Transcript
Opening a spreadsheet on your phone usually means uploading it somewhere. Gander renders everything on the device with zero permissions and no internet access at all. PDF, Word, Excel, PowerPoint, photos, video, audio, Markdown and code all open in one app, searchable, with pinch zoom everywhere. A file shared from any app opens right in it, never leaving the device.
