@yuehan_john_ Yeah, that’s the tricky part. It feels like you’re moving faster at first, but you end up paying for it once the product gets bigger.

@appandflow the design debt argument is so real. we cut design system work early at silt to ship faster and it came back to bite us when engineers started making inconsistent decisions on their own. a shared system is actually faster in the medium term

UI, UX (and therefore design engineering) is something you should invest in as soon as you start planning your product. When deadlines get tight, it is often the first thing sacrificed.
When you have strong design systems in place, you’re assured of always having a solid baseline. It also makes it easier for engineers and designers to understand each other, raising the bar for quality release after release.

Expo just released Expo Agent!
We’re already seeing more and more product teams (in our portfolio) use tools like this to quickly prototype ideas, test flows, and validate features before committing engineering time. It’s a great way to move faster in the early stages of product development.
Curious to see how teams start integrating Expo Agent into their product workflows.

🙌 Today we're thrilled to introduce the beta of Expo Agent. At Expo our mission has always been the same: to make it as delightful as possible to build beautiful, powerful native apps. Expo Agent represents massive progress in our pursuit of that mission. Watch the video from @Baconbrix and get yourself on the waitlist right here: agent.expo.dev More details in the blog below ↓

Need a quick check on your app's quality? Here's a 20-minute triage checklist.
Three metrics to cover the essentials:
- Crash-free session rate (aim for 99.5%+)
- Cold start time (Android & iOS)
- Bundle size vs. industry benchmarks
The rule of thumb: if any metric is 2× the benchmark, it's worth a deeper investigation.
If all three pass, you're in good shape to move forward with confidence.
A simple routine to add before any release.

Solarin is proving that RN can handle any animation or interaction design you can imagine, reproducing some from the world's most beautiful apps in buttery smooth 60fps+.

Expo SDK 55 is here!!! Kudos to the @expo team for continuing to push the ecosystem forward!
Expo@expo
Expo SDK 55 is here😅 React Native 0.83. React 19.2. Legacy Architecture dropped. New Architecture is the default. ◆ 75% smaller update downloads with Hermes bytecode diffing ◆ Expo Router v7 🤯 ◆ Brownfield isolation via expo-brownfield ◆ AI tooling: MCP + agent skills for Claude Code ◆ Expo UI much improved for both Swift and Jetpack Compose There is so much more...it feels futile to try and isolate a few bullets...check out the full release notes and let us know what you think ↓

Building an SDK isn’t “just open-sourcing a wrapper.” It’s a commitment to other roadmaps, your clients products.
Common pain points we debug at App & Flow:
- Breaking API changes hidden behind “minor” bumps
- Inconsistent behaviors across Android & iOS
- Docs that explain what, not why, leaving users to reverse-engineer intent
- Dependency conflicts that break builds
- Versioning & release processes that create upgrade pain
- Edge cases only visible at scale
- Poor error handling that leaves users stranded
The fix? Treat your SDK like a product: use semantic versioning (major.minor.patch), write contract tests, and involve your community with RFCs.
For example, @stripe nails this, which is why onboarding feels frictionless.
Rule of thumb: If updating your SDK requires a Slack war room, it’s time for a process tune-up.

Proud to work alongside engineering teams that care about the details, that’s where strong mobile products are built.
Charles Vinette@Charlesvinette
Our best clients are product-driven companies with React Native and Expo at their core. They're led by strong engineering teams who value performance, stability, and long-term maintainability, not just shipping features fast. They come to us for deep expertise: improving performance, upgrading Expo SDKs, building complex libraries, solving challenges that go beyond standard development. They see mobile as a strategic product and want a team that understands RN at a senior, architectural level.

We've noticed a pattern with high-performing engineering teams:
They know when to build internally vs. when to bring in specialized help.
Common scenarios where external expertise makes sense:
- Performance issues that need immediate, focused attention
- SDK development that's outside your core product roadmap
- Quality improvements that can't wait for next quarter's planning
- Developer Experience improvements to increase team productivity
It's not about capability, it's about focus and priorities.
Your team could probably solve these problems. But should they, when it pulls them away from your core product goals?
We’ve built a consulting team at App&Flow that thrives in “special project” mode: deep dives, complex tech, hard deadlines.
If any of this sounds familiar, let's talk!

➕ Expo is additive.
If you have an existing bare React Native app and you want to modernize it there are clear, approachable steps you can take to begin adding Expo to your app.
We outlined them in this blog post (which was inspired by a conversation with a team hoping to add Expo a massive React Native app): expo.dev/blog/how-to-in…

Had a few people ask about our website redesign, so here goes!
We are big fans of simplicity, a "no-fluff" kind of team, so a one-pager was a no-brainer. But we love giving extra attention to details! So our goal was simple: how can we pack the most punch in a one-pager? In 2025 we became big fans of creating wow moments with 3D models, so using one in our hero was only natural.
We worked with our long-time collaborator Nicolas Solerieu on the model, highlighting the heart of what and who we are: a React Native engineering team from Montreal.
Tried to sprinkle as many little details and interactive elements as possible without losing usability or overdoing it.
