I used Claude Code to build an iPhone app, Apple Watch app, and landing page… now it has 1,500+ users
I wanted to share a project I built with Claude Code and also explain the why behind it for anyone trying to build something similar.
The app is called LOC8. It started from a real problem I noticed in law enforcement. During foot pursuits, perimeter setups, large apartment complexes, alleys, backyards, or unfamiliar areas, it is easy to get turned around and need to quickly relay your exact location.
The idea was not to build another map app. The idea was to remove friction. Maps can give you a blue dot, but when you need the actual address, nearest cross street, GPS coordinates, heading, and accuracy fast, there are still extra steps. LOC8 puts that information on one screen for iPhone and Apple Watch.
Claude Code helped me build basically everything: the iPhone app, Apple Watch app, location logic, UI iterations, bug fixes, edge cases, and landing page. I used it heavily for React Native, watchOS, location handling, design cleanup, and keeping the product consistent.
The hardest part was not showing GPS data. The hard part was making it feel fast and useful under stress. I had to think through things like location accuracy, Apple Watch responsiveness, speed gating, driving versus walking, address refresh behavior, cached location data, and how much information is actually useful at a glance.
So far the app has grown to 1,500+ users, made a little over $1.5k in under 2 months, and has been around a 25% App Store product page conversion rate. Most growth has come from Reddit posts and manual outreach.
The biggest lesson for me is that Claude Code works best when you bring a real problem to it. It did not invent the use case. I understood the pain point first, then used Claude Code to help turn it into a working product.
For anyone one or two steps behind me, my advice would be: do not start with “what app can AI build for me?” Start with “what annoying problem do I understand better than most people?” Then use AI to help you move faster, test more ideas, and ship.
Would love feedback on the concept, the Apple Watch side, or how you would improve the product from here.
