Two weeks ago i launched Sign, an iOS app that turns your home into a 3D Wi-Fi map.

Solo dev, first real launch.

How my app works:

you walk through your rooms with your iPhone.  
LiDAR builds a 3D model of your home live while the app samples your Wi-Fi (signal + speed) as you move.

You end up with a dollhouse view of your actual apartment with the signal painted on it ( with dead zones in red).

Every room gets a score, and it tells you where to move your router, or where an extender would actually help.

# The story so far:

Aug 4: submitted to Apple. Rejected : missing EULA link in the description. Fixed same day.

Aug 7: approved. Live in the US.

Week 1: first paying users.

Aug 15: 143 installs in ONE day, from 25 countries. (I guess mostly from AppStore)

Aug 19: v2.1 rejected over ONe word. A button said  
"Allow", Apple wants it to say "Continue".

Asked for the bug-fix exception → approved the next day, without resubmitting.

Today: 500+ downloads, most of them in the last 7 days. $O spent on marketing.

Built mesh support and multi-story homes - the two most requested features so far.

Goal: 50 paying users by Sept 30.
