Describe your project in plain words, get a plan, and walk into every inspection ready. Three tabs: Home, My Jobs, and Get Help.
Tap any tab in the bar at the bottom of the screen to get started.
One question starts everything.
The Home tab opens with a single question: What are you working on? Describe your project in your own words โ no forms, no jargon. You instantly get an answer card with permit guidance, your local inspection agency (with a booking link), and how many inspection points apply to your job.
How to use it
Example inputs that work
Home also has a Site Restrictions check โ enter your postal code to flag flood, heritage, or soil contamination zones before you commit to a project.
Everything for your job in one place.
Starting a project opens its workspace. Everything lives in collapsible sections: your step-by-step plan, the inspection checklist, project questions, inspection fixes, and notes. The header shows the project name, status, and progress counts so you always know where you stand.
How to use it
Use the Project Notes section for anything you'd otherwise scribble on a scrap of wood โ measurements, inspector comments, contractor phone numbers.
Your whole renovation, from planning to final inspection.
The workspace generates a construction roadmap tailored to your project and city โ every step from planning through rough-in to final inspection, with who does what (you vs. a licensed trade), when to book each inspection, and a materials list.
How to use it
Share the plan with your contractor before work starts โ it sets clear expectations about scope and inspection timing.
Everything ready before the inspector arrives.
Each project has its own code-referenced checklist of what the inspector will look for. Progress saves per project, so you can bounce between jobs without losing your place.
How to use it
Do the checklist walk-through the day before the inspection, not the morning of โ some fixes take longer than you think.
Plain-language answers that know your city and project.
Inside a project, the Ask about this project section answers code questions using your project's type and city automatically. For general questions without a project, use the Get Help tab. Answers show the codes in force for your city, and verified answers display green source citations from official sources.
How to use it
Example inputs that work
The more specific your question, the better the answer โ inside a project, the app fills in the project details for you.
Decode failed inspection notes and track the fixes.
Failed an inspection? Paste the inspector's note into the Fix an inspection issue section of your project. You get a plain-language explanation of what's wrong and how to fix it, and you can track each correction until re-inspection.
How to use it
Example inputs that work
In a hurry? The "Decode an inspection note" quick tool on Home does the same thing without opening a project โ and it accepts a photo of the notice.
Point your camera at the problem.
Two quick tools on Home work from photos. "Decode an inspection note" reads a photo of the inspector's notice. "Scan your space with photos" looks at pictures of your actual space and builds a photo-based plan โ which saves as a project.
How to use it
Good lighting and a few wide shots work better than many close-ups.
Every project you've saved, in one tab.
The My Jobs tab holds all your saved projects. Search or filter to find one, tap to reopen it with everything restored โ plan progress, checklist, saved answers, fixes, and notes. You can also create a project from here, and back everything up.
How to use it
Export a backup before switching phones โ your projects live on your device, not on a server.
Make the app speak your language โ literally.
The Homeowner/Pro toggle in the header adjusts how answers are written: homeowner mode uses plain language, Pro mode adds code references. The language picker supports 8 languages. Everything saves on your device, and the app installs to your home screen like a native app.
How to use it
Because data stays on your device, use Export in My Jobs whenever you want a backup you control.
Tap the feedback icon (speech bubble) in the bottom-right of any tab to send a report directly to the developer. Every report gets read and acted on.
