Use adfinito to set up "clocks" which are basically countdown timers that are set around a date and time. You simply set up as many clocks as you want, when you want, and then either broadcast them to the world or send them privately to a selected crowd of people. It takes less than a minute to set up a clock and share it. Once it is live anyone can use the app for messaging to anyone that can view the clock. You simply click on the message icon to see the message thread for a particular clock.
When the clock runs out then it simply disappears from view.
It is really simple and easy to use. You will need to set up an account to publish and message through adfinito which takes less than a minute. Once you have set up your account you can start creating clocks to share with others straight away.
If you want to share clocks with one person or a group of people you need to set them up in a crowd. Your personal clocks are end-to-end encrypted meaning no one outside of your crowds can read them including all of us at adfinito.
