If apps keep crashing on your iPhone, the cause is usually low storage, bad app data, an iOS compatibility bug, or performance strain elsewhere on the device.
Quick answer: Update the crashing app, restart the iPhone, and make sure you still have healthy free storage. If several apps crash together, compare the issue with iPhone lagging and freezing and slow performance after an update.
Why this happens
Most iPhone app crashes come from one of four buckets: damaged app data, low free space, an app that needs an update, or wider system instability caused by heat, battery wear, or a buggy iOS build.

FAQ
Why do apps crash more after iOS updates?
Because apps often need compatibility patches after a big iOS release.
Can low storage make apps crash?
Yes. iOS needs free working room for cache, updates, and saved files.
Will reinstalling an app delete my data?
Sometimes. Cloud-based apps usually restore data after sign-in, but some offline apps do not.
