Mobile apps · iOS + Android

On their home screen. Not in your deck.

Put a real app in testers' hands through TestFlight and Play internal testing. We ship a working mobile MVP in 10 days at about 20% of what a traditional human team would cost. When users stick, the same code goes on to the App Store and Google Play.

What you get in 10 days

Installable.
Not clickable.

A real app on real phones, so you learn from how people actually use it, not from a Figma tour.

01

The loop you're testing

The few screens your idea depends on, working smoothly with real data, not placeholder text.

02

A backend that holds

Accounts, data and push notifications, so testers come back and you can see what they do.

03

In testers' hands

A TestFlight build for iPhone and a Play internal testing track for Android. Invite users on day 10.

Platforms

Native or cross-platform.
We pick for your users.

We choose the framework that fits your performance and maintenance needs, not the one that's easiest for us.

Swift · SwiftUI

iOS

Native iPhone and iPad apps, with TestFlight betas and App Store submission when you're ready.

Kotlin · Compose

Android

Native Kotlin and Jetpack Compose, with Play Console setup and internal testing tracks.

Flutter · Expo

Cross-Platform

One codebase shipping to both stores. Often the fastest way to test with iPhone and Android users at once.

JavaScript

React Native

Native rendering on both platforms, and code your React web team can share and maintain.

How it works

Idea to home screen.
Three steps.

  1. 01 · Minutes

    Pitch us the app

    Who opens it, and why they come back. Your ballpark timeline and cost arrives by email.

  2. 02 · 10 days

    Test builds on your phone

    Fresh builds as features land, plus a daily report on what changed and what's next.

  3. 03 · When it works

    Ship it to the stores

    We harden the same codebase for production and handle store submission and review.

Redplum Delivery OS™

Two platforms.
No dropped handoffs.

Mobile projects break between design and dev, between iOS and Android, and between QA and the store. Redplum Delivery OS™ puts an AI agent on each of those gaps.

  • Quality Agent checks every pull request for regressions, accessibility, device-size rendering and store guidelines.
  • Ops Agent reports daily on both platform streams, so you never chase an update.
  • Domain Skills cover push pipelines, biometric sign-in, offline-first sync and deep linking.

After the MVP

From TestFlight
to the store.

A test build that has to be rebuilt for launch is money spent twice. Your 10-day app grows into the store release on the same code.
