Amazing. A few nerdy med students and I started a student group for tech back in 2009 or so, a big part early on was preaching Mnemosyne (another SRS app), with shared decks syncing over a free Dropbox account.
Later used Repetitions (iOS / Mac / web) for the steps, EM boards, and informatics boards most recently.
Only within the last year finally tried Anki -- and this time for language.
