SafeDrunk

Don't regret the morning after drinking.

"Buying strange things on shopping apps..."
"Posting weird things on social media without any memory..."

Have you ever felt that despair the morning after a fun night out?
SafeDrunk is an app that physically locks "specific apps" before your judgment fades, preventing your drunken mistakes.

Recommended For

  • Those who often lose their memory after drinking
  • Those who have made mysterious purchases the morning after drinking
  • Those who tend to post emotional messages on social media late at night
  • Those who want to do a digital detox and focus on conversation
  • Those who want to concentrate on studying or work (also useful for preventing temptation)

Key Features

1. Complete Block of Designated Apps

Select apps you don't want to use while drunk, such as SNS or shopping apps, in advance.


With just one button, it locks the launch of the apps until the set time the next morning.

2. "Calculation Test" Required to Unlock

To unlock, you must correctly answer 5 consecutive complex calculation problems (e.g., up to 3-digit multiplication).


By setting the difficulty level high enough that you can't solve it when your judgment is impaired, it physically prevents accidental use.
