On Apple devices, there is a setting that enables the timeout for the requirement to put your lock pin back in. For example, if I set it to 5 minutes, once I unlock my phone, it will remain unlocked for 5 minutes and I can go directly into phone without unlocking again until the screen is off for five minutes. Normally, where it is now, I must unlock every time. I would like to know if there is app to do this, so I don't have to unlock all the time. Sorry for poor English, it is not my native language, thank you.
