Maybe your customers keep asking for an app, or a competitor has launched one. Before you spend money, it helps to see the whole journey. Here are the ten steps.
Step 1: Define the problem and the user
Write one sentence: “Our [type of customer] struggles with [problem], and our app helps by [benefit].” If you cannot, validate first — see how to validate an idea.
Step 2: Check whether you really need an app
A mobile-friendly website or PWA may be enough. An app makes sense for frequent use, notifications, device features or loyalty.
Step 3: List features and prioritise
Split features into must-have, nice-to-have and later. A first version needs only the must-haves. Examples of what small lists look like: our sample apps.
Step 4: Choose platforms and technology
Pick Android, iOS or both. A cross-platform framework builds both from one codebase — see Flutter vs React Native.
Step 5: Estimate budget and timeline
Use our app cost calculator and read how long app development takes. Keep contingency for changes.
Step 6: Design the experience
Start with simple sketches, then a clickable prototype. Test with a few real users before development begins. Good design is clear, quick and consistent.
Step 7: Choose your development partner
Compare scope, process, communication, ownership and support — not just price. Our checklist for choosing a company helps, as does understanding contract types.
Step 8: Build, test and refine
Development should happen in short cycles with regular demos. Test on real devices, check performance and security — see our mobile app security checklist.
Step 9: Launch on the stores
Prepare store listings: name, description, screenshots, privacy policy and support contact. Learn App Store Optimisation to help people find you.
Step 10: Promote, measure and improve
- Tell existing customers first; offer a reason to install.
- Track installs, active users, retention and key actions.
- Read reviews and fix problems fast.
- Release regular updates.
Common mistakes
- Building too many features at launch
- Skipping user testing
- No marketing plan
- Ignoring maintenance budget
- Choosing a developer purely on lowest price
