Description
All of the other App Lock applications provide just PIN and Pattern lock options to lock your apps and vault. Most of the time, our friends and colleagues can guess our PIN or Pattern by peeping over our shoulder a few times. Are your friends, colleagues, and family members guessing your PIN frequently? We provide the Ultra Lock app to solve your problem.
Apart from PIN and Pattern lock option, Ultra Lock provides the following unique lock options,
1. Hours and Minutes PIN: This option sets the current hours and minutes as your lock screen PIN. For example, if the current time is 10:50 AM, then your lock screen PIN will be 1050. Since hours and minutes in the cellphone changes every minute, your PIN will also change every minute. The best part is, you needn't remember the ever-changing PIN.
2. Date and Month PIN: If you don't want to change your lock screen PIN to every minute, you can make use of the Date and Month PIN which changes to your lock screen PIN to the current Date and Month. For example, if the current date is 06/05/2018 in MM/DD/YYYY format, then your lock screen PIN will be 0506. On the next day, the PIN will be 0606.
3. Battery and Battery PIN: Battery and Battery PIN will set your lock screen PIN as the current battery percentage on your cell phone. For example, if the current battery level is 50% then your lock screen PIN will be 5050.
Apart from them, Ultra Lock provides the various combinations of the Hours, Minutes, Date, Month and Battery level such as Minutes and Date PIN, Month and Minutes PIN, Hours and Date PIN, Minutes and Battery PIN, etc., Using them, will make it tough for others to guess your App Lock password.
Other Cool Features in the app,
1. Time-Based Lock: You can enable or disable the lock for a particular set of apps based on the time. For example, you can lock your social networking apps only during your office hours from 9 AM to 5 PM and unlock it after that time.
2. WiFi-Based Lock: You can enable or disable the lock for a particular set of apps based on your connected WiFi. For example, You can enable lock for Messaging apps when you connected to your office WiFi and disable lock for them when you disconnect from that.
3. Intruder Detection: The app will capture the photo using the front camera if someone tries to access your locked apps and show a notification about it when you unlock the lock screen next time.
4. Last Unlock Time: Ultra Lock will show a notification with the last opened time of the locked apps when you unlock the particular apps.
5. Lock PIN Modifiers: We provide reverse and offset modifiers which hardens the task of guessing your PIN. For example, If you use the reverse modifier option Hours and Minute PIN type and the current time is 12:15 PM, then Ultra Lock will set the lock screen PIN for the App Lock as 5121 which is reverse of the current time.
6. Random Numeric Keypad: The lock screen of the App Lock shows the numeric keypad in random order.
7. Photo and Gallery Lock: You can lock your private photos and videos inside Ultra Lock.

Why it is suddenly unavailable on iphone. I have loss lots of photos and work things from this app. Its says unable to download on my iPhone. Atleast they have to send some notice to the users so the users can remove their personal things from this app to another place. But not it's just says delete the app.

What kind of app is it ?? I added photographs to its vault and now there is no way to get them back out of this vault ?? If anybody wishes to change his app lock then ?? That means it has been made by such a cheap intention.......

First opening the app that asked me for a 4-Digit password play get asked me for the second time. I don't know if this is an app that can be used with a remote management app what I have remote Management apps on my phone that I cannot remove seems like every time I use any app is version one example 1.4. Or 1.2.78. I thought Google Play Store has been around long enough all the versions of the apps are above one?
