Dynamic pin for Android
When you type the same PIN every time, there is a good chance your friends , electronic surveillance or others knowing it . How will you avoid that ?
Dynamic Pin changes the pin based on an expression you set in the application. After every use, the pin is destroyed and new pin is generated. Only the user, who know the expression can evaluate the new pin. Deducing the expressions from pin is not a trivial task .
You can set any expression like a+d , a*f , g-c ...
If you are interested in only app lock ,

LOLLIPOP users have to manually enable app usage access for app lock via Settings--General--Security--App Usage Access.
App lock is available for all devices.
Screen lock is available for 4.2+ devices. Screen lock for Lollipop will be added shortly.
Notification details about matrix will appear on every restart.
Apps unlocked remain unlocked till screen goes off.
SCREEN LOCK IS FOR NON-ENCRYPTED DEVICES ONLY.
KINDLY NOTE PIN IS SET AS 0000 DURING VALIDATION .
***If your expression encounters divide by zero , the result is zero .
In HTC and Sony devices, matrix will be shown when Emergency Call is clicked on the lock screen.
By default numbers used in the matrix are binary , only 0s and 1s . So pin varies among 0000 , 0001 and 0002 . You can change this option to use single digit numbers ( 0 - 9 ) .
Basic Pack :
Unlimited app locks.
This pack enables operations among the matrix elements using + , -(~) , * , / , % , ^ .
Examples :
(a*d)+5 - Multiply corner elements of the first row and add 5;
(a+d+m+p) - Add corner elements of the matrix.
Advanced Pack :
This pack enables MIN (a,b), MAX (m,p) functions along with basic pack features.
More functions are planned for future releases.
Examples :
MIN(a,d ) - Minimum value between a and d .
MAX(a,b ) - Maximum value between a and b .

By default , screen lock is automatically removed after 5 consecutive incorrect attempts . You can change this option in Dynamic Pin - > Recovery -> Auto screen unlock attempts . After specified incorrect attempts, app removes dynamic pin screen lock.This option can be disabled by selecting required attempts to "Infinite". This feature is device specific.
Its amazing
Some time cannot display the unlock chart please fix it immediately...
Great app but needs to be longer then 4 digits long to stand up to brute force attacks. Sound concept though.
I like the app and the idea behind it but I cant get it to work with the lock screen. Could use some work
I buy basic verion of this application... But it is not working in my LG G3 for application lock purpose. I changed the administrative option in security also. I can't find the app usage in settings- general- security... Please check on LG G3 and reply
"Screen Lock for Lollipop will be added in a week." How many days is a week in your timeline?
Important to do: When setting the software as administrator, also check to enable widgets. Then, maybe when testing, swipe to go left and add the widget with all 0s as the pin. Otherwise, like me, do it later while trying to guess the pin. But it works now, and I am happy. Would just like the instructions cleaned up a mild but, I hadn't added a lock screen widget before, so I learned something new and got a great new pin. Thanks. :)
I wish there were more algorithms and it doesn't work for the lock screen on lollipop. I really only got this for the lockscreen.
Validation code does not show on lock screen moto e2nd gen
An earlier update had broken this app, but the latest update fixed them all. The developers were very responsive and fixed the issue quite quickly......
Hey good evening, I am laison. I am a basic value pack user of your application. This application is working amazing and ideas so good. I just noticed one problem regarding the unlocking and attached screenshots through the mail. How to uncheck permanently option regarding about "unlock all dynamic pin locked apps". I am able to uncheck but when the application is restart or turn up from the screen sleep directly go to checked for that option I expecting a reply from you.
The app - and all its settings - are a bit too complicated. There also need to be more complex expressions to choose from. In effect, it is a paid app.
Verification code doesn't show up on the Lock screen. Samsung Galaxy Note 3, Android Lollipop
Using an LG G3, non of the apps are locked. I even bought the advanced pack but it doesn't lock the apps. Please fix it
Verification code does not show up on the lock screen sony xperia z
Awesum dude.. gr8 work... keep it up
I download this app after being notified that the issues were resolved and I am honestly pleased with the way it works. It's great as it can lock certain apps individually as well as the whole phone. This is a mixture of good and complex security.
Its wonderfull seccurity app...
Giving this lock app a second try and having better luck. I like the one-time use PINs.
The app locker is really unique and almost foolproof. Eagerly waiting for the lollypop update.
I was searching for a good app lock application. I found this one closest to being petfect
Nice
Got locked out of my phone and had to do a factory reset because the key table will not show up on my lockscreen. Needs a default pin option
This is a difficult app to figure out if you're not super tech savvy. If you set the home screen lock you can't see the grid! I was locked out of my phone, pressing all kinds of numbers until finally it unlocked. I will uninstall while I have the chance.
Can't wait till it's compatible with lollipop
simple and wonderful app to have on a smartfone.. u have to experience it to feel it.. give it a try
Liked it, matrix display overlaps in 1+. Correct that one.
Good use of our brain..!! Cant track the PIN so easily without knowing the formulae...
Good one dude.
Very good
Great App,Especially when u have family and friends who jus love to invade our privacy
The developers have really responded to the issues faced by users and have worked to eliminate them in their app. Now no longer do I have to enter the pass code every second or so, and that's a big development if you ask me. Though there are a few more kinks to iron out, but overall the app just works. Kudos to the developers.
ABCD
Ultimate creativity. There is always uncertainty and complete security about the PIN. I wonder how no one thought of this b4. Keep it up

One of the best app lock available in market.
Security purpose good app.
App looks great, but I'd like to see some bug fixes and improvements to the text in the app, it's a bit hard to understand. Making the widget look a bit more natural would be nice as well. Great app overall! I've been waiting for something like this for a long time.
