About this app

QST Office is a complete office suite for your phone. Write documents, build spreadsheets, design presentations and edit PDFs, all offline and all on your device. Open and save Word (.docx), Excel (.xlsx) and PowerPoint (.pptx) files, and export any work to PDF.

Your files stay on your phone. QST Office never uploads your documents, so it works on a train, in a village with no signal, or in an exam hall.

Every feature is included, with nothing to buy. Editing time comes from reward points that you earn by watching short videos, and ads keep the app free. No ad is ever shown while you are editing.
