Building mobile experiences that connect people with technology
We've spent the past eight years learning how businesses in Japan actually use mobile apps. Not the flashy stuff that wins awards, but the practical tools that help teams work faster and customers stay engaged. Based in Hiroshima, we work with companies who need apps that just work.
Let's Talk About Your Project
Started in 2017 with two developers and one client who took a chance on us. Here's what happened since then.
Everything from retail inventory systems to customer loyalty programs. Still maintaining 89 of them.
Most clients come back when they need something new. We take that as a good sign we're doing something right.
Combined downloads across apps we've built. Real people using tools we created every day.
There's no secret formula. Just careful attention to the stuff that actually matters when you're building something people depend on daily.
We spend time understanding what problem you're trying to solve, not just what features you think you need.
Real feedback from actual users before launch. Saves months of revision work later.
Swift for iOS, Kotlin for Android. Better performance, smoother experience, fewer headaches.
Apps need updates as operating systems change. We handle that so you don't have to think about it.
Connecting to your existing systems without breaking what already works.
Fast load times, smooth animations, minimal battery drain. The basics done well.
These clients let us share what we built together. Each project taught us something that made the next one better.
Operations Director, Retail Chain
Their old inventory system involved clipboards and spreadsheets. We built an app that lets staff check stock levels, place orders, and track deliveries from their phones. The warehouse team actually enjoys using it, which was not something I expected to hear.
Marketing Lead, Hospitality Group
We needed a loyalty program that didn't require staff training or complicated setup. RelayChainCom created something so simple that customers figured it out without instructions. Our repeat visit rate jumped within the first quarter, and we're now looking at expanding to our other locations.
We're in Hiroshima and work with businesses across Japan. Whether you have detailed specifications or just an idea you're exploring, let's have a conversation about what makes sense for your situation.
