No add-ons, no surprise fees. Every feature below is included and production-ready.
Snap photos on site. Photos auto-compressed. Takes 90 seconds.
Pre-built templates for new builds, kitchen remodels, bath remodels, additions, and general renovations. Toggle and customize per project.
Tap the mic and talk. Speech-to-text dictation for notes — hands-free on the jobsite.
Homeowners get a single link — no account, no password. Bookmark and done.
Homeowner journal auto-refreshes the instant a builder posts. No page reload needed — powered by Supabase websockets.
"Owner last viewed 2 hours ago." Builders know exactly when homeowners check in.
Auto-logged timeline of every project event — check-ins, phase changes, document uploads. Zero manual work.
Search across all check-in notes instantly. Postgres-powered tsvector indexing under the hood.
Database webhooks automatically email homeowners on every new check-in and phase milestone. Builder does nothing.
Summary or full report, date-range filtering. Professional PDF downloads with builder branding.
Weather conditions captured automatically from GPS. One less thing to type.
Upload invoices, permits, plans. Snap a photo or upload a PDF. Owner-visible toggle.
Track material choices with photos, status, and links. Homeowners can leave feedback on each selection.
Document scope changes with cost impact. Homeowners can acknowledge or decline with one tap — no account needed. For communication purposes; formal contracts handled separately.
End-of-project issue tracking with photos and resolution status.
Run concurrent phases (roofing + rough-in). Auto-calculates primary phase. Quick-pick buttons on check-in form.
Architectural drawings get a dedicated visual section in the journal. Large image previews for homeowners to reference anytime.
Homeowners leave notes on material choices directly in the journal. Builders see feedback inline on their dashboard.
Old magic links auto-redirect to current. Preserves the 'bookmark it once' promise. Hard-revoke option available.
Every check-in timestamped with photos and weather. Evidence if there's ever a dispute.
System-aware dark mode. Looks great on any device, day or night.
Add to home screen for native app feel. Works on any phone, no app store.
Documents, change orders, and punch lists can be locked behind a PIN with server-side verification — protected data is never in the DOM until the correct code is entered. The story stays open; the money stays gated.
Per-check-in save button. On mobile, uses the native share sheet to save directly to Photos. On desktop, downloads as a ZIP. Works via server-side proxy — no CORS issues.
Automatic email to homeowners when the build reaches a new phase.
No signal on the jobsite? Open a project once with signal and you're set — check-ins save locally and sync automatically when you're back online. Built for rural Maine.
Guided onboarding walks new builders through setup. Dismissable anytime — skip or complete at your own pace.
Pre-populated demo project with fake data. Explore every feature without touching real projects. Perfect for evaluating the product.
Multiple builder-only notes per project. Jot reminders, sub contact info, or budget notes — never shown to homeowners.
Automated daily email to builders who haven't posted in 5+ days. Keeps the communication habit alive.
Public gallery page of completed projects. Add the link to proposals and bids — proof of process, not just promises.
Search builders, manage plans, toggle sponsorships, set trials. Everything an operator needs to run the business.
FAQ page and support contact surfaced inside the dashboard. Builders get answers without leaving the app.
Full documentation for operators: env vars, deployment, database, common tasks, transfer checklist. Ready for handoff.
With 47 features already built, the roadmap is focused on growth. Here is what comes next.
Invite foremen and subs to check in on projects. Role-based permissions.
Fully branded experience. Your logo, your colors, your domain. Resell to other builders.
Auto-generate descriptive captions for jobsite photos. Save builders even more time on check-ins.
Subscription billing is already wired up. Free, Pro ($79/mo), and Growth ($149/mo) tiers with annual discounts.
New builds AND remodels. Residential contractors are underserved by existing tools. The big platforms are built for commercial GCs. Plinth fills the gap.
