How we rank
We rank apps by who they genuinely suit, what they cost, and how much they help with the skill learners neglect most: understanding real spoken French. Every price and fact was checked on the product's own site or app store listing on the date shown; where a price is not shown publicly we say "see site". Nobody pays to be listed or ranked, and there are no affiliate links. More about this site.
Questions

KwizIQ, because its quizzes adapt to find what you get wrong; Lawless French if you want the rule explained clearly in English, for free.
Is there a free French grammar website?
Lawless French is free, and Bonjour de France and Le Point du FLE have free exercises written in French, which suits learners from about B1.
Do I need to study grammar to speak French?
Some, yes. A little grammar every day makes your listening and speaking more accurate, but it does not replace them.
