Building mobile apps is way more approachable these days, even if you're starting with a small budget or basic tools. Over the years, mobile app development has gradually slipped into a must-have category for businesses. From online stores to health services, companies are aggressively vying to capture the mobile app market, making their services available in the tiny devices we carry every day.
Generative AI and low-code/no-code platforms open the door for more people to jump into app development. In addition, cross-platform development with frameworks like Flutter and React Native means you can write code once and use it across different devices, while cloud systems keep costs down and apps flexible.
Still, it's not all easy. You need to keep up with fast-moving trends and the latest emerging technologies like AI in mobile apps, and hire mobile developers to build a mobile app successfully. With iOS and Android constantly changing, you are likely to come across different sets of challenges during development. Below, we list these common challenges in app development.
Challenges Faced by Mobile App Developers
Below are the challenges that you are likely to encounter when building a mobile app.
1. Fragmentation across platforms and devices
Making the app work across the different devices and platforms can drive you up the wall. Android is a bit flexible. But iOS has strict rules and guidelines. Then you have to find an environment that ships screens of all sizes and hardware for testing. This is not only expensive but also requires an in-depth testing strategy to resolve issues related to responsiveness.
It is a very common challenge you are likely to face when building apps for devices with different sizes. With native development, you will need to put more effort into it. There's a lifeline, though. Cross-platform frameworks like Flutter or React Native let you write your code once and roll it out everywhere, which saves a ton of hassle.
It keeps your app looking and feeling consistent. But cross-platform development has some limitations. Check out, we have already broken down the benefits and downsides of native and cross-platform approaches.
2. UX challenges
The most common UX challenges in mobile app development are;
- Platform and device fragmentation
- Crafting responsive and user-friendly interfaces
- Performance optimization
- Balancing functionality and aesthetics
- Keeping up with the latest UX developments
What is a common mistake many developers make? They add too much onto one screen and term it "feature-rich." It creates more confusion for users. As a result, you may lose a huge chunk of users if they have to spend time learning how to use the app. Balancing between aesthetics and features is tough. The best way to handle this challenge is to start with simple prototypes.
Let real people try them out, and keep tweaking based on their feedback. That's how you can solve the UX challenges.
*3. Choosing between development approaches *
The real challenge is choosing between native and cross-platform in the early stage. We should have put it first. You will find countless guides on native vs cross-platform that will make you feel lost. Native development is when you develop an app using OS-specific technologies. This is heavier on the wallet. You may need to use different teams for each platform. Alternatively, you can outsource mobile app development services.
On the other hand, with cross-platform, you can build an app with a single team. Tools like React Native and Flutter are very popular for this kind of development. It is not talked about enough, since cross-platform frameworks make it relatively easier. With cross-platform, you will not have that level of access to native components. While the native approach requires significant investment, the development cycle will be longer and costly. From development to testing, everything doubles with the native way.
Do you go native for each platform and maintain two codebases? Or do you choose cross-platform development but potentially sacrifice some native feel and performance? That's a decision with major long-term implications for both your budget and user satisfaction. We suggest that if you have a limited budget, go with cross-platform development, build an MVP, and test it out on both platforms.
4. Building user-friendly UI
When you invest in building a user interface, it is hard to say how it will translate to more revenue. Putting concrete numbers is tricky. You are constantly trying to make something that your users will like. Over and above that, getting everyone on the same page is another challenge you will encounter during UI development.
One team may want one thing, but your developers might not be able to pull that feature out; meanwhile, you're trying to keep everyone focused on what actually matters for the business. You can try the following methods to tone it down.
- Conduct A/B tests
- Use frameworks like the MoSCoW method
- Set up event tracking
5. Ignore hidden development charges
Most people start with a simple idea and don't realize how expensive building a quality app can be. The initial cost estimates could be a few thousand dollars. You might think you will need only $5000, but then discover you actually need around $10000, or two or three times the estimated cost. Hiring a mobile app development company from the region that is relatively economical compared to the US and Europe is not the only way to save yourself from a budget overrun.
Even after deployment, maintenance adds to the cost, including security and enhancements. Once it is built, ongoing costs require regular updates and investments. Some businesses plan to launch, but not in the next five years. In our recent article, we have already discussed app maintenance costs in 2025. You will end up spending more than planned.
It is often seen that, during development, everyone gets trapped in just one more feature trap. This is one of the most common factors that causes projects to go over budget. Here's how you can tackle this.
