Hi Jerry,
Many thanks for your story. I haven't heard of some of these apps that I will definitely use (Streak) and maybe Calendly.
Have you heard of Brain.fm? It is also available for iOS, at least. It was developed by scientists that figured out which tones had the desired effect on brain waves being measured in real time. The end of this study is the app.
Best regards,
Scott
