Our own product: a marketplace app that connects customers with verified home service providers, with live GPS tracking, in-app chat, a wallet, subscriptions and a complete provider app.
Booking an electrician, plumber or cleaner usually means calling around, waiting without updates and hoping the right person turns up. Customers do not know who is coming or when, and good providers have no easy way to find steady work.
We wanted to solve the trust problem: show customers exactly who is coming and where they are right now, and give providers a fair, simple way to accept jobs and get paid.
RoundU is two apps on one platform. The customer app handles discovery, booking, tracking and payment. The provider app handles onboarding, document checks, accepting requests, navigation and earnings.
Live tracking was the core. Provider locations are streamed over sockets and stored with PostGIS, which lets the server find the nearest available providers and show customers a moving pin with an arrival estimate. Tracking works across multiple devices at once.
We chose a pay-after-service flow, so customers pay once the job is done and confirmed. A wallet and subscription plans reward regular customers.
