About this app

The Stump mobile application is a companion app to the larger Stump software suite with support for other OPDS-compliant media servers. Tailored for on-the-go access, the app provides a user-friendly interface to browse, search, and read your digital book collection.

- Available on both iOS and Android devices, open source and built with React Native
- Download your content for later to read even when you're offline
- Automatically sync your reading progress to your Stump server and across all your devices
- Browse any compatible OPDS catalog to stream and download your content
- Permissions managed by the server are enforced in the app
- Available in multiple languages, with more translations coming soon

The app is in its early stages of development, and we are actively working on adding new features and improving the user experience. Stump is a community-driven project. The best way to improve the software is to hear and act on your feedback!
