Grateful is a gratitude app with a simple social layer.
You write a short entry, keep it private or share it to a circle. A circle is a small private group of your own making — family, close friends, whoever you'd actually want to hear from.
It shows you the most recent post first. People in the circle can react or leave a comment. There's also a daily notification that sends you something you were grateful for in the past.
Try it out on both iOS and Android. Go to grateful.so
