GoGrateful

GoGrateful is a digital gratitude journal based in your text-messages. So you don't need to download anything. You'll get a text in the morning & evening asking you to write what you're grateful for, and each journal entry will be securely stored in your account to access whenever.

Practicing gratitude is well researched and has many benefits such as increasing happiness, enhancing positive emotions, and increasing your overall psychological well-being.
