What’s Involved in Developing an App: A Beginner’s Guide

So, you have an idea for an app? That’s exciting! Whether it’s to streamline a business process, launch a startup, or offer a useful tool to the public, building an app can be a powerful way to bring your vision to life. But what exactly goes into developing one? This guide will walk you through the key phases of mobile app development to help you understand what to expect before jumping in.

1. Discovery & Planning

Every great app starts with a strong foundation. This phase is all about clarifying your idea:

  • What problem does your app solve?

  • Who are your users?

  • What features are absolutely essential?

This is also where market research and a basic app feasibility analysis come in. By the end of this phase, you should have a defined scope, a list of core features, and an understanding of how your app stands out.

2. Design & User Experience (UX)

Great apps are more than just functional—they’re intuitive and enjoyable to use. In this phase, you’ll:

  • Sketch wireframes of your app’s screens
  • Map out user flows
  • Create a clickable app prototype using tools like Figma

Mobile app UX design ensures your app makes sense from your users’ perspective and improves user retention.

This is where the technical magic happens. Developers begin coding your app based on the approved designs. Key decisions include:

  • Native vs cross-platform app development
  • Backend (server-side) and frontend (user interface)
  • Development frameworks (e.g., React Native, Flutter, Swift)
At Calibre Consulting, we typically recommend starting with an MVP (Minimum Viable Product) to launch faster and get early feedback.

4. Testing & Quality Assurance

Before launch, rigorous testing is vital. This includes:

  • Manual and automated testing
  • Usability testing with real users
  • Fixing bugs and refining features
Mobile app QA testing ensures that your app works as intended across different devices and user scenarios

5. Launch & Distribution

You’re ready to go live! At this stage, you’ll:

  • Create developer accounts on the App Store and Google Play
  • Prepare app store optimization (ASO) listings (descriptions, keywords, screenshots, etc.)
  • Submit your app for approval and go live

Launching isn’t the end—it’s the beginning of user acquisition and iteration.

6. Maintenance & Scaling

Apps aren’t set-it-and-forget-it. You’ll need:

  • Regular updates based on user feedback
  • Ongoing bug fixes and performance improvements
  • Planning for scaling your app if your user base grows
This is also where new features can be rolled out over time.

Costs and timelines can vary widely based on complexity. In general:

  • Simple MVP: 4–8 weeks
  • Medium complexity: 2–3 months
  • Complex platform: 6+ months
  • The average hourly rate for Canadians is from $80.00/hr to $170.00, depending on the project requirements.
App development costs should include design, development, testing, and post-launch support.

Conclusion: What’s Next? Developing an app is a journey, but with the right guidance, it doesn’t have to be overwhelming. Whether you’re just exploring the idea or ready to get started, we’re here to help.
