Tool to memorise and practice new vocabulary

Hey, I'm looking for a solution that would help me with my foreign vocabulary learning routine: 1. Note down vocabulary during my lessons + its meaning 2. Memorise/practice it twice a week to remember 3. Nice to have: be able to tag specific phrases, for example: useful for discussion, economic vocabulary, computer-related etc. So far I've been: - adding new words to a Quizlet set - practising it twice a week on Quizlet Quizlet has its ups (suggesting translations) and downs (super bloated UI). But it's nowhere near the "tagging" part. Can You recommend any better solution? :-)
