What's New in Opal

1.77

June 22, 2026

Hello Journalers, TOO MANY exciting updates for you in this one!! (I really should get more of a life...but alas) (1) Affirmations on your home screen (you can toggle these off in settings). You can also customize your own by long-pressing on the open affirmation card. (2) Moons: Now you can see upcoming big moons in your moon calendar! Date and time based on your geography for new, full, and quarter moons. (3) Meditations: Go deeper with your journaling with a pre-journaling meditation. (You can toggle this off and on in settings). (4) Scan your writing: Love the feel of pen and paper? Me too. Now you can get all of the prompts, guides, and analysis of Opal but still without losing the act of writing. (5) There's a new journaling paradigm I think you may love...especially if you enjoy voice journaling or prefer the feel of pen and paper. I'm calling it 'writing modes'. Basically when you open an entry you can either have a focused typing mode, voice, or writing flow (where you scan all your writing at the end to digitize and get an analysis). You should see it anywhere you write in Opal -- save & some tools have shifted around a little, but I'm hoping it's all more intuitive! Would love your feedback! Do you like it, do you hate it? Any feedback is super welcome. Send an email or join our Discord. I love to hear from you. As always, enormously grateful you're on this journey with me. Many, many more things to come. Warmly, Darby

I finally found the one!

I’ve tried so many journal apps and Murmur is amazing. The prompts are inspiring and keep me engaged with writing. The guides are thorough and help me dive deeper. The insights are great and I love the visualization tool and the burn it page. I look forward to working through more of the guides.

Aw thank you so much for taking the time to review us! It means the world. Your feedback makes this all so worthwhile, and we have so much more to come! Including more in-depth guides, better memory, and affirmations. Thank you for being on this journey with us. Warmly, Darby

The Best App for Personal Growth

I definitely would recommend this app to anyone looking to write all their thoughts down. I personally find the functions in the app to not only be helpful but also motivating. To be able to have an app that’s easy to navigate and to also push you to share your inner thoughts with yourself is hard to find. I find that if you download this app it will literally make your life better instantly because you are no longer just having a journal you are having a personalized Biopic for yourself. Highly recommend to anyone. One of the best apps on the iOS Store.

Love every single aspect of This app would love to be able to have a calendar and date my own entries. But I love the app overall.

Hi there! Wow this fills my cup and I'm so happy you're getting good use out of Opal! I love this suggestion! So if you tap the moon on the home screen, you can get a calendar of the days journaled (your moons that you've collected). I'll add a way to edit the date, and view the entries from the calendar. Thank you so much for the feedback! If you had any more thoughts or suggestions around the calendar feature (or anything else), I'd love to hear them! The discord community is great place to connect and share (find it in home - profile icon - under "Grow with Us"), or you can always reach me via email! Happy journaling! ;D Warmly, Darby
