How It Works
Built to be simple
Take a photo of your sensitive paper, wait a few seconds and that's it: your analysis and report are ready. Just review them.
Reports
From photo to report, in seconds
Every analysis becomes a complete report, ready to send to your client on WhatsApp, hand to the technical team or keep in the field's history.
Automatic AI diagnosis
Spraydex AI interprets the results and writes a clear assessment of uniformity, drift and what to adjust on the next application.
Industry-standard metrics
DV10, VMD, DV90, span and density — with a per-class histogram separating fine, ideal and coarse droplets.
Side-by-side report between papers New
Place two or more papers side by side in a single report and compare coverage, density and VMD head to head — to see instantly which nozzle, setting or condition delivered the best application.

Frequently asked
Frequently asked questions
What growers and applicators most often ask before getting started with Spraydex.
What is Spraydex and how does it work?
Spraydex turns your phone into a spray analysis tool. You take a photo of the water-sensitive paper, our AI processes the image and, in seconds, returns a complete report with the application's metrics — without any extra equipment.
Do I need to buy a microscope or any equipment?
No. The analysis is done right on the phone you already have in hand. No separate hardware to buy, carry, pair or calibrate before every use.
Is analysis with a phone reliable?
Yes. We compared Spraydex side by side with professional microscopes across dozens of samples and the results were practically identical. You can check the numbers on our tests page.
What information appears in the report?
Every analysis becomes a report with industry-standard metrics — DV10, VMD, DV90, span and density —, a per-class histogram (fine, ideal and coarse droplets), an assessment of uniformity, overlap and drift risk, plus an automatic assessment written by Spraydex AI.
Does it work on my phone?
It works on iPhone and Android. Just download the app from the App Store or Google Play and take your first photo.
Does it work for spray drones?
Yes — it's one of the most common uses of Spraydex. Evaluate effective swath, coverage and drift risk for every flight, compare settings between flights and keep a history of your applications — the records regulators (in Brazil, MAPA Ordinance 298) require operators to retain for 2 years.
Can I export and share the reports?
Yes. Every report can be exported as a PDF and shared directly with the client or technical team. Everything is saved in your history, organized by field and equipment.
How much does it cost and is there a lock-in?
During the Pre-Season Sale: R$ 139/month or R$ 1.099/year — which works out to R$ 91,58/month (after the sale: R$ 179 and R$ 1.499). Unlimited analyses, no per-user license and no lock-in: subscribe and cancel whenever you want. And before subscribing, you get 3 free analyses.
How do the 3 free analyses work?
You download the app and run up to 3 complete analyses for free — no credit card, no expiry date. Nothing turns into a charge on its own: you only pay if you decide to subscribe.
