Hey there! I'm Schafer, the developer behind FlashFocus. I've been a full-time Android developer for the past 5 years, building mobile apps that are fast, clean, and genuinely useful.
FlashFocus started as a personal project. I wanted a flashcard app that actually felt good to use and worked offline. It's grown into something I'm really proud of, and I'm constantly adding new features and language sets.
I'm a Texas Tech grad (Wreck 'em!), a lifelong car enthusiast, and the kind of developer who obsesses over the small details, smooth animations, clean architecture, and thoughtful UX.
