What are the biggest mistakes that cause mobile apps to crash or fail after launch?

Most post-launch failures happen because of 5 avoidable mistakes:

1.     No scalability planning

2.     Poor backend optimization

3.     Ignoring real-user load testing

4.     Overcomplicated feature sets

5.     Weak QA processes

Common scenario:
App works perfectly in staging → crashes with 10k real users.
Why?
Because staging ≠ real traffic patterns.
Best practices:

·        Use load testing before launch

·        Design API architecture for scaling

·        Keep initial features lean

·        Monitor crash analytics daily

Scaling isn’t about adding servers - it’s about planning infrastructure early.
