SuperDictionary

A SuperDictionary for the Supernote community

I really wanted a native dictionary app, and was gutted when Supernote shelved the project. But for now, although it's far from perfect, I figured this app out. Because I'm also a user, I'll probably keep maintaining this until an official dictionary arrives!

Please let me know what you think or if you'd like to see more features, such as multi-language support, and I will have a look at it.

New in v1.1: Favorite words and lookup history! Tap the star to save words, access them anytime from the menu.

Tip: Add the app to your sidebar quick access for faster lookups while reading!

Features

Installation (Sideloading)

Supernote requires sideloading via ADB to install third-party apps. Here's how:

Step 1: Enable Sideloading on Supernote

On your Supernote, go to Settings > Security and Privacy and toggle Sideloading to "on".

Step 2: Install ADB on Your Computer

Step 3: Connect & Install

  1. Connect Supernote to your computer via USB cable
  2. Open Terminal (Mac/Linux) or Command Prompt (Windows)
  3. Verify connection: adb devices (should show your device)
  4. Install the app: adb install /path/to/supernote-dictionary.apk
  5. Launch the app on your Supernote and download the WordNet dictionary (~65MB)
Tip: Use the original Supernote USB cable for best results. If adb devices shows nothing, try adb kill-server then adb devices again.
