Adding the Smart to Smartphone

Presense takes the guesswork out of contacting other people, effortlessly.

Call, Text, IM, or Email?

Easily see if someone is busy at the moment you want to contact them so you can pick the best way to reach out.

App Integrated

See the availability of others right from within the apps you are already using today: Mail, Messages, Phone, WhatsApp, and more.

Time Saver

Regain precious minutes throughout the day by not trying to contact people who have indicated they are busy.

It's what's next in digital communications.

In an era of self-driving cars and smart toasters, we still blindly try to contact people like we have since the dawn of the telephone.

With today's technology, it is now possible to know if someone is likely to be busy before you even try to contact them.

Presense aims to equip you with this information in a subtle way, requiring no changes to how you work or use your phone.
