Need a place to write down all your thoughts, ideas, and reflections? Meet Scribble - a bullet journal designed for creating short, concise entries. Scribble is perfect for people who wish to record their thoughts, but don’t have the time to sit down and write a long journal entry. Use Scribble whenever you have a thought that’s worth remembering and categorize it into a relevant journal/tag to easily find it later. One of the benefits of microjournaling over traditional journaling methods is that by writing down your thoughts in the moment, you get a more accurate picture of your thought process throughout the day. FEATURES: CATEGORIZE YOUR ENTRIES INTO JOURNALS You can assign each entry to a specific journal/topic. This will color code your entries to the journal’s corresponding color and make your entries easier to organize. (i.e. Ideas, Goals, Insights, Dreams) ADD TAGS TO FURTHER ORGANIZE YOUR ENTRIES You can also assign multiple tags to each entry to help further categorize each entry. This can be helpful if you wish to have subcategories in each journal. FAVORITE ENTRIES Add a heart next to your most important entries to help highlight them for easy access later. VIEW ENTRIES FROM ANY DATE Jump to a specific date to see all your entries at different points in time. QUICKLY FILTER YOUR ENTRIES You can quickly filter your entries by any combination of journals, tags, and more. Tap on any label to add that filter, and only see entries matching those filters LOCK WITH TOUCH/FACEID Keep your entries private by locking your journal with Touch/FaceId. You are still able to create new entries while your journal is locked to help make using Scribble as quick and easy as possible. SCHEDULE REMINDERS FOR YOUR ENTRIES Add a reminder to any entry and schedule a push notification for a specific time. Visit the Reminders screen to see all entries with a reminder, and mark them as complete when necessary. **Note from developer: Thanks for being one of the first users of Scribble!

Opal is a guided journal and diary to delve deeper: why you react the way you do, what you actually want, what your dreams keep trying to show you. Pick a guide from a large free library, follow a ten day series, or open a blank page and write whatever is on your mind. A FREE LIBRARY OF GUIDES Browse guides on finding clarity, purpose and direction, relationships, attachment styles, limiting beliefs, Stoic philosophy, gratitude, and more. Each guide walks you through a sequence of questions, with an example answer beside every prompt so you always have somewhere to begin. TEN DAY SERIES When you want a longer practice, start a series. Shadow Work spends ten days with the parts of yourself you usually avoid, from the inner critic to the golden shadow. Deep Manifest helps you name the desire underneath the goals you keep setting. The Dreaming Life teaches you to record your dreams and follow the figures and images that keep returning. A new day appears on your home screen each morning, and each one builds on what you wrote before. GUIDED AUDIO JOURNALING Some pages open with a short recorded practice. Press play, close your eyes, and let a memory or an image surface. When the audio ends, write about what came up and where you felt it in your body. Ambient soundscapes are there too, for when you want rain or low tones behind your writing. WRITE YOUR WAY Type, talk, or write by hand. Voice entries are saved as tapes you can replay, each with a transcript you can read back. Add photos to any entry, and keep separate journals for the different threads of your life. CONNECT DOTS ACROSS TIME Opal reads across your entries and shows you what it finds: recurring themes, emotional patterns, relationship dynamics, dream symbols. Each week, month, and year it assembles a reflection drawn from your own words, shows you the passages it relied on, and keeps it in your archive. You can also ask your journal a question and get an answer grounded in what you actually wrote. PRIVATE BY DESIGN Your writing is stored on your device. No account required, no cloud sync by default, no data sold. Lock Opal with a password. When you use an AI feature, names, places, and other identifying details are masked on your phone before anything is sent, and you decide how much context is shared. Your entries are never used to train AI models. Export or delete them whenever you like. ENDORSED BY THERAPISTS "Opal encourages deep self-expression and deep self-acceptance while also giving tools for change."
