Go Efficiency Case With Lock


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

    I have tried many other apps before but always end up uninstalling them. This is the most effective option so far. Nice to see an independent company making something that genuinely works!
