Clear cache on iPhone for third-party apps
Clearing the cache of third-party apps varies from developer to developer. Some like Slack offer an option in the app preferences in iOS Settings, while others like Facebook don’t. Check out the settings of your apps to see your options.
For apps that don’t provide a clear cache button, deleting the app and reinstalling it is the next option.
You can always take a look at Settings → General → iPhone Storage to prioritize which third-party apps you may want to tackle first.
- How to Clear Cache on iPhone and iPad Safari
- Open Settings
- Swipe down and tap Safari
- Swipe down again and tap Clear History and Website Data, tap it once again to confirm
Alternately, if you’d like to clear data from individual websites, without clearing the entire Safari cache, tap Advanced, Website Data, then Edit.
