Plot list and offline map
The field app shows the day’s plots with farmer name, size and distance. A map of the area is saved on the phone for use without signal.

Verdacount: Carbon MRV Platform for Tree Planting
Verdacount is a platform designed and built by our team for measuring, reporting and verifying the carbon stored by trees that small farmers plant. Surveyors measure trees in a phone app and the project team gets numbers an auditor can check.

The brief
What a tree-planting project needs
Small farmers plant trees on plots of less than a hectare. A project may cover thousands of them across many villages, and each tree grows slowly over many years.
To show the project is real, someone has to measure the trees, keep the records and let an outsider check them. On paper this is slow, easy to get wrong and hard to repeat each year.
-
1
Measuring in the field
Surveyors need a simple phone app that works without signal and records species, size, health, place and a photo.
-
2
A clear map of plots
The team needs to see every plot, who owns it and when it was last visited.
-
3
Numbers that can be explained
Each carbon estimate should trace back to trees, formulas and photos, not to a single number in a sheet.

A pack for the auditor
An independent checker needs the evidence in one place and a way to pick and re-visit a sample.
What we designed
Inside Verdacount
We designed Verdacount as two parts: a field app for surveyors and a web platform for the project team and the auditor. Both use the same plot and tree records.
Tree measuring
For each sample tree, the surveyor picks the species, sets the girth, marks health and takes a photo. The app stamps the photo with time and place.
Sync
The Sync screen shows what is waiting on the phone and what has reached the office, so nothing is left behind by mistake.
Project map and totals
The web platform shows plots on a map, trees counted, share alive and an estimate of carbon stored. Plots that need a re-visit show in amber.
Carbon estimate
The platform works out an estimate from measured trees with the formula you set. It shows the inputs, so the figure can be traced.
Verification pack
For the auditor, each plot shows its count, size, photo and checks. Odd counts are flagged, a sample can be chosen and the numbers for a plot can be held until it is re-visited.

How Verdacount looks
The mobile app
How it works
Key journeys, step by step
Here is how the main tasks run on the platform.
Visit a plot
The surveyor opens the plot, walks to a sample of trees and records each one. The data stays on the phone until there is signal.
Sync the day
Back in range, the surveyor taps Send. The office sees new trees, photos and places within minutes.
Spot a problem
The platform flags a plot where the live count is far below what the farmer planted, and sets it for a re-visit.
Hand over to the auditor
The team sends a pack for the year. The auditor picks a sample, checks it against photos and signs off.

FAQ
Questions about building a product like Verdacount
What does MRV mean?
MRV stands for measure, report and verify. It means counting what a project has done, such as trees planted and kept alive, writing it down in a clear report and letting an independent person check it.
How long does it take to build a carbon MRV platform?
It depends on the measuring method your standard asks for, how many tree species and formulas you need, offline map needs and the reports your auditor wants. A first release with the field app, plot map and sync can come first.
Can you build a carbon measuring platform like this for my business?
Yes. We can build a field app for Android and iOS and a web platform for your project team, using the measuring method and formulas your standard or auditor requires.
Where do the carbon numbers in the screens come from?
The screens use sample figures to show where an estimate appears. A real project must use the formulas and tree data that its chosen standard asks for, and the platform runs whichever formula you set.
Does the field app work without internet?
Yes. In the design, plots, maps and forms are saved on the phone. Measurements and photos are stored there and sent when the surveyor has signal.
How does the platform help an auditor?
It puts each plot’s count, size, photo, place and time in one pack. The auditor can pick a sample of plots, see how each number was made and note what was re-visited.
