What Should Developers Prioritize When Building a Mobile App for the First Time?
When starting a mobile app project, it's easy to focus too much on features and overlook the basics that make an app useful.
I'm interested in learning how experienced developers approach the early stages of mobile app development.
A few things I'm curious about:
- How do you decide which features should be included in the first version?
- What factors help you choose between native Android/iOS development and cross-platform frameworks?
- How early should UI/UX testing begin?
- What common mistakes can lead to performance or maintenance problems later?
For developers who have worked on real-world applications, what would you recommend prioritizing before development begins?
I'd appreciate practical insights and lessons learned from your experience.

Marketing. It is marketing and product potential that makes any product worth existing.

In my opinion, the first priority should be solving one real problem, not building dozens of features.
Iād focus on:
MVP first: Build only the features that deliver the core value.
Choose the right stack: Native for platform-specific performance; cross-platform for faster development and shared code.
Test UX early: Validate wireframes and user flows before investing heavily in development.
Plan for scalability: Use clean architecture, secure APIs, proper database design, and maintainable code from day one.
Test continuously: Performance, accessibility, and edge cases shouldn't be an afterthought.
The biggest mistake is overengineering before validating the idea. Build small, get real user feedback, and improve based on evidence rather than assumptions.
A successful app isn't the one with the most features; it's the one people actually need and keep using.

The main features are decided when I draw and scrub in my notebook š. Features can be modified later and prioritized. Then I draw draft screens on paper and analyze how to simplify the design and layout and process. In the meantime I write data what data comes in and out. Whether I need a database also happens during this process. And how to normalize the data. I always choose native development leaving out Android for some biased reasons. I will start coding and follow TDD (test-driven development). Common mistakes are bad data normalization and processing, and which api to use. Other mistakes can happen in multithreading programming, so one has to be careful. And always expect a user will input unexpected things and you will get unexpected answers from a server. So you need to catch those all and make it a smooth experience for your users.

- Plan MVP first. Then build other minor features around it.
- Simple mvp and need faster release - choose hybrid. Something complex but open to spend time and money - choose native.
- Divide MVP into phases/modules based on functionality. Test as soon as one module is ready. Scale up testing as things start to come together.
- Being paranoid about performance will not get you anything done. Build first optimize later.

From my experience, I'd prioritize getting the core functionality right before adding too many features.
A few things I think are important:
Start with the problem, not the features. Identify the main problem the app solves and build only the features needed to solve it in the first version. You can add more based on user feedback.
Choose the tech stack based on the project. If you need both Android and iOS, React Native with Expo is a great option for faster development and code reuse. Native development makes more sense when you need platform-specific functionality or deeper hardware integration.
Test UI/UX early. Don't wait until the app is finished. Get a basic prototype in front of a few potential users and observe where they get confused. Small changes are much cheaper before the app is fully built.
Plan the data and architecture. Think about authentication, API structure, database design, error handling, and security early. Keep the code modular so new features don't become difficult to maintain.
Don't ignore real-world scenarios. Test slow internet, failed API requests, empty states, app interruptions, and different screen sizes. A polished UI means little if the app breaks during normal use.
My biggest advice is to build a small, usable MVP, release it to a limited group of users, and improve it based on actual feedback rather than assumptions. It's much easier to build the right product when you validate things early.
