Should I Build an App for My Business?

Every week, we speak to founders who've already decided they need an app. Most of them don't. Here's how to figure out whether you actually do — before spending £20,000 to £100,000 finding out the hard way.

The Question Most Founders Skip

The default assumption in 2026 is that every business needs an app. Investors expect one. Competitors have one. Your mum thinks you should build one. But the question isn't "should I build an app?" — it's "what problem am I solving, and is an app the best way to solve it?"

At GoMVP, we've consulted on dozens of product ideas. Roughly 40% of the founders who come to us convinced they need an app leave with a better, cheaper solution. Not because we talked them out of it, but because we helped them think clearly about the problem before jumping to the solution.

When You Probably Don't Need an App

Here are the most common scenarios where building an app is the wrong move:

• Your "app" is really a website. If users visit once a week or less, don't need offline access, and aren't performing complex tasks, a responsive website does the job at 10% of the cost. A Progressive Web App (PWA) can bridge the gap if you need push notifications.
• You haven't validated the core value proposition. If you're not yet sure people will pay for what you're building, an app is the most expensive way to find out. Start with a landing page, a waitlist, or a manual service. Validate demand before writing code.
• An off-the-shelf tool already exists. Before building a custom booking system, check Calendly. Before building a customer portal, check Notion or Airtable. The best MVP is often no code at all — just the right combination of existing tools stitched together.
• You're building for a tiny audience. If your total addressable market is 200 people, the unit economics of a £50,000 app don't work. Consider a spreadsheet, a WhatsApp group, or a simple web form.

When You Probably Do Need an App

An app makes sense when:

• Users need real-time interaction. Messaging, live tracking, collaboration tools — these require persistent connections that apps handle well.
• Device hardware is essential. Camera, GPS, Bluetooth, NFC, biometrics. If the core experience depends on hardware access, you need a native or hybrid app.
• Offline functionality matters. Field workers, delivery drivers, remote inspectors — if your users can't rely on internet access, an app with offline sync is necessary.
• High-frequency, habitual use. If users interact with your product multiple times daily, the convenience of a home screen icon and native performance matters.
• You've already validated demand. You have paying customers, a waitlist, or strong evidence that people want what you're building. Now it's time to build it properly.

The Decision Framework

Ask yourself these five questions:

1. Have I validated that people will pay for this? If no, stop here. Validate first.
2. Can I deliver the core value with existing tools? If yes, do that first. Build custom technology only when off-the-shelf breaks down.
3. Does the experience require device hardware or offline access? If no, a web app is probably sufficient.
4. Will users interact with this daily? If no, a responsive website or PWA is likely better.
5. Do I have the budget for ongoing maintenance? Apps aren't one-off purchases. Budget 15-20% of build cost annually for updates, hosting, and bug fixes.

What Should You Build Instead?

If the framework tells you an app isn't the right move yet, here are better starting points:

• A responsive website with clear CTAs. Cost: £500-£5,000. Timeline: 1-4 weeks.
• A no-code prototype. Tools like Bubble, Glide, or Softr let you build functional products without code. Cost: £0-£2,000. Timeline: 1-2 weeks.
• A concierge MVP. Deliver the service manually before automating it. Cost: Your time. Timeline: Immediate.
• An AI-built prototype. Use tools like Claude, Cursor, and v0 to build a working prototype in days, not months. This is what our AI Guidance & Training sessions teach you to do.

The Bottom Line

Building an app is a significant investment. The founders who succeed are the ones who validate their idea cheaply before committing to expensive development. The founders who fail are the ones who build first and validate later.
