Helps you see before you spend money from higher resolution commercial vendors. Many thanks to @SoarAtlas for the inspiration. Will be rolling out more improvements over the next week or two.

NDVI Scope

NDVI Scope

Find your farm, search clear Sentinel-2 dates, compute NDVI and problem areas on your phone, and share a KMZ. No account and no Marshall Frith backend.

iOS · TestFlight · Support & product page

NDVI Scope helps you outline a field, search the public Element84 Sentinel-2 L2A catalog, compute NDVI and scout problem patches on the device, and export a KMZ for Earth / ATAK-style tools.

What it does

  • Address or coordinates first (Apple Maps search / geocode; typed coordinates stay on device).
  • Draw or adjust a farm box on a MapKit map.
  • Search live sentinel-2-l2a scenes (no API key), download COG windows for red / NIR / SCL, compute NDVI and problem areas on the phone.
  • Save named fields on this phone; export / share a problem-area KMZ.

Privacy in one line

No account, sign-in, ads, or analytics SDK. Imagery and place search leave your device toward public Element84/AWS hosts and Apple Maps services; Marshall Frith does not run an NDVI Scope backend that stores your fields. Full policy: marshallfrith.com/ndviscope/privacy/.

Support

Questions or TestFlight feedback go through the contact form. Messages reach Marshall Frith directly.

Requirements

iPhone, iOS 18 or later. Internet required for place search (when not using raw coordinates) and for Sentinel-2 search / COG reads. Saved fields and KMZ exports stay on the device until you delete them or the App.
