Hi Bubble community, I’m a developer who specializes in pushing Bubble to its limits for high-performance mobile applications. I’ve noticed a common pitfall: many apps built on Bubble look fine on a small screen, but they feel slow, clunky, or just “not quite right” on a user’s phone. This is often because developers mistakenly treat the mobile view as just a resized webpage, ignoring the dedicated tools available in the new Mobile Editor. This isn’t a Bubble limitation it’s a choice of which elements to use.
The key to achieving a five star mobile UX is to abandon web centric elements. For instance, the standard Bubble Popup element is a block-level component designed for a desktop browser. On mobile, it covers the entire screen and halts all user flow, leading to a jarring, non-native experience. Instead, I always utilize the native Sheet element. The Sheet slides up from the bottom, mimicking the standard iOS and Android bottom sheet component used for quick settings and contextual actions. This allows the user to maintain context of the screen they were on, instantly elevating the app’s professionalism and adhering to crucial mobile design standards.
Another crucial area is performance. When displaying dynamic data, the traditional Repeating Group (RG) is often too slow on a mobile device, especially with large datasets or slower networks. A poorlyoptimized RG front-loads data, which can result in long loading screens and user abandonment. To fix this, I leverage the Mobile Editor’s specialized list components. For long, scrollable content like social feeds, the Vertical List is optimized for performance; it only renders items as they scroll into view (lazy loading), ensuring snappier load times and lower data consumption. Conversely, for small, fixed datasets like navigation items or category filters, the Short List is lightweight and ideal, loading everything at once for immediate UI responsiveness without the overhead of an RG.
Finally, a truly native app must interact with the device’s hardware, and I ensure my clients’ apps can do just that. Because the Bubble Mobile Editor is built on the React Native framework, we can access device-specific APIs through simple workflows. This is how you implement must-have features. For example, using Take Photo actions for instant KYC/ID verification, or using Send push notification actions to provide real-time alerts for appointments or transactions. These capabilities are non-negotiable for 90% of business applications, and my expertise ensures these features are integrated flawlessly.
If your project requires a truly polished mobile experience that can compete for 5-star reviews on the App Stores, I specialize in optimizing Bubble apps using these specific native elements and performance-driven structures. I ensure your app is built not just to function, but to feel native on both iOS and Android from day one, minimizing post-launch performance headaches.
