Geòlas is a field notebook for geologists covering Great Britain: log a site with GPS, get bedrock and superficial geology from the British Geological Survey, and keep photos, samples and notes synced privately through your own iCloud.

Where are my sites kept? On your device, in the app’s own storage — and, if you’re signed in to iCloud, in your own iCloud account too, so your devices share one library. There’s no Geòlas account and no Geòlas server. See the privacy policy.
Why is there no geology data for my site? Bedrock and superficial geology lookups currently only cover Great Britain (England, Scotland and Wales). You can still log a site anywhere — you just won’t get an automatic geology lookup outside that coverage.
Some of my sites are grouped under the wrong region — why? Region grouping for your own sites is inferred from location bands, and it isn’t perfect at a few boundaries. The curated reference sites always show their correct region regardless.
How do I get my sites off the app? Settings has a JSON and GeoJSON export you can share out through the usual share sheet.
Can I use it on my Mac as well as my phone? Yes — it runs on the Mac through Catalyst. It’s the same app, not a separate one, and it’s the same iCloud sync.
Will my sites be on all my devices? Yes, if you’re signed in to iCloud on each device with the same Apple Account. It syncs through your own iCloud account, not through any server of mine — see the privacy policy.
