About this app

Every sentence in Gaffe has one small mistake, or none at all. Find it, tap it, and choose the right fix.

The mistakes are the ones English learners really make, and plenty of native speakers too: a verb that doesn't agree, a missing article, less instead of fewer, its instead of it's, a word that is almost right.

HOW IT WORKS
Tap the word that is wrong, then pick the correction from a few options. If you think the sentence is fine, say so: about one sentence in six has no mistake at all, so guessing doesn't pay. Every answer comes with a short, plain explanation.

IT GROWS WITH YOU
The sentences get harder as you get better, from everyday slips to mistakes that catch out careful native writers. Every round of ten is a mix.

WHAT YOU WORK ON
- Verb agreement and tenses
- Articles and prepositions
- Countable and uncountable nouns
- Word order and questions
- Commonly confused words
- Spelling that trips people up
