A mobile app that worked great just a year ago can look outdated and frustrate users today. The world of technology changes at lightning speed, and expectations for interfaces grow month by month. When should you redesign an app and how do you recognize that the right moment for changes has arrived? In this article, we show the most important warning signs that say redesign has stopped being an option and become a necessity for business growth!
Dropping ratings and negative reviews
Ratings in the App Store and Google Play are the first indicator of app problems. Rating droping below 4 stars or a series of negative comments – these are clear warning signs. The most common problems regarding a lack of updates include: navigation difficulties, unclear interface, or problems finding basic features.
It’s worth regularly checking the content of reviews because users directly say what frustrates them. Repeated complaints about the same elements are proof that the problem is serious and requires fixing. Ignoring feedback leads to losing users who find better solutions from competitors.
Users don’t return to the app
If more and more people install the app, use it once, and never come back, it’s a sign that first impressions are disappointing. The problem may lie in complicated onboarding, unclear app value, or a difficult-to-use interface. Data shows exactly how many people abandon the app after the first day.
Signs that users are leaving:
- People spend less and less time in the app
- The number of people who delete the app within the first few days is growing
- The number of active users is dropping despite growth in installations
- Usage of key app features is declining
- The number of abandoned carts or incomplete actions is increasing
User behavior analysis can show exactly where they lose interest and give up. These places require redesign as a priority.
Outdated look and old standards
Trends in mobile app design change every few years. An app created five years ago may look outdated today. Flat design, minimalism, dark mode, or rounded buttons are standards that users expect today. An outdated interface affects the perception of the brand as a modern company.
Old standards aren’t just about appearance, but primarily about usability. Solutions that were acceptable in the past, like small buttons, hidden menus, or long forms, irritate users today. The app should be intuitive for new people without needing to read instructions. We know from practice that modern design significantly improves first impressions and encourages continued use.

The app looks bad on new phones
Every year, new smartphone models appear with different screen sizes and proportions. An app designed a few years ago may look bad on the latest devices with elongated screens or foldable smartphones. Black bars on the sides, cut-off interface elements, or poorly fitted graphics are signs of outdated design.
Problems with new devices:
- The interface doesn’t fill the entire screen on the latest phone models
- Buttons and elements are poorly positioned on foldable smartphones
- Graphics look blurry on high-resolution screens
- The app conflicts with new iOS and Android system gestures
- Text is too small or too large on screens with unusual proportions
New versions of iOS and Android systems also introduce changes in operation, like gestures instead of buttons or new on-screen elements. Apps that don’t account for these changes can cause navigation problems and frustrate users. Redesigning allows you to adapt the app to current mobile platform requirements.
More and more support questions
If users increasingly contact technical support asking about the same things, it’s a sign that the interface isn’t clear enough. Repeated questions like “where can I find…” or “how can I…” show problems with the app’s layout. Good design should be understandable without reading instructions.
Support ticket analysis is a valuable source of information about which elements require redesign. Reducing the number of questions about basic features after redesign is clear proof of success. Most usability problems stem from an unclear interface, not a lack of features.
The company is growing and strategy is changing
An app designed for a startup with a few hundred users may not work when the company grows to tens of thousands of customers. Changing the business model, expanding the product offering, or entering new markets often require thorough redesign of the layout and interface.
Adding more features to an old interface stops working at some point. It’s better to redesign the whole thing, planning development for the coming years. Strategic changes should consider not only current but also future business needs and user expectations.
Competition is better visually and technically
Regularly checking competitor apps shows what the industry standard looks like. If competitors have introduced new features, better interfaces, or more efficient processes, and the app falls behind, users will start migrating to other solutions. Competitive advantage is a signal that the market has moved forward.
It’s not about copying competitors’ solutions, but about being aware of current standards in the industry. Redesign is a chance to regain advantage and stand out from other apps. Sometimes a few key changes are enough to significantly improve market position.
Is it worth investing in redesign?
The decision to redesign should be based on data, not just intuition. If you see drops in app usage, a growing number of negative reviews, and rising support costs, redesign stops being an expense and becomes an investment that saves the business. At The Code Brothers, we know that redesign doesn’t have to mean changing the entire app – sometimes it’s enough to modify the most important user paths and refresh the look.
