A focused flashcard app for Chinese, Japanese, Hindi and Urdu. Built for short sessions, long streaks, and zero account friction. Works offline.
The biggest visual update since launch. New icon, new indigo theme, picture-in-picture study, and the small details that make a daily habit stick.
A redesigned card-stack mark and a deep indigo palette pulled across every screen — softer on long sessions, easier on the eyes.
A new dialog explains exactly how your streak is calculated, so you always know where you stand for the day.
Keep a card floating while you switch apps. Quick reviews between the rest of your day.
Pronunciation visibility, audio, and study mode now persist between sessions. Set it once.

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, a lifelong car enthusiast, and the kind of developer who obsesses over the small details — smooth animations, clean architecture, and thoughtful UX.
