G-Spyke
BetaStratigraphic columns, layer by layer.
G-Spyke is a mobile app for building stratigraphic columns directly in the field. Instead of sketching sections on paper and redrawing them later, you log each layer on your phone as you measure it — and walk away from the outcrop with a finished, structured column.
G-Spyke is in beta and still being refined. Features may change as we improve the app with feedback from the field — your suggestions are welcome.
Made for fieldwork
Layer-by-layer logging
Record lithology, thickness, color and sedimentary structures for every unit as you move up section.
GPS geotagging
Pin every column and outcrop to its exact location so your sections are always traceable on the map.
Field photos
Attach photos from your camera or gallery to individual layers and keep visual context with your data.
Offline first
Everything works without signal. Your data is stored on your device — no account, no cloud required.
Your data stays yours
G-Spyke uses your location to geotag sections, your camera and gallery for field photos, and device storage to save your projects — everything you create stays on your phone, with no accounts and no ads. To keep the app stable we collect anonymous crash and usage diagnostics through Google Firebase; the details are in the privacy policy.
