How I mapped 600+ GPS audio-guides as a solo dev (and why I finally did it after 8 years)


Building a travel tech app wasn't just a coding challenge for me (i barely know how to code); it was a way to process grief.

Eight years ago, I wrote down a business canvas for an app that would kill the traditional "guided tour". I hated rigid schedules, and I hated arriving at a beautiful natural trail only to find a faded tourist sign from 1998. I wanted a pocket guide. But life got in the way, and the idea stayed in a drawer.

Recently, I lost my mother. She was the person who instilled in me a deep curiosity for the history that surrounds us. Grieving is a strange process. For me, it meant finally sitting down, opening my IDE, and turning that 8-year-old idea into reality as a tribute to her.

I built YouGuide: a mobile app that uses background geolocation to trigger audio stories. You put your headphones on, lock your phone, and walk. When you reach a historical monument or a trail, the app tells you its story.

As a solo dev from Argentina, the challenges were huge:

Data Collection: I manually mapped and curated over 600 historical and natural points across 90 cities.

UX/UI: Designing an interface meant to be ignored (the goal is for users to look at the landscape, not the screen).

Whatโ€™s Next?
I just launched the Beta version (it's 100% free). My current stack relies on tracking early user events to see where the drop-offs are during the onboarding flow.

Building in public is new to me, but I wanted to share this milestone. If you are building geolocation apps or just love traveling, Iโ€™d be incredibly grateful if you could check out YouGuide and give me your most brutal feedback.

Link to the project is on my profile. Thanks for reading!
