### 5/5 — Super helpful and easy to use

*2026-04-13*

Really impressed by how this app explains words. It’s not just definitions, it also breaks down usage, translations, and even gives extra context like how the word is used in real life or slang. The “more with AI” section is especially helpful and makes learning feel more intuitive. Clean interface, no distractions, and very easy to use. Definitely one of the better dictionary apps I’ve tried.
