Reached 500 App Store users in 5 days. What worked, what failed, and what I plan to do next?

I recently launched my AI face analysis app Aesthetica on the iOS App Store and reached 500 users in five days so I wanted to briefly share what drove early traction, what I learned about ASO localization and organic outreach, and what I am focusing on next.

I am a solo indie developer learning by shipping fast, improving through real user feedback, and proving that launching an imperfect MVP beats waiting for perfection, so feel free to ask anything or share your own experience.
