With over a decade of experience and a stint at Apple and Google under my belt, I understand the critical importance of optimizing and revamping existing codebases to extend their life-cycle efficiently. My previous projects in particular, revamping Flutter apps, align perfectly with your requirements. My approach includes an initial deep dive into your existing code structure, identifying its strengths and weaknesses to craft a well-informed upgrade plan. I will modernize your app to match current designs, resolve any performance issues or memory leaks that may have arisen, improve features and source code unit testing with up-to-date REST API integrations using best practices in Flutter. My transparent client-centric development process ensures you'll be consistently informed with concise explanations of significant code changes and regular updates on progress through the app. One key differentiator separates pros from amateurs - effective communication.

Hi, I can help refresh and upgrade your existing Flutter app for both Android and iOS with clean UI improvements, feature updates, API compatibility fixes, and performance tuning. I have strong experience taking live Flutter apps from older/legacy builds to stable refreshed releases, including UI polish, crash fixes, REST API updates, memory/performance debugging, regression testing, Firebase integrations, and App Store/Play Store release support. My approach: - Review existing codebase and identify crashes/performance issues - Refresh key UI screens with modern Flutter best practices - Update required features and REST API integrations - Test all major flows on Android and iOS - Provide frequent Git commits with clear notes on what changed and why Estimated timeline: 2–4 weeks depending on the number of modules and UI changes. Cost: Can be shared after reviewing the repo/scope, or we can work hourly/milestone-wise. I can share relevant Flutter app links and builds I’ve worked on, and once I get repo + staging API access, I can start with a technical review and milestone plan.

Hi, I’m Vandini, an individual freelancer with experience in Flutter app updates, UI/UX improvements, REST API integration, debugging, and Android/iOS build testing. I can help refresh your existing live Flutter application by improving key screens, fixing crashes or slow performance issues, updating REST API integrations, and making sure the app remains stable on both Android and iOS after changes. My approach will be to first review the existing code, identify UI and performance issues, check crash points, update required modules, test API compatibility, and then run regression testing before final handover. I’ll keep the Dart code clean, structured, and easy to maintain, with regular Git commits so you can track progress clearly. The current bid is based on the shared details. Final effort, timeline, and cost may vary depending on the full module list, current code quality, number of UI screens, API changes, and debugging complexity. Estimated timeline: 5–10 days after repo access and final scope review. I can share a proper milestone-wise plan after checking the app flow and exact enhancement list. Best regards, Vandini

@ashutoshv8

Hi, This is exactly the kind of project I enjoy—taking a live Flutter app and refining it into a fast, modern, and stable product. I’ve worked on updating existing apps where the focus was UI refresh, fixing hidden performance issues, and aligning features with backend changes. I understand that this isn’t just about adding features—it’s about improving the overall experience without breaking what already works. Here’s how I’d approach your app: • Refresh UI/UX with a clean, modern look while keeping it intuitive • Identify and fix crashes, memory leaks, and performance bottlenecks • Update and stabilize REST API integrations with your backend • Improve app responsiveness and optimize heavy screens • Run full regression testing on both Android and iOS I follow clean Flutter architecture (modular structure, proper state management) and maintain clear Git commits so progress is always visible. I also make sure to document key fixes and decisions so everything remains maintainable. You can expect consistent communication and quick updates throughout the process. Estimated approach: Week 1: Audit + bug fixes Week 2: UI/UX improvements Week 3: Feature updates + API alignment Week 4: Testing, optimization, and final polish I’d be happy to review your current build and suggest a precise plan with timeline and cost. Best regards, Ashutosh

I'll handle it, don't worry. When an app loses its edge users don’t just notice, they move on. Your need for a modern and seamless experience that feels fast again isn’t just cosmetic it’s mission-critical. My approach involves refreshing key screens with up-to-date UI/UX that genuinely improves engagement by hunting down sneaky crashes and slowdowns and updating REST API links to keep backend harmony. I'll deliver clean documented Dart code with rigorous Git tracking which will ensure a user-centric and integrated upgrade that’s smooth on both platforms. Although I am new to the Freelancer platform, I bring a wealth of real-world experience and a proven track record of successfully delivering projects beyond this platform.

Let's connect and explore how we can bring your vision to life. Regards Ahead Solution P.S If your not happy with our work, which we doubt, you don't pay.

@macymind

Hi I have quick question before we start are you seeing more issues around performance/crashes, or is the bigger concern making the app feel modern again? From your description, it sounds like the app already has a solid base and mostly needs the right cleanup and refinement to get it back to a smooth, reliable state. I’ve worked on Flutter apps in a similar stage, where the focus was: --Fixing lag, crashes, and API inconsistencies --Refreshing older screens without disrupting existing flows --Improving stability before pushing new releases I’m comfortable stepping into existing codebases and figuring out quickly what should be fixed, improved, or left untouched to avoid unnecessary rework. Once I review the current app, I can give you a clear breakdown of: --What’s causing the biggest issues --What can be improved safely --The fastest path to a polished release Regards, Manish P.
