Couchgram allows you to protect your phone and your privacy at the same time. For example, if there is an incoming call from a certain person, you can set up a lock so that a pin number or unlock pattern must be entered before the call can be taken. You can lock and password protect numerous things from your calls and texts to your photos and phone settings.

A modern toolkit for Smartphone privacy and security

Couchgram has enough security features to allow you to lock up your phone from all but the most nosy and determined intruders. The app lock stops others from getting to your apps, and the incoming phone lock means only you may take certain calls. Hide caller IDs or rename them, and automatically delete your call logs. Boost your phone's memory and speed up your phone at the same time. If you lock your phone with the app, then it is completely secure. However, if you only use the Couchgram app to lock certain functions on your phone, then a nosy person may simply uninstall the app in order to reach your previously locked functions.

Hide whatever you are doing that you don't want others to see

One of the most obvious reasons why you may like this app is if you have a partner and you are cheating, but it may also be used to hide the fact you are working two jobs, and to stop people finding out what you do with your spare time. Lock the phone with a password pin or with a pattern that you enter before you use an app or see your text messages. It is not a foolproof app for cheaters, since your partner may ask why everything on your phone is locked down, but it is certainly handy for people who frequently share their phone or leave their phone where others may get at it.
