Love this question @JackieStoss ! I highly recommend Stoic, a journaling app that I use daily. https://www.getstoic.com/. From their website:
At its core, stoic helps you prepare for your day in the morning and reflect on your day in the evening. In the process, we also guide you to journal with thought-provoking prompts, build better habits, track your moods, and more.
stoic offers guided journals that covers all aspects of life from happiness, gratitude, productivity, self-discovery, stress & anxiety, relationships, therapy, sleep, and so much more. Every week, we cover new themes and provide a new prompt each day.
