Crownwise: Tree Risk Reports

Crownwise is a field tool for qualified tree risk assessors. Record a Level 2 assessment on site, and leave with the report already written.

WRITTEN ON SITE, NOT AT THE KITCHEN TABLE

A Level 2 assessment is thirty minutes of looking and two hours of typing. Crownwise removes the second part. You record each tree, judge the parts and targets you can see, and the report assembles itself as you go.

HOW IT WORKS

1. Start an assessment with the client, site and scope.
2. Add each tree: species, DBH, height, location, site conditions, health and structure, and anything that limited the inspection.
3. For every part that could fail, record its size, fall distance and load, then the target it could strike, the target zone, how often that zone is occupied and what protects the target. Judge the three inputs: likelihood of failure, likelihood of impacting the target, consequences of failure.
4. The rating appears immediately, with the matrix on screen so you can see where it came from.
5. Record the recommended work, the residual risk after it and when to reassess. Generate the report and send it before you get back to the truck.

THE REPORT

• Your letterhead: name, credentials, certification number and expiry
• Your signature, drawn once and printed on every report
• A summary table of every tree with its overall rating
• Per part: size, fall distance, load, target zone, occupancy and protection, the three inputs, the derived rating, and the matrix reproduced with your cell marked
• Whether the data is final or preliminary, and any advanced assessment you recommend
• Recommended work, timeframe, residual risk and reassessment interval
• Assumptions and limiting conditions

The failure, target and follow-up fields match the 2025 basic tree risk assessment form. A rating whose derivation is invisible is not defensible. Crownwise prints the working.

WORKS WHERE YOU WORK

Once Crownwise Pro is active, no signal is needed. Nothing in the assessment needs a connection — not the matrix, not the photographs, not the report. Under canopy, in a basement car park, on a rural verge: it behaves the same. Buying needs a connection once.

YOUR DATA STAYS YOURS

No account. No sign-up. No analytics. Everything you record stays on your device, and the only thing that ever leaves is the report you choose to share. There is no server holding your assessments; the app only checks your purchase with the App Store, through RevenueCat.

PHOTOGRAPHS ATTACHED TO FINDINGS

The camera opens from inside the row you are recording, and the photograph is attached there and then. No matching a camera roll to findings afterwards.

WHAT CROWNWISE IS NOT

Crownwise does not perform tree risk assessment and does not give arboricultural advice. Every input is selected by you. The app applies published matrices to those inputs and assembles the result. The professional opinion in any report is yours, and you are responsible for it. It is a tool in the same sense that a calculator is a tool.

Crownwise is an independent product. It is not affiliated with, endorsed by, sponsored by or certified by any professional body, standards organisation or certifying authority.

CROWNWISE PRO

Starting an assessment and generating a report require Crownwise Pro: a monthly subscription, or a single Lifetime purchase. Assessments already on your device stay readable without it.

The monthly subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period. Manage or cancel it in your Apple ID settings. Lifetime is a single payment and does not renew.
