Great extension for an absolutely amazing product! I use buboflash daily and for me it is an essential tool in helping learn new materiel fast and retain the knowledge long-term. I also want to give special praise to Piotr Wasik, for putting so much time and effort into buboflash. He not only has put out a great, free tool for learning, but does a superb job maintaining it. I recently found a bug with buboflash (extremely rare occurrence) and after emailing Piotr, he put out a fix within an hour or so. Absolutely amazing! Even the top paid products don't provide this level of support and maintenance. Thank you Piotr and keep up the great work.
Excellent app to collect, review and internalize information.
Incredible app for productivity and accelerated learning... better than any of the popular spaced repetition programs out there, including Supermemo and Anki. I love the ease of use, and its use of incremental reading.
