We built Briefance to kill the 1–2 hour client scoping ritual

Hey PH 👋 Every freelance project starts in the same place. A client sends something like this: "Hey, I want a website. Something modern. Maybe like Apple but for our industry. Also can it do that thing where the menu sticks to the top? My cousin said we need SEO too. When can you start?" Then the ritual kicks in. You read it three times. Open a notes file. Try to figure out what they actually...

Briefance — Paste a messy client brief, get a structured proposal in seconds

"need a website, nothing fancy, $500, by Friday." That was an actual client brief I received. I spent 2 hours just figuring out what they actually needed before I could start working. After years of freelancing, I realized I was spending more time decoding chaotic client messages than doing the actual work. So I built Briefance. The problem: Clients send a wall of text vague scope, no timeline,...

The security gap in AI generated mobile apps

Shipped 3 Android apps last month using Cursor. Realized none of them had basic protections against: Debugging/reverse engineering Root detection Code injection AI writes functional code, but it doesn't think like a security engineer. Built a tool to bridge this gap upload .aab, get protection, no SDK integration needed. Would love feedback from fellow vibe coders.

When scanning is this easy (APK / AAB / Play URL), should mobile security start earlier?

Most teams delay security because scanning/building protection feels heavy. But if you can secure your app just by: Uploading an APK, Uploading an AAB, or Pasting your Google Play URL, …does that change the “I’ll secure it later” mindset? And if you want to ship a protected build immediately, Security Box just needs an AAB for final shielding. Honest question to devs/founders: Does easier...

Would you use a security tool that works with APK, AAB and Play Store links?

Most security tools lock you into a single upload format. But dev teams don’t always have the same build ready sometimes it’s an APK, sometimes an AAB, and sometimes the app is already live on Google Play. That’s why we updated AppShield to support: APK upload AAB upload Google Play Store URL scanning (And for Security Box specifically: AAB is still required for the final shielding build) No...

Which security risks worry you the most in mobile apps?

While building KOBIL AppShield, we studied dozens of real-world attacks. Some developers worry about reverse engineering, others about Frida/Magisk, and some about runtime manipulation. From your perspective as a builder: Debugging tools? Hooking frameworks? SSL pinning bypass? Root/JB devices? Automation attacks? Screen capture risks? App tampering? What keeps YOU awake at night as a mobile dev?

What’s the biggest mobile app security headache you’ve had?

We’re getting ready to launch KOBIL AppShield, and we want to hear from you. If you’ve ever shipped a mobile app, you probably ran into at least one of these: Integrating heavy SDKs Reverse engineering attempts Debugging/hooking tools bypassing your checks Rooted devices causing chaos Security reviews taking weeks Team lacking mobile security expertise What was the hardest or most annoying...
