Pebble Flashcards

This is a learning project in order to create a simple Pebble app, which displays (text-based) flashcards and collects interactive feedback. The feedback is evaluated with python and a new set of questions is prepared.

The Pebble app works without a smartphone. The data is exchanged with a pc. Necessary functions for this exchange can be found in pebble-pc-communication-example.
