About this app

Pleco is the ultimate Chinese learning companion - an integrated Chinese English dictionary / document reader / flashcard system with fullscreen handwriting input and live camera-based character lookups, from a company with 17 years' experience making mobile Chinese learning software.

Major features: ($ = paid add-on)

Great dictionaries: the free app comes with two dictionaries - CC-CEDICT and our in-house PLC dictionary - which together cover 130,000 Chinese words and include 20,000 example sentences with Pinyin. We offer 8 more free dictionaries as optional downloads, including a 22,000-entry Cantonese-English dictionary, and 19 other great dictionaries are available as paid upgrades. ($)

Handwriting input: lookup unknown characters by drawing them, with a best-in-class recognition engine. (basic version free, enhanced version $)

Live Optical Character Recognizer (OCR): look up Chinese words in the dictionary simply by pointing your device's camera at them, or by scrolling around a still image. ($)

Screen Reader/OCR: instantly tap-lookup Chinese words in other apps through a floating interface; works on Android 4.1 and later. (reader free, OCR $)

Flashcard System: create a card from any dictionary entry with a single button tap, import premade word lists, use advanced techniques like SRS (spaced repetition), and study in a variety of modes including fill-in-the-blanks and tone drills. (simple version free, full-featured $)

Audio Pronunciation: instantly hear male + female native-speaker audio for Chinese dictionary headwords; recordings available for over 34,000 words. (stitched-syllable free, multi-syllable $) Or listen to example sentences with text-to-speech (system TTS free, enhanced $).

Powerful search: look up words by Chinese characters, Pinyin (spaces/tones optional), or a combination, with support for wildcards and full-text search.

Cross-referencing: tap on any Chinese character / word in any dictionary entry to bring up its definition.

Stroke Order Diagrams: animations showing you how to draw each Chinese character; 500 in free app, 28,000 in paid add-on.

Voice Recognition: look up words by speaking them into your device's microphone.

Document Reader: open a Chinese-language text or PDF file and look up unknown words in the dictionary simply by tapping on them. ($) You can also look up characters on web pages through "Share" and in other documents through the clipboard. (free)

PRC- and Taiwan-friendly: supports traditional and simplified characters (in dictionary definitions, stroke order, search, OCR, and handwriting), and supports Zhuyin (with ruby support) as well as Pinyin for pronunciation display.

Cantonese: display headwords + perform searches in Jyutping/Yale romanization. We also offer Cantonese dictionary and Cantonese audio add-ons. (some $)

No ads: we won't even nag you about buying add-ons.

We also offer excellent customer support - send us an email and see for yourself - and an active user community at plecoforums.com.

We've been making Chinese dictionary apps since 2000, and our sales and customer base have been steadily growing for 17 years across four different platforms. We take good care of our longtime users: people who bought a dictionary on a Palm Pilot in 2001 can still use that dictionary on a new Android phone in 2020 without even paying an upgrade fee.

Paid add-ons can be moved to a new device like any other paid app; just open our free app on your new device and they should reactivate.

If you already own Pleco on another OS, see pleco.com/android for migration options.

This app uses Accessibility services. (for our Screen Reader feature, which helps users to get by in Chinese-speaking regions without knowing Chinese)

More than just a simple dictionary. Provides card system to review words and even lookup words on screen. The app is free with no ads with some add-ons costing money but they are completely optional. This app is a must if you're learning Chinese.

I regret paying any money for this. This app 100% needs to be sunsetted and replaced. The manual doesn't match the app, OCR can't read top-bottom and honestly can barely read a lot of single characters correctly, the flashcard system is a waste of time (just use anki), I can go on.

If you write support we'll be happy to set up a refund. If you'd like to dig into any of your specific issues by contacting support, we'd be happy to do so - this does not sound like a normal experience - but we can't do much for you in the 350 character limit of a review reply. (we are beta-testing a big revamp at the moment, but on iOS first)

I've been a Pleco user for more than a decade. The updated OCR is different, and after using it for a few weeks I can confidently say it's worse than before. Just the basic job of recognizing characters, it's gone from near 100% to barely usable.

Sorry about that; you can get the old OCR back with "Legacy OCR Interface" in Settings / OCR, or you can try our new experimental algorithm - which we plan to migrate to as the default in a year or two but is too slow for now - with "Experimental Still Algorithm." (the current algorithm is intended as a bridge between our 2009-era one and that)

What’s new

- Adopted new HWR + OCR libraries by default, including for live OCR, though you can revert to the old ones in settings
- Adopted better/streamlined "new OCR" interface by default for live OCR, though with the new algorithm it's a bit different (we show text above the box rather than as an overlay because ML text rects are less accurate)
- Added 'snap OCR' for quick captures of text to tap-lookup
- Switched to open-source PDF library and cleaned up some PDF reading annoyances
- Many bug fixes
