Limit who can view your post, or share it with the broader Pump network. Pump is designed to be the easiest and most powerful way for founders to share compelling content with the people who matter most.

The best connecting app

It allows me to join any of my groups instantly and communicate with them without hold or merging. It’s like an open house. Come and go as you like. Text or talk or share photos and files. My family of 22 got on it all at once multiple times so far. It’s as if we were having a party. Great for personal or professional use as it’s completely secure.

The new wave of communication!

An awesome app! I use Chalk to keep in touch with friends and family. It’s been given me the convenient ability to communicate with everyone at once. Noticed, there were some UI bugs while navigating the app.

Excellent app for post COVID-19 world!

Allows for large group or small group conversations, sharing photos and texts. Let’s you create voice rooms for various contacts and those people can enter and exit or mute easily.
