A. 1. Clear app cache: Go to Settings > General > iPhone Storage, find Prêt à Makeup, and select 'Offload App'. This will remove the app but keep its documents and data. Reinstall the app from the App Store to clear the cache and potentially improve loading times. 2. Restart your iPhone: Sometimes, a simple restart can help improve performance by clearing temporary files and freeing up memory.

B. 3. Check for background app refresh: Go to Settings > General > Background App Refresh and disable it for apps that you do not need to run in the background. This can help improve the performance of the Prêt à Makeup app.
