Set screen time

if you want to limit how much time you, or someone else, spends on certain apps then you can set a screen time. Go to settings>general>accessibility and then scroll down to ‘Guided access’. turn the feature on and then select ‘time Limit’ to choose an end tone before quitting out and opening the app you wish to limit. triple-tap the Home button, choose ‘Options’ and then set a time limit. When this expires you can no longer use the app.
