Lock on, distractions off

Lock on, insomnia off 

The blue lights from smartphones can lead to sleeping disorders, which can seriously impact on your memory, cognitive and learning skills. You are a click of a button away to sound sleep with Goefficiency.

Lock on, depression off 

Users tend to compare themselves unfavourably with their peers on social media, promoting feelings of loneliness and depression. Goefficiency can solve that problem.

Lock on, performance on 

The device will enable you to save a great deal of time on a daily basis. It takes no effort but reaps significant rewards. Will power externalised. 


Compare to phone addiction apps, how effective is this product?

An app is not effective in keeping the phone distraction away since it can be exited or uninstalled anytime. While the timer is on, Goefficiency doesn’t allow you to use your phones. Hence it is a highly effective solution for countering phone addiction.

This is very easy to use.  Once the phone is locked the world seems to quiet down. I do not need to play my phone to sleep and wake up. My sleep quality has greatly improved.  I need my phone at work but I used Goefficiency regularly at night. It is a total time saver.

This is the best invention ever! I can concentrate so much at work now and my productivity has soared. I have tried many other Apps before but you always end up uninstalling them. This
is the most effective option so far.

I gave it to my 16-year-old son this product, and he loves it. At a young age, he has weak self control. Finally, he has the time to complete his homework on time.
