Clear an app's cache
Many apps that stream or download — music, video, podcasts, social apps, browsers — have a Clear Cache or Storage option in their own settings. Removing offline downloads there frees the most.
Delete and reinstall an app
- Open Settings › General › iPhone Storage and tap the app.
- Check Documents & Data — that is the app's cache and its saved files together.
- Make sure anything you need is backed up or synced to the app's account.
- Tap Delete App, then reinstall it from the App Store. It starts with an empty cache; sign in again.
What a cache cleaner app can do
On iPhone, every app keeps its cache in its own sealed space, so a “cache cleaner” cannot reach other apps' files, whatever its name says. What a cleaner can do is free the space you control — usually far more than any cache.
Cache and System Data
Caches iOS keeps for itself are counted as System Data. Restarting your iPhone often makes it smaller; it also shrinks on its own when iOS needs room.
