Just Be, a mindfulness reminder application

I’m proud to announce that I’ve developed an Android “mindfulness reminder” app named Just Be. While this new app is simple in many ways, it does what I want: It sends me periodic reminders that help me return to the present moment. (The “reminders” are Android notifications.)
