Dubbed as LastTimeUnlocked, this new Cydia tweak knows the answer for question how to know when my iPhone was last unlocked by showing you exact time right on your device Lock screen, so you can’t miss it at all. As shown on the screenshot example below, LastTimeUnlocked tweak displays a convenient little timestamp at the bottom of the Lock screen, showing you when your smartphone or tablet was unlocked. Using this info you can easily find out whether or not someone is snooping in on your device, allowing you to take subsequent action later on.
Here is short review on how the LastTimeUnlocked tweak works and how to know when iPhone was last unlocked.
To get started you should grab the tweak for free from Cydia’s BigBoss repo. LastTimeUnlocked supports all jailbroken iOS 10 iPhones and iPads and comes with dedicated preferences pane in the Settings app. From there you can turn it on or off on demand and change the text string:
Because you can change the text string manually, it is possible to easily change the language to anything besides English. You can even set the text to something inconspicuous so no one else can guess what the timestamp actually means.
LastTimeUnlocked tweak will be useful for those who have a ‘family-oriented’ device, such as an iPad, that everyone shares. For parents, this will serve as a way to know if the iPad is getting used by kids during hours when it shouldn’t be.
If you have this idea that someone might be breaking into your iPhone behind your back, then it’s a no brainer to install this little package right away. With just a lone toggle switch and a way to customize the text, this tweak is really easy in use. Personally I like the way the information is displayed on my Lock screen: the text doesn't occupy a lot of space and doesn't covers any other element of the Lock screen.
