Our verdict on Gander

Gander is an open-source Android file viewer for people who want to open documents and media locally without accounts or internet access. It covers office files, PDFs, images, video, audio, Markdown, plain text and source code, including PDF, DOCX, XLS/XLSX-family and PPTX rendering. Its privacy-focused design also avoids permissions and analytics, while Android 8.0 and newer provides the documented platform range.

For everyday file access, Gander combines folder browsing through Android system file grants with recent files and thumbnail previews. Open-with and share-sheet integration help it fit into Android’s existing file workflow, while text selection and copying in PDFs add practical utility. Search works within PDFs, Word, Excel, slides, Markdown, text and code, making the app more useful than a viewer limited to opening files. PDF night mode is also included for reading in darker environments.

Gander is a focused choice for Android users who prioritize local viewing, privacy and broad format coverage over cloud features or cross-platform access. Distribution is through APK releases from GitHub, with Google Play described as forthcoming. It should suit people who need a lightweight viewer for mixed office, media and developer files on an Android device. Users seeking desktop or iOS coverage, account-based access, cloud synchronization or AI features should choose a different tool.
