RidgeLine HVAC
Field mobile app | Design & build | React Native, Postgres
Starting at $89.99 for scoped mobile module; full build quoted separately
Checklist app for HVAC techs: photos, parts used, customer sign-off, and invoice data synced before they leave the driveway.
The problem
Paper forms came back incomplete. Office staff retyped everything. Invoices lagged days behind the job.
What I built
Offline-friendly mobile forms that sync when they hit LTE, with admin view for dispatch and billing.
Results
- Same-day invoicing on most jobs
- Office cut re-entry time by ~8 hrs/week
- Works in basements with bad signal
