Terramark for iPhone & iPad

Built on iOS,
tuned for the field.

Terramark uses Apple's native camera and location frameworks directly — AVFoundation for capture, Core Location for best-accuracy GPS — so photos are ready the moment you stop shooting.

Also available on Android

Native iOS

Built directly on Apple's frameworks, not a cross-platform wrapper.

📷

Native Capture Quality

AVCapturePhotoOutput at full resolution, with correct orientation even when your device's rotation lock is on — a common weak spot in competing apps.

📍

Best-Accuracy Location

Core Location's highest accuracy mode, with every record's ±m horizontal accuracy stamped and visible — not hidden in metadata.

🧭

True Heading Compass

Uses CLHeading's true heading when available, with a clear ≈ warning if it falls back to magnetic heading.

🗂️

GPS EXIF Everywhere

Every photo — stamped and raw — gets GPS EXIF written via Core Graphics, readable by Photos, Finder and any GIS tool that reads EXIF.

Questions iOS users ask

Which iPhones and iPads does Terramark support?

iOS 17 and later, on iPhone and iPad.

Does Terramark need an internet connection to take photos?

No — capture is fully offline. Only reverse-geocoding the address needs a connection, and that happens automatically later if you're offline when you shoot.

Does Terramark work correctly with the rotation lock on?

Yes — photo orientation is corrected at capture time using the device's motion data, not just the interface rotation lock, which is a common weak spot in other camera apps.
