A sun tracking app hit 10K downloads and reached $8K MRR using a simple faceless video format.
The app is called Sunlitt.
It uses AR to preview sun direction and shadow coverage in a specific location at a certain time. It was built for creators and explorers, but went viral by aiming straight at photographers on TikTok.
On December 4, Sunlitt was ranked #215 in the U.S. Weather category.
By December 5, it jumped to #7.
Now it sits in the top 100 for Weather in most countries.
That rise aligned with a single faceless TikTok video.
@goldenhourgirlll uploaded a video with the hook:
It pulled 650K views and 11.6K saves on Dec. 4.
The video is a visual app demo.
It shows Sunlitt’s shadow map over Central Park, letting users preview where shadows will fall at a specific time, directly in AR.
@goldenhourgirlll is still posting similar videos, trying to reproduce the same virality.
In format terms, the loop is simple.
Problem POV → visual proof → save utility → distribution.
They took the product to a market where timing matters (photographers), named the pain point (“harsh sun”), and the value became obvious.
