Building a location-based app as a solo developer

MessageDrop is not built by a large company or a big product team.

It is an independent project that I develop step by step as a solo developer — which means that the work behind it is often much broader than what users see on the surface.

The visible parts are things like:

🗺️ Maps and location-based content
📍 Public messages and local discovery
🗂️ Private notes, images, and documents connected to places
💬 Connections and chat
🌤️ Weather and air quality data
🎟️ Experiences nearby

But behind those features, there is also a lot of less visible work:

🔐 Privacy-focused architecture and encryption
⚙️ Backend services and data handling
📱 Responsive UX across devices
🧪 Testing and bug fixing
📝 Legal texts, moderation flows, and compliance questions
🚀 Deployment, hosting, performance, and reliability
📣 Positioning, launch preparation, and figuring out how to reach users

Some days are about building a feature that is immediately visible.
Other days are about solving a technical, legal, or product problem that no one will ever notice directly — but that still matters a lot.

That is one of the things I enjoy most about building MessageDrop: it combines creativity, engineering, product thinking, and a constant stream of new challenges.

The app is already live:

I’m still learning a lot while building it — especially about balancing product ambition with the realities of time, focus, and doing many different roles at once.

For other solo founders and indie developers: what part of building your product takes much more time than people usually expect?
