Gonja
Disk Space Visualizer
Free
See where your space went. Pick a folder in Files, from iCloud Drive to a USB drive, and Gonja maps it into a clear, explorable picture. No account, no network access.
See where your space went.
Gonja turns any folder into a picture you can actually read. Large files and folders become large areas; small ones become small. One glance tells you what is taking the room, and a tap takes you inside it.
Pick a folder in Files
Choose any folder you can reach in Files: iCloud Drive, On My iPhone or iPad, a USB drive, or a server. Gonja reads nothing until you choose. Pin a folder as a favorite and scan it again later without the picker.
A map you can explore
The visual map sizes every rectangle in proportion to what it holds. Tap to select, tap again to zoom in, and follow the breadcrumbs back out. Long-press anything for its actions. Colour the map by category, by folder, by age, or by a plain monochrome scale; every category carries its own symbol too, so the map still reads if colour is hard to distinguish. Folders take the colour of what they mostly contain, so the first screen already shows where the video, photos, and archives are.
A list when you want detail
Switch to the list for every item's size, size on disk, share of the scan, and kind, with a bar that shows its share at a glance. On iPad the list becomes a full table with sortable columns. Search or filter instantly: filtering never re-reads your files.
Honest numbers
Two sizes are correct at the same time, and Gonja shows either: the apparent length of a file, or the space it actually occupies. Links are never followed. Files reachable under several names are counted once. Packages are measured all the way through but shown as single items. When a folder cannot be read, Gonja says so and reports what it skipped instead of pretending it measured everything.
Nothing leaves your device
No account, no analytics, no advertising, no tracking, and no connection to anything. Gonja reads only the folder you picked, and only file metadata: never the contents of your files.
Careful with your files
Gonja cannot delete anything permanently. Moving items to the Trash always takes an explicit confirmation that lists every affected item by name and size. Where the location supports it, items go to Recently Deleted in Files; locations without a Trash are left untouched.
Made for iPhone and iPad
The inspector shows every detail of a selected item: as a sheet on iPhone, beside the map on iPad. Quick Look previews, Share, Show in Files, and Copy Path are a tap away. Export any scan as CSV or JSON. Light and Dark appearances, VoiceOver support, hardware keyboard shortcuts on iPad, and Reduce Motion, Increase Contrast, and Reduce Transparency all respected.
Gonja does not clean, optimize, speed up, or diagnose your device. It measures, and it shows you what it measured.
