The Comic Relief  swear jar app

How does the bloody thing work?

To begin, simply choose how much you’d like to donate. The app will then identify every time you swear for the next 10 minutes (or less if you want), using voice recognition technology from Google. For every swear a donation of 20p will be made from your pot. Once you’re time is up, see how you fare against other swearers using the app by checking out the ‘Wall of Shame’.

Make your profanity matter

The Swear Jar is more than just an app for potty-mouths like yourself, it helps to change lives.

The cash raised from your swears will help to fund Comic Relief projects that make a massive difference to countless people living really tough lives in the UK and some of the world's poorest communities.
