How I Built a Mobile App in a Week to Help Parents Fight Online Threats
The problem that wouldn't leave me alone
As a dad, I kept seeing the same headlines: kids getting targeted online, parents not knowing what apps their children are using, and no simple tool that helps families stay ahead of digital threats without turning into surveillance.
I wanted to build something that actually helps — not another parental control app that kids just work around, but a tool that educates parents and gives them actionable steps. That's how SafetyKit was born.
The stack behind SafetyKit.app
I built SafetyKit as a mobile-first web app using Next.js, Supabase for the backend, and Vercel for deployment. The AI layer uses Claude to analyze trending online threats and generate plain-English safety guides for parents.
The goal was speed: I wanted a working product in a week, not a prototype. Every tool was chosen because it let me move fast without sacrificing quality. Claude Code handled most of the heavy lifting — from API routes to the threat analysis pipeline.
Days 1-3: core features and the AI engine
The first three days were about getting the core loop working: parents sign up, answer a few questions about their kids' ages and devices, and SafetyKit generates a personalized safety report with specific risks and action items.
Claude Code built the entire threat analysis pipeline — it pulls from a curated database of known online risks, cross-references with the family's profile, and generates recommendations in language any parent can understand. No jargon, no fear-mongering. Just clear steps.

Push notifications and email alerts were critical — parents need to know when new threats emerge, not check an app every day. I used Resend for email and built a notification system that alerts families about relevant threats based on their kids' age groups.
The other challenge was making it feel approachable. Most security tools look intimidating. I wanted SafetyKit to feel like advice from a friend, not a cybersecurity report. Claude Code helped me iterate on the UI copy until it hit the right tone.
Day 7: shipped to safetykit.app
By the end of the week, SafetyKit was live at safetykit.app — a real product that real parents can use. Personalized safety reports, threat alerts, age-appropriate recommendations, and a clean mobile experience.
This project proved something I tell every business I advise: you don't need a team of 10 and six months to build something meaningful. With the right AI tools and a clear problem to solve, one person can ship a real product in a week. The bar has never been lower — the question is whether you have a problem worth solving.
