Service

Mobile apps.

Tap, swipe, and interact with your idea on a real device. We engineer cross-platform mobile prototypes that feel native, built rapidly for market validation.

The mobile advantage

01

Cross-Platform by Default

We build using frameworks like Flutter or React Native. That means your prototype runs on both iOS and Android from day one, doubling your testing pool.
02

Native Feel

Animations, gestures, and haptic feedback. Your prototype won't feel like a web page in a shell; it will feel like an app.
03

On-Device Testing

We deploy directly to your phone via TestFlight or Expo. TestFlight distribution runs through your own Apple Developer account, so that needs to exist before the first build. You and your investors can then tap through the experience as a user would.
04

Hardware Integration

Need the camera, GPS, or accelerometer for your core feature? Our prototypes can tap into native device hardware to prove out complex functionalities.
VALIDATION VELOCITY

Put your app in their hands.

Clickable Figma mockups are great for design reviews, but they fail to capture the true friction of a mobile experience. You can't test load times, complex gestures, or real-world data entry with a mockup.

Our rapid mobile prototyping service delivers an actual, installable application. We focus on the "hero flow" — the one or two key interactions that make your app unique — and build those properly.

When you sit across from an investor or a potential user, you don't show them a presentation. You hand them your phone and let them experience the product. That tangible interaction is what separates a demo people watch from one they use.

WHAT YOU GET
  • ◆Installable app on iOS and Android
  • ◆Smooth, native-feeling animations
  • ◆API integration for core "hero flow" data
  • ◆Premium mobile UI/UX design
  • ◆Clean, scalable React Native / Flutter code
Questions

Questions about Mobile Application Prototypes.

Will the prototype run on both iOS and Android?

Yes. We build on cross-platform frameworks (Flutter or React Native), so a single build runs on both iOS and Android from day one — doubling your testing pool without doubling the work.

How is it different from a Figma prototype?

A Figma prototype is a clickable image; ours is an installable application. It captures real load times, gestures, haptics and data entry — the friction that determines whether people actually use your app.

Can it use device hardware like the camera or GPS?

Yes. When your core feature depends on the camera, GPS or accelerometer, we tap directly into native device hardware to prove the functionality works, not just that it looks plausible.

How do I get the app onto my phone for demos?

We deploy directly to your device via TestFlight or Expo, so you and your investors can tap through the real experience during any pitch or user session. TestFlight distribution runs under your own Apple Developer account — worth setting up early, because enrolment is not instant. A TestFlight build is a test build, not an App Store release.
