What is one-punch-fitness?

One Punch Fitness is a mobile workout app inspired by the anime "One Punch Man", the show about a hero who gets incredibly strong through a simple training routine. This app brings that concept to life by letting you track and complete workouts on your phone, with a gamified feel that makes fitness feel more like a fun challenge than a chore. The app gives you a straightforward way to log your exercises, time your workout sessions, and see your progress over time through a calendar view. You can set up your own routine, start a workout, use built-in timers to keep yourself on pace, and watch your completed workouts stack up on a visual calendar. There's also a settings screen so you can customize how the app works for you. It's the kind of tool you'd use every day if you're trying to build a consistent exercise habit, something you can pull out between sets or at the start of your day to stay motivated. The app is available right now through Expo, which means you can download it directly to your phone without needing to go through the traditional app store approval process. The team built this using React (a popular framework for building apps), styled it with modern design tools like Figma, and made it work across both iOS and Android phones. The codebase is written in OCaml, a programming language that emphasizes correctness and reliability, which helps keep the app stable as it grows. Anyone who wants to start or maintain a workout routine would find this useful, whether you're following the One Punch Man meme routine (100 push-ups, 100 sit-ups, 100 squats, and a 10-km run) or building your own custom program. It's lightweight enough to use without friction, but structured enough to help you actually track progress and stay accountable.
