I'm a solo app developer.
In the last few months I've shipped a Bible reader, an emoji game, and an AI outfit-rating app. Plus dozens of ideas that never shipped.
Here's what I've learned so far 🧵
Apple rejected my AI outfit app under Guideline 1.2.
The reason: when you compared two outfits, my app said "Look B wins."
Apple read that as ranking people, not clothes.
Fair point honestly. I removed every trace of "winner" from the app. 🧵
What I changed:
• no "wins" text
• no winner badge
• no bigger score or highlight colour on either look
Both looks now get equal visual weight. You get feedback on each, and you decide.
👗 FitCheck AI: rate your outfit, or compare two looks side by side.
Apple rejected it first. The reason surprised me (story coming tomorrow).
v1.0 is now live on the App Store.
I'll be sharing everything here:
• downloads & revenue
• rejections & bugs
• how I build fast with AI tools

Meet Alexandr Wang - Meta’s Chief AI Officer and the mind behind @muse. 🤖
He reportedly helped drive a staggering $200 BILLION in Meta value in just 10 days. 🚀
And the fit? 👕😂
Proof that you can wear whatever the hell you want to work.
What matters isn’t what you wear. It’s what you deliver.

Replying to @alexandr_wang
@alexandr_wang If one Muse is called a Muse… what do you call two or more? 👀
Muse²? Muses? A Muse Army? 😂

👀 @Mrwhosetheboss just reviewed Xiaomi’s foldable phone that launched months ago…
Now the big question: Who copied who? 🤔
Did Apple take inspiration from Xiaomi’s design… or Xiaomi copied Apple?
What’s your verdict? 👇
