Build your vocabulary by saving words important to you. Test yourself daily to memorise them.

Practice with your friends regardless of what language they're learning or what level they're at.
"I've used a lot of different language apps... but Sylvi has been the one I've been having the most success with growth-wise. At least from what my tutor tells me."

"I know grammar. I know all of these vocabularies, but you're kind of stuck in the middle of like - how do I become comprehensible? Then I found Sylvi" - Amira, UK
"I could say, 'I'm going to the cinema today'. Then if I do Sylvi tomorrow, my penpal will come back and say, 'so what film did you see at the cinema?'. I love the continuity. It's so clever." - James, US
