Carta
Smart Digital Measuring Wheel
Your standard wheel counts steps. Carta maps your job, calculates the estimate, and gets you out the door — before your competition finishes scribbling on a clipboard.
Live measurement data — area, perimeter, dimensions — all on your phone as you walk the site.
Your Job Site,
Mapped in Minutes
Traditional measuring wheels tell you one thing: distance. Carta tells you everything. It's a full digital mapping system that lives in your pocket and connects to the Carta wheel via Bluetooth — giving you a live, accurate digital map of any outdoor space as you walk it.
Trace curved lawns, freeform pool decks, irregular lot lines, or complex irrigation zones. Carta captures every contour and immediately calculates square footage, cubic yards, perimeter, volume — and lets you build a full estimate right there in the field.
Built for the Field.
Not the Classroom.
Every feature was designed for one purpose: help contractors work faster, waste less, and win more jobs.
Walk the perimeter of any space and watch your job site appear on your phone in real time. Carta captures every curve and corner — no guessing, no re-measuring. Irregular shapes that used to take 20 minutes to estimate now take 2.
Core FeatureOverordering materials on curved or irregular jobs kills your margins. Carta gives you precise area measurements for complex shapes — so you order exactly what you need. Less waste. Better bids. More profit per job.
Save MoneyCarta's built-in estimator turns measurements into money. Calculate square footage, cubic yards, material costs, and full job quotes — all from the app, while you're still standing on the site. Close jobs faster.
Close Jobs On-SiteMark a valve box, termite trap, or underground utility and Carta will guide you back to it — even weeks later. The app shows you exactly where you are relative to the marked point and confirms when you've arrived.
NavigationSend your project data in five formats: JPG, DXF (CAD-ready), CSV (spreadsheet), PDF (client-ready), or Plott File. Share with your crew, email a quote to a client, or import into your accounting software. Done before you leave the driveway.
5 Export FormatsThe free Plott app pairs with Carta over Bluetooth in seconds. Available for iOS and Android. Take notes, mark POIs, add project photos, and manage your job history — all in one place. Setup takes less than five minutes.

Stop Leaving Money
on the Table
These aren't edge cases. They happen on every job. Here's what Carta actually fixes.
You measured 1,200 sq ft for that curved lawn. You ordered for 1,200. Job was actually 940. That's $400 in sod sitting in a dumpster. Carta measures exact irregular shapes so you order what you need — nothing more.
Client wants to change the scope. You drive back out to re-measure. That's 45 minutes you're not billing for. With Carta, every job is already in the app — pull it up, modify, re-export. Done in 2 minutes.
Valve box is in here somewhere. You marked it with a flag last week — flag's gone now. Carta's Guide Mode takes you back to any marked point with GPS precision. No more digging blind.
From Jobsite to Quote
in Four Steps
Carta eliminates the back-and-forth between measuring, calculating, and estimating. It all happens in one walk-through.
Connect Carta to the free Plott app via Bluetooth. Takes under 60 seconds. Open a new project and you're ready.
Roll Carta along the perimeter. The app builds a live digital map in real time — curves, corners, and all.
Close the shape and Carta instantly calculates area, perimeter, cubic yards, and material cost estimates.
Send a PDF quote, share a DXF with your designer, or export CSV data — before you leave the driveway.
Every Job It Handles
From residential landscaping to large commercial sites, Carta works wherever a traditional wheel falls short.
Measure curved lawns and garden beds. Calculate sod, mulch, and seed by exact area.
Mark valve boxes. Map zone coverage. Guide crews back to buried components weeks later.
Calculate freeform concrete pours, pavers, and retaining wall footprints precisely.
Measure perimeter runs with corners and offsets. Get accurate linear footage instantly.
Eliminate the guesswork on irregular shapes. Order exactly what you need — no waste.
Map complex curved shapes around pools and structures that no measuring tape can handle.
Calculate cut/fill volumes and area quickly. Share data with engineers via DXF or CSV.
Map large commercial lots. Calculate paint and materials. Export maps for striping crews.
