Spaced repetition for developers: see FlashCode's typing-based active recall in action

What makes it work

Everything FlashCode does is designed around one outcome:syntax that stays when you need it.

Core mechanic

Active recall coding

You type real code from memory. No hints, no copy-paste. The resistance is the point: retrieval builds muscle memory that reading never will.

// Reverse a linked list in Python

Scheduling

Spaced repetition

SM-2 surfaces each snippet exactly when you're about to forget it. Five minutes a day compounds into syntax that sticks permanently.

Pro feature

GitHub importPRO

Turn any public repo into a study deck. FlashCode pulls the patterns worth remembering so you train on real production code, not tutorial examples.
