From no-code prototype to iOS and Android in 8 weeks

Sentré connects clients with vetted professionals for in-person support. Its first version was a no-code prototype. We rebuilt it as a native app for iOS and Android, using AI-assisted development, and launched it on both app stores in two months.

The challenge

What needed to change

The no-code prototype proved the idea, but it could not support a secure, scalable launch.

A service that sends professionals to clients in person needs identity checks, background screening and safe payments from the very first release.

Our approach

How we got there

  1. 01

    A native app built to scale

    One React Native codebase for iPhone, iPad and Android, with every account, key and line of code owned by the client.

  2. 02

    Verified onboarding

    A 7-step flow for professionals: profile, Stripe Identity, Stripe Connect payouts, a Checkr background check and admin approval.

  3. 03

    Bookings built on trust

    Tiered bookings, escrow payments that split payouts automatically, fair rules for overtime and no-shows, and two-way ratings.

What we delivered

The solution

  • A native app for iOS, iPad and Android from one codebase.
  • Identity checks and background screening for every professional.
  • Escrow payments with automatic payouts through Stripe Connect.
  • Launched on the App Store and Google Play.
