable Your photos are shared with your team and friends. The feeling of "being watched" is a stronger deterrent than any amount of willpower. When you do well, the same visibility becomes your biggest boost. 3. Photo log — proof of your effort More than a time log. Your study moments stack up as photos. Seeing how much you've actually done multiplies your sense of achievement. ■ Who it's for ・Exam takers & students — You want to focus at home and get results. ・Professionals studying for certifications — You want gentle accountability without a real supervisor. ・Anyone trying to use their phone less — You want to cut mindless screen time and build self-control. ■ Results ・1.78x study time: Average weekly study time increased in prototype users. ・Better habits: Many users report sustained study routines. ■ Get started FocusSnap is free to start. Stop blaming yourself. Download now and get a new kind of focus. (*) Based on comparison of study time before and after use among prototype users.
