Prism

Prism is a productivity application focused on daily improvement and personal accountability. Do better in your work & personal life by building a habit of self-reflection.

Here's how to play:
➢ At the end of every day you'll get a reminder to grade yourself (Default time is 10PM but you can change this in settings)
➢ Reflect on what you did well during the day
➢ Reflect on what you feel you could have done better
➢ Pick 3 things to focus on for tomorrow
