YEAR 2025Small Screen,
Big Moments.
Our tenth year was a big one! New RN architecture, Edge to Edge mandatory on Android, Liquid Glass, AI agents, 3D… Phew!What was once out of style is now trendy again. Skeuomorphic, to flat, and back to skeuomorphic. Snip snap, snip snap!One thing that remains timeless, however, is robust, well-crafted software. AI agents don’t replace great engineers, but they sure greatly enhance their efficiency. We started using Claude Code team-wide, with custom instructions to match our internal conventions and best practices, to great success.In 2025, we saw a strong emphasis on UX. Working software isn’t enough anymore; it is the baseline. Well-crafted apps, combining sound engineering and tasteful design engineering, are one of (if not the) best competitive advantages you can get. Whether it was performance improvements, complex interaction design, or custom native modules, we partnered with multiple teams this year to make their apps truly memorable.Now it is time to look towards 2026, to another 10 years, and, as always, adapt to whatever comes next.
ONWARDS!SIGNED: JAN 2026

About
HQ -> MTL,CANADA
UTC - 4
It all started with a blog in the early days of iOS development. We started publishing regular how-to articles about development on Apple devices. A few new clients later, App&Flow was officially founded in 2015 as a Montreal-based mobile app development agency. Later that year, Meta open-sourced React Native, and we were quickly excited by this new technology’s potential.Our early involvement in React Native was noticed by the talented engineers at Expo, and they gave us the opportunity to work together on their tools and modules. Our collaboration led to opportunities to work with startups coming out of Y Combinator, the best accelerator in the world.Since then, we’ve been busy building and helping companies of all sizes with their React Native engineering challenges. Lots has changed since, but our philosophy hasn’t. Give our best to build the best, over communicate, take ownership, and aim high.We deliver beautiful apps that work flawlessly, every time.
✌️
We're a close-knit team of developers, non-conformists, and old friends based in Montreal. Our goal is the same as when we first started: to build the best, most beautiful mobile products there are.
