Starply
Read full descriptionHide full description
Starply holds two kinds of writing. One is sending stars to your future self. Answer the question that surfaces today and send it off as a star. A month or a year later, it arrives again. By then you've changed a little, so you write back to who you were and leave a new question behind. Slowly, letters travel back and forth between you and yourself. On days when writing feels hard, leave your voice instead. Hearing yourself again, long after, brings that day back more vividly than anything you wrote down. The other is simply today's diary. It doesn't have to be grand. One line about your day and one mood is enough. Your moods and energy build up as colors on the calendar, and the stats show at a glance how you've really been doing. The stars you've sent stay up in the night sky. The farther away one floats, the longer until it arrives. Sometimes just looking up at that sky is enough to quiet your mind. If you find yourself wanting to write more often and at greater length, there's Starply Premium. Basic journaling and opening the stars that arrive are always free. Write down today's heart. For your future self, and for who you are today. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
