Why mobile

Why funded startups invest in mobile.

Your web app gets people started. Your mobile app keeps them coming back.

Web App
Desktop-first
  • Great for complex workflows
  • Opened when users remember to visit
  • Lives inside browser tabs
  • Mostly desktop-only
  • Email updates only
Recommended
Mobile App
Daily habit
  • Built for daily use
  • Lives on the home screen
  • Works online and offline
  • Push notifications for re-engagement
  • Faster actions on the go

Most startups don't replace their web products. They extend them with a mobile experience.

Faster Engagement

People open apps far more often than websites. Your product stays top of mind.

Better Retention

The products users rely on daily live on their phones — not in browser bookmarks.

Stronger Demos

A mobile app with a product video makes investor and customer conversations significantly easier.

Our process

How we work.

From first conversation to App Store in 45 days — here's exactly what happens.

Week 1 · Discovery

We understand your product.

We learn your core user flow, priorities, and what success looks like before any design work begins.

Week 1–2 · Design

We design the first screens.

Key mobile experiences in Figma, under your exact brand. Refined with your feedback before a single line of code is written.

Week 2–5 · Build

We build the app.

Approved designs become a fully working iOS and Android product. Weekly check-ins keep you updated at every step.

Week 5–6 · Video

We create the demo video.

A 60–90 second walkthrough with professional voiceover. Investor-ready and pitch-deck perfect.

We launch.

Day 45

Submitted to the App Store and Google Play. You receive the source code, the demo video, and full launch support.

No commitment required. We respond within 24 hours.

Why not build everything in-house?

Building internally

  • — Hiring takes time, especially when you need designers, developers, and video experience at the same time.
  • — Managing multiple freelancers often creates delays and handoff problems.
  • — Video production becomes its own separate project with its own timeline.
  • — Your team spends more time coordinating than shipping.
Fastest route

Working with Quartrex

  • Start immediately with one focused team instead of hiring multiple people.
  • Design, development, and demo video move together from day one.
  • You always know exactly who is building your product.
  • Simple goal: launch fast and investor-ready without the overhead.
Q

Built by a small, focused team.

We are a small team that works directly with every client — no handoffs, no project managers in between. When you reach out, you talk to the people actually designing and building your product. We work with a small number of startups at a time so each project gets full attention.
