Your mobile app should feel fast. We make that happen.
We work with development teams in Japan to find the bottlenecks slowing down their mobile apps. No buzzwords, no magic promises. Just practical performance improvements that users notice.
Talk about your app
How we approach performance problems
Most apps get slower over time. Features pile up, frameworks evolve, and suddenly your users are complaining. Here's how we help you dig out.
Measure what matters
We start by profiling your app under real conditions. Screen transitions, API calls, memory usage. The stuff that actually affects user experience.
Find the worst offenders
Not every slow function deserves attention. We identify the patterns causing the most lag and prioritize based on impact.
Fix it properly
Sometimes it's lazy loading. Sometimes it's a database query. We implement solutions that fit your codebase and don't create new problems.
Keep it fast
We set up monitoring so you can catch regressions early. Performance is not a one-time project. It's a practice.
The problems we see most often
After working with dozens of teams across Tokyo, Osaka, and other cities, we've noticed patterns. Apps built quickly during launch phases often carry technical choices that made sense at the time but become bottlenecks later.
The worst performance issues rarely come from obviously bad code. They come from reasonable decisions made under pressure that compound over months. A slightly heavy library here, an unoptimized query there. Then someone adds offline sync and suddenly everything grinds.
- Uncontrolled main thread work blocking UI updates
- Memory leaks from retained closures and observers
- Inefficient image caching strategies eating bandwidth
- Background tasks competing with user interactions
- Database schemas that don't scale past prototype data


What it costs to work with us
We keep pricing straightforward. You pay for the time we spend on your app. Most projects fall into one of these ranges depending on complexity.

"Our app was basically unusable on older devices. NodeBridgeFlow spent three weeks with our team identifying problems we didn't even know existed. Load times dropped by 60% and crash reports fell off a cliff."
"We thought our performance issues were just 'how React Native works.' Turns out we had some seriously inefficient patterns. They showed us exactly what needed fixing and why. App feels completely different now."
