Let’s be honest: we’ve all used business apps that felt more like a maze than a tool. You open it up and instantly wonder—Who designed this? Why is everything buried under five layers of menus? Why is the button I need microscopic?
As developers, we’re often laser-focused on backend logic, data structures, or integration workflows. But all that brilliance can get completely overshadowed by one thing: a bad user experience.
I’ve seen it happen. I’ve built apps that worked perfectly… but users hated using them. And that’s a problem—because in business apps, usability isn’t just a “nice to have.” It’s mission-critical. If people can’t find what they need or complete their tasks quickly, productivity tanks.
So, here are five UI/UX mistakes I see all the time in business apps—and how you can dodge them. Bonus: I’ll show you how Bellini, our app builder at Lonti, makes it way easier to avoid these pitfalls.
Ever seen a dashboard that looks like a spreadsheet collided with a command center? Yeah, me too.
The mistake: Cramming every widget, every button, every option onto a single screen because “the user might need it.”
The fix: Embrace hierarchy. Group related actions. Use progressive disclosure (i.e., only show advanced options when needed). Less is more—especially when clarity drives speed.
If clicking around your app feels like jumping between completely different apps, you’ve got a navigation problem.
The mistake: Pages or sections that don’t follow a consistent structure—menus in different places, actions that move around, unexpected back behavior.
The fix: Stick to predictable patterns. Keep navigation consistent across the app. Use breadcrumbs, headers, or tabs to give users a sense of where they are and where they can go next.
Yes, it’s a business app. But that doesn’t mean users only access it from their laptops. Tablets, phones, even embedded devices—it all counts.
The mistake: Designing purely for desktop and ignoring mobile responsiveness. Result? Broken buttons, unreadable text, and frustrated users.
The fix: Design mobile-first or at least mobile-aware. Test your UI across different breakpoints. Prioritize touch-friendly components and adaptive layouts.
Ever clicked a button and wondered, Did that actually do anything?
The mistake: Not giving users immediate feedback on their actions—submitting forms, saving data, triggering a workflow.
The fix: Always acknowledge the action. Use loaders, confirmation messages, toasts, or visual state changes. Uncertainty is the enemy of confidence.
Business apps often get a pass on accessibility—but they shouldn’t.
The mistake: Designing only for mouse users, ignoring screen readers, or skipping keyboard navigation altogether.
The fix: Respect accessibility standards. Use semantic elements, ARIA labels, and keyboard-friendly controls. Remember, inclusive design is just good design.
You don’t need to be a UI/UX designer to build a great experience. You just need to care about it—and use the right tools.
That’s why we built Bellini the way we did. It’s not just a low-code app builder. It’s a developer-first, API-powered tool that helps you build apps people actually enjoy using. Clean UIs. Clear flows. No limits.
If you’re tired of hearing users say “this app sucks”—start fixing the UX. You’ll be surprised how quickly everything else improves too.
