GrammarLens
Most grammar tools tell you a sentence is wrong and hand you a correction. GrammarLens tells you which rule you broke and why the correct version works — so the next sentence is easier.
The app is finished and being prepared for App Store review. There's nothing to download yet.
Explains, not just corrects
You write or paste a sentence. GrammarLens identifies the mistake, names the rule behind it, and shows a corrected version alongside a short explanation of the difference.
Practice that adapts to your time
You choose how long a practice set should be. A short set when you have five minutes, a longer one when you don't.
Your work stays on your phone
Practice history is stored locally on your device, not on a server. Full privacy policy.
People who already speak some English and keep making the same handful of mistakes — usually articles, tenses, and prepositions. If you're starting from zero, a course will serve you better than this app.
