Summary
Everyone studying Chinese should download Pleco on their phone. It’s easily the best dictionary app available, but it can do so much more than just help you look up the meanings of words. The core features are free to use, but there are a number of add-ons (some paid) which makes it even more useful. Some of these are SRS flashcards, OCR which lets you look up words using your camera, audio recordings, document reader, screen reader, handwriting recognition, and more. This is the one app that pretty much everyone agrees is a must-have.