- Define must-have features upfront
- Create a realistic budget
- Prioritize features (MVP first)
- Choose the right development partner
- Avoid fixed-cost traps
- Use project management tools to monitor budget
- Plan for maintenance early
- Use cross-platform frameworks
6. Performance bottlenecks
A sub-optimal performance can have a negative impact on user retention, revenue, and brand reputation. In a Google research, it was found that if an app takes more than 3 seconds to load, more than 53% of users abandon it. A 1-second delay can result in a significant loss of potential users. The app store loves faster apps. Although it is an ever-growing process, you can make it easier.
Proactive monitoring is an excellent way to keep the app's performance optimal. With professional QA, you can check performance on mid-range phones. Plus, background activities are the top culprits that negatively impact an app's performance. Below are the areas where you can work to ensure the best performance.
- Test on mid-range and low-end devices
- Test on real devices
- Prioritize UI/UX budget
- Audit and optimize background process
- Monitor battery usage
- Reduce app size
- Build features on demand
7. Testing & QA challenges
Testing a mobile app properly requires an effective strategy and expertise to work with advanced mobile app testing tools. You are dealing with thousands of models. Android alone has more than 20k+ devices, and testing only on flagships is not the only solution. However, it is also not possible to run tests on hundreds or thousands of devices.
Cloud-based device farms like Firebase Test Lab or BrowserStack can make it easy to test on real devices and emulators. Automated testing can be the right approach, but the most important thing is to know how to use automated testing. It fails randomly, requiring developers to write deterministic tests. Tools with AI capabilities like Appium or Maestro can help automate major processes. Here's what you can do.
- Internal testers miss edge cases
- Roll out staged releases to 1% of real users first
- Add performance benchmarks to your tests
- Force testing on low/mid-range devices
- Use explicit waits, mock APIs, and avoid sleep() calls
8. App store competition
The app stores are crowded with millions of apps. After launching your app, the real hustle begins: becoming visible and earning top spots. Around 63% of apps are discovered through search, and if you're not in the top 10, you're likely invisible.
There are many algorithms and guidelines to consider. As we discussed, the app should be fast and follow standard UI practices to improve visibility in the app stores. Your icon, screenshots, and preview video determine whether users even click. A/B test them relentlessly. Show the real UI. Avoid using generic graphics to build trust.
Here are some tips to improve your app store visibility:
- Nail the first impression
- Use secondary keywords
- Time your feature drops
- Embed a "rate the app" prompt
- Offer offline value
- Add push notifications
- Focus on organic growth
9. Integration with third-party services
Integrating third-party services is not easy. You may encounter things working in the dev environment that break in production. This is a very common technical challenge in mobile app development.
Don't assume that any API will behave the same way in production as in development. Always mock external services when possible. Test things that can fail. Use Postman or Charles Proxy for that. Don't couple third-party services directly into your core logic. Create abstractions, e.g., a PaymentService interface.
If a provider changes (like Stripe) or even fails, you can swap out the service without having to refactor dozens of files. Monitoring should be mandatory. You need insight into latency, error rates, and the stability of your SDKs.
You can use something like Datadog or Sentry to help you quickly spot if things are not trending well. Always set alerts for your critical thresholds. For example, if your payment success rate goes below 95%, you should be notified immediately.
Always assume failure will happen. And build fallbacks - e.g., cached data is great, especially with non-critical APIs such as analytics. And you should document kill switches that allow you to remotely disable a malfunctioning SDK without needing to push an update.
The common problems are:
- It works in Dev, but not in production
- Sudden breaking changes
- Performance drag
- SDK conflicts, version clashes, and deprecated libraries
- Data privacy landmines
10. Post-launch maintenance
The real test for your app happens after launch. OS updates (like iOS 17 or Android 14) could break a feature overnight. Third-party SDKs can change on a dime. Users will find edge cases that your QA team missed. And it is less likely that competitors will stand still (while no one is watching). App maintenance isn't optional; it is the only way to become better.
Challenges you will face post-launch:
- OS or SDK updates will silently break your features
- Users will find bugs specific to their device
- One-star reviews hurt your growth
- Quick fixes create tech debt
- Competition becomes more appealing with inaction
Tips to Overcome Mobile App Development Obstacles
*1. Adopt agile development *
For agile development, Scrum or Kanban are popular tools to build apps in short cycles, so you can pivot when priorities shift, grab feedback early, and tackle surprises head‑on.
2. Leverage market research
Get to know your audience, their pain points, and what competitors are doing. Loop in real users throughout development so you're always on track.
*3. Embed security and UX *
Think about data protection and intuitive design from day one. Nailing these now saves you from rework later and keeps users happy and safe.
4. Plan scalable architectures
Design your backend and cloud setup to grow with your app. That way, you won't hit performance snags as your user base expands.
5. Test and iterate
Run tests at every step, fix bugs fast, and keep refining based on what you learn. This steady cycle ensures a smooth, reliable experience.
