Stop typing tree data twice.
LogLog replaces the clipboard-and-spreadsheet shuffle. Mark trees on your site plan, record species and DBH, snap photos — export the report. All from your phone.
The tree survey workflow is broken.
The old way
Print the site plan, mark it up by hand. Then photograph the markup. Then hope you can read your handwriting later.
With LogLog
Tap to place trees on your actual site plan. No printing, no hand-marking, no squinting later.
The old way
Type everything into a spreadsheet after. Back at the office, squinting at field notes, entering DBH measurements row by row.
With LogLog
Enter it once, on site. Species, DBH, condition — done. Walk away. That tree is finished.
The old way
Photos in one place, data in another. Camera roll full of tree photos. Which one was tree #14? Who remembers.
With LogLog
Photos attach to their tree. Always linked. Always findable.
Built for the field.
Mark up any PDF site plan
Load your site plan. Tap to drop tree markers. Each pin becomes a full record — species, DBH, condition, photos, notes. No printing, no hand-marking, no re-typing.
Works offline. Syncs when you're ready.
No cell signal on site? No problem. LogLog stores everything on your device. Data syncs when you're back online.
Export what your client needs.
ZIP with spreadsheet, annotated site plan, and all photos. Ready for the client in one tap. Excel, CSV — whatever they want.
Built by an arborist, for arborists.
I got tired of typing the same tree data twice. After years of printing site plans, hand-marking trees, and then spending evenings re-entering everything into spreadsheets, I built the tool I wished existed.
LogLog started as a personal project to fix my own workflow. It turned into something I think every arborist who does tree surveys should have. No more clipboard shuffle. No more disconnected photos. Just survey, record, export, done.
