Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 2.8 MB, so it installs quickly even on modest connections.
This build is signed by "F-Droid Open Source" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

OSS‑Dict is a fast, privacy-friendly offline dictionary reader — a modern fork of Aard 2 with Material design and enhanced features for comfortable reading and lookup.

Highlights

* Blazing fast searches: punctuation, diacritics and case insensitive — find entries instantly.
* Bookmarks & history: save and revisit important articles quickly.
* Dictionary management: import, enable/disable and organize multiple dictionary files.
* Customizable article appearance: add your own CSS to change fonts, colors and layout.
* Beautiful math rendering: scalable, styleable formulas that look great on any screen.
* Random article for discovery, volume-button navigation, and fullscreen reading mode.
* Clipboard auto-paste and easy external link sharing for fast lookups from other apps.

Why OSS‑Dict? OSS‑Dict is designed to work entirely offline — your dictionaries stay on your device for fast lookups and better privacy. It’s lightweight, configurable, and ideal for travelers, students, and anyone who needs reliable dictionary access without an internet connection.

Network access The app requests the INTERNET permission for internal use by the built-in renderer and to open external links. This permission is not required for core dictionary lookups — the app functions offline with local dictionary files.

Open source OSS‑Dict is open source and available on GitHub. Contributions, bug reports and feature requests are welcome.

Get started Install or import your offline dictionaries, customize the look with CSS if you like, and start searching — fast and offline.

Frequently Asked Questions

Is OSS-Dict free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does OSS-Dict require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is OSS-Dict safe to install?
We link to the exact APK published by F-Droid Open Source. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update OSS-Dict?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.
