Today was a doozy, first time working extensively with @Shopify's skia , collision detection, and game dev with @expo @reactnative, as a mobile dev that's gotten used to the conventional Mobile app dev, this took me out of my comfort zone🤗. @VadimNotJustDev inspired this build.

1) add expo mcp
2) ask the agent to fix all of your TestFlight crashes
3) watch it magically work

@BoazWith Exactly, I faced this gap early this year and just knew we needed proper documentation done

I used my own tool to fix my landing page before launching it tomorrow.

WhyGoAI told me:
→ where visitors hesitated
→ why they didn't click the CTA
→ exact text to change (before → after)

Launching on Product Hunt tomorrow.

Apps don’t fail because of features.
They fail because of reliability.

Today, I fixed an app throwing “Network Error (status 0)”

→ Requests timing out
→ Weak network handling

Improved the request layer + made the app more resilient.

If your app feels unreliable, I can help.

@eniola_merem Hi

[FastheDeveloper @Fasthecr3ator]

Screenshots 🤝…

“I vibecoded my fintech app in 2 weeks.”

I can still MITM your users and read API traffic over WiFi.

“but we use HTTPS”; Your app trusts fake certs.

I’ll drop an article covering everything from screenshot blocking to SSL pinning, plus a GitHub repo with a demo app in RNExpo
