The best
I have tried variety of Language Apps including Duolingo or less popular ones but none of them where actually good. You had to pay to get any usefull function or the App wasn’t teaching and you had no Progress in Language. My friend recommended Tobo App and i gave it a Chance. It Is COMPLETELY free. You can pay to get rid of adds but it isn’t nessesery. You have Access to whe whole App - 70 Charters and Games to each one. You can categorise vocabulary based on a difficulty Level and practise it as flashcards. It Is the best vocabulary App i have used.
