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.

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.

@appandflow + Huge bonus getting to collaborate with @janicduplessis and his team.

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!

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.

We regularly help companies navigate @expo SDK upgrades. Here’s a straightforward guide to the key steps we focus on. Bookmark it!
- Start with a full project audit
SDK version, dependencies, native modules, config plugins, build setup. Most risks are already hiding here.
- Read release notes deeply
Expo + React Native + platform changes. We map breaking changes before touching the code.
- Validate dependencies
Most issues come from 3rd-party libraries, not Expo itself. We check compatibility + maintenance status early.
- Upgrade strategically
Sometimes incrementally. Big jumps = bigger regressions.
- Review native configs
Gradle, iOS settings, prebuild behavior, config plugins. Auto-migration isn’t magic.
- Run real regression testing
Critical flows, navigation, performance, permissions, background tasks.
- Validate with real EAS builds
CI, environments, OTA readiness. Not just local builds.
Expo SDK upgrade isn’t just a version bump… it’s an opportunity to stabilize the foundation of your app.

Recent exploration work for one of our client's @expo app.
We incorporated a 3D model to spice up the onboarding flow and focused on morphing instead of navigating.

@beaverd We have similar stories in Canada, like a recent project that was originally estimated at $1 B (already outrageous) but ended up costing $6.7 B… and is an absolute disaster. Guess who was managing the project on the IT side?

This ad from @claudeai about ads coming to AI is absolute genius.

Ads are coming to AI. But not to Claude. Keep thinking.

We have the habit of changing our website every year at @appandflow, to reflect new trends and custom projects we've worked on throughout the year. 2025 was a year of 3D, AI and Crypto/Fintech for us!
Excited to what's coming this year!

10 years of App&Flow, and this one hit different. Huge thanks to all our customers. We couldn’t do this without your trust and support. New React Native architecture, Edge-to-Edge on Android, Liquid Glass, AI agents… 3D. Phew! Trends came full circle again: skeuomorphic → flat → skeuomorphic. Snip snap. What didn’t change? Great software still wins. AI doesn’t replace strong engineers, but it does make them sharper. In 2025, we rolled out Claude Code team-wide, tuned to our internal standards, and saw immediate gains in speed and quality. UX also took center stage. Working software isn’t enough anymore; it is the baseline. Performance, interaction design, and thoughtful native work are real competitive advantages, and we helped teams ship apps people actually remember. New website. New chapter. On to 2026…and the next 10 years

@adriankuleszo @designme Stunning! Love the bottom blurred out list!
