Ollama Server
No need for Termux, you can start the Ollama service
Ollama Server is a mobile-first solution that brings the full Ollama runtime experience to Android devices through a simplified, one-click deployment model. Instead of relying on terminal environments like Termux, it provides a native application that launches and manages an Ollama-compatible service directly on a phone or tablet. The system exposes the same API behavior as standard Ollama installations, meaning any compatible client or integration can interact with it without modification. This makes it especially useful for developers who want to prototype or deploy local AI workflows on mobile hardware while maintaining compatibility with existing tooling. The application includes basic model lifecycle management such as downloading official models, uploading custom GGUF files, and controlling running instances. It also enables offline inference, allowing users to run language models entirely on-device without requiring a network connection or external infrastructure. -

ePUBator
Minimal offline PDF to ePUB converter for Android
Minimal offline PDF to ePUB converter for Android - ©2011 Ezio Querini ePUBator extract text from a PDF file and put it in a well formed (epubcheck compliant) ePUB file. PDF extraction based on iText library <http://itextpdf.com/> released under the AGPL license. - ePUBator IS THINKED FOR BOOKS (NOT FOR EVERY TYPE OF PDF), BUT IF YOU NEED A BETTER RESULT TRY SOMETHING ELSE LIKE CALIBRE. - ePUBator doesn't need internet connection (doesn't send your docs somewhere on the net, doesn't have ads). - ePUBator extracts text (no text from pictures or from raster PDF). - ePUBator tries to extract images (only png, jpg and gif) but puts them at the page's end. - ePUBator tries to extract the table of contents if present (or creates a dummy TOC). - ePUBator doesn't extract the font size and style and works fine only with single column PDF (worse with multi column or tables). -
