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.

Verdict
The clearest difference is ads: Opal at none against Notebook's shown. Opal also leads on review sentiment (100% vs 72%) and rating (5.0 vs 4.7). Notebook's advantage is ratings volume (14K vs 38). On price, update cadence, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Notebook sells 1 one-off in-app purchase and Opal sells 1 in-app purchase, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.
Opal holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Notebook has 14K ratings behind it against 38, so its average is the more settled of the two. Written reviews point the same way: 72% of Notebook's written reviews are positive against 100% of Opal's.
Notebook ships an update weekly, Opal every 2 weeks. The most recent releases landed on November 7, 2026 and November 5, 2026 respectively.
