Mobile app development for service businesses

Plainbuilt builds mobile apps for service businesses: field-technician apps, customer booking apps, fleet and dispatch apps, estimating apps, and an owner's assistant in a pocket, in React Native on Supabase, Node, and Twilio, wired into the systems you already run. An engineering practice since 2014 with 200+ shipped projects; we build the systems our AI runs on.

It puts the job in the hands of the person doing it. A field-technician app with the job card, the photos, and the checklist. A customer booking app that lets a homeowner book without a call. A fleet and dispatch app with the board on the driver's phone. An estimating app that turns photos into a quote. A crew scheduling app. Patient intake apps, real estate showing apps, companion apps for hardware, and marketplace and community apps: the ten categories in the portfolio are the shapes we have shipped.

Every app is built in the stack we ship in: React Native for the app, Supabase and Postgres for the data, Node for the services behind it, and Twilio for texts and calls. It is wired into the system your operation already runs on, ServiceTitan or Jobber for a contractor, so the app is not another place to type things in.

A build runs discovery, spec, build, ship, support. The working session opens discovery; the spec is the build plan; the app ships into the live operation; and we keep it running after that. Every deployment carries a written ROI commitment, and a custom build is no exception.
