Features
Everything you need for forest surveys
The forester's toolbox, integrated in a smartphone: field visits that rely on the iPhone's sensors (GPS, camera, microphone, compass, LiDAR) and work without network coverage.
Mapping & GPS tracks
Record your GPS tracks, draw your parcels, and export everything in a format compatible with GIS software.
Geolocated observations
Points and routes — every record is located and automatically attached to an estate or a parcel.
Detailed inventory
Species, stage, diameter, height, quality… structured, usable records, ready to export.
Basal area with the relascope
Measure basal area with the built-in relascope and instantly get the statistics of your parcels' records.
Photographs for the record
Keep a visual memory of your observations and compare two visits side by side.
Voice notes
Dictate your notes: transcription happens automatically on the device, hands-free and offline.
Compass & bearing
Horizontal and vertical compass; set a bearing and follow it to lay out your cleaning strips.
LiDAR measurement
Measure distances and heights with LiDAR, on compatible devices.
Explanatory guides
Get started with the app
One guide per module: what you see on screen, in the order you will use it in the field.
Getting started
First steps, the active domain, automatic filing of your observations, and your credits.
Domains

Mapping
Record a boundary by walking it, or draw a plot by hand on satellite imagery.
Observations
The field notebook: photographs, voice notes, tree inventories, basal area, soil description.

Privacy
Your data stays on your device
Forest Assist runs entirely on your device: no data is collected, no server, no tracking, no account. Your records only leave the device if you decide to export or share them. Learn more: Privacy policy.
No data collection
No account, no server, no analytics, no advertising. Nothing is sent to third parties.
Data used locally
Location, photos, microphone and contacts are used only for the features, on the device.
You stay in control
Exports (KML, e-mail, iOS sharing) only happen when you trigger them.
