What’s the hardest part after your app is built and live?

Hey founders,

I’ve been chatting with a bunch of people launching apps lately and noticed something interesting:

Everyone talks about building an app… but almost no one talks about what comes next.

• You get it on the App Store or Google Play.
• Users download it.
• And then growth, retention, and iteration suddenly feel like a full-time job.

I’m curious:

• What has been your biggest challenge after launching your app?
• Do you struggle more with user growth, retention, or iterating features?
• How do you approach deciding whether to pivot your app or double down on the current idea?

Would love to hear real experiences — not looking to sell anything, just trying to understand the landscape.
