Building Pill Tracker with AI: A Focused App for Allergy Meds

At Horizon App Development, software should solve a real problem — clearly, privately, and without distractions. That mindset shaped our first iOS release: Pill Tracker — a lightweight app designed to help people (like me) stay consistent with their daily allergy medication.

This wasn’t just about building an app — it was about finally acting on an idea I’d carried for a while, and using AI tools to make it possible alongside a full-time job.

👤 Why I Built It

I have seasonal allergies, and I follow the 24-hour rule when taking my antihistamine. The problem is that I often forget when I last took it.

After a few too many "Did I take that already today?" moments, I realized this wasn't a calendar or health app problem—it was a consistency problem. One tap. One reminder. Every 24 hours.

I considered the idea for a few weeks, mentally sketching how to approach it. Then, on May 18th, I officially started building.

I've wanted to write and publish a "real" app for years, and this idea felt like the perfect entry point — narrow in scope, meaningful, and immediately applicable to me and others.

🧠 Staying Focused on One Thing

Before this app, I had experience building Discord bots, automation tools, and web-based projects — things that taught me the value of doing one Thing well.

That mindset carried into Pill Tracker. Instead of stuffing it with features, I built it around a single use case: reliably tracking your allergy pill once a day.

Every decision — from local storage to offline capability — came from that principle of clarity and minimalism.

🤖 How AI Changed Everything

One of the biggest enablers of this project was AI, specifically ChatGPT and v0.dev. With a demanding work schedule, I only had small windows of time to make progress, and AI tools made those hours count.

Here's how AI helped:

• Designing screens: v0.dev helped me prototype layouts and UI patterns fast
• Solving problems: ChatGPT was my go-to for debugging, architecture advice, and implementation help
• Staying productive: AI kept me moving — breaking down logic, answering questions, even generating component stubs

I wasn’t just writing faster — I was thinking clearer and avoiding burnout. It felt like working with a very senior dev who’s always available.

🧩 Core Features (So Far)

• 📴 No login, no internet, no tracking

Built using React Native + Expo, and available exclusively on iOS (for now).

🛣️ What's Ahead

Pill Tracker will keep evolving, but without losing its focus. Next up:

• More flexible reminder scheduling

All while keeping it private, simple, and offline-first.

💬 Final Thoughts

I didn't build this app in a vacuum — it came from a real need, a long-held goal to publish something meaningful, and the momentum of using the right tools at the right time.

Pill Tracker is a small app with a specific purpose — but it's also a milestone for me as a developer.

If you’re someone juggling work and projects, I can’t overstate how valuable tools like ChatGPT and v0.dev have become.
