Juno is the AI journal that notices what you don't. You write, or just talk. Juno finds the patterns in your own words: what lifts you, what drains you, what keeps returning. Then it offers one small step you can actually take. Most journals store your thoughts. Juno reads them back to you. WHAT JUNO NOTICES • Patterns across your weeks, like the way your tired entries cluster on Tuesdays • What is quietly working: the habits that show up on your calmest days • Mood shifts connected to sleep, people, and the words you keep using • A monthly review that tells your month back to you as a story, drawn from what you wrote HOW IT FEELS TO USE • Write or speak a quick reflection. Thirty seconds counts. • Check in with your mood in one tap, with twenty moods to choose from • Chat with a companion that remembers what you have already shared, right down to the entry you wrote last Tuesday • No blank page: gentle prompts drawn from your own recent entries • Streaks that forgive. Goals built from your own words, not a template. • Widgets for your home screen, so a moment of reflection is one glance away • Wrote about Sunday on a Monday? Move any entry to the day it belongs to. YOUR WORDS STAY YOURS • Encrypted at rest and in transit • Never used to train any AI model. Not ours, not anyone's. • Delete your account and your data anytime WHY PEOPLE STAY Juno is not about writing perfect entries. It is about understanding yourself a little better each day. Whether you are overwhelmed, ambitious, stuck, or simply curious, Juno gives you a calm place to pause, reflect, and move forward. Journaling has long been linked to lower stress and clearer thinking. Juno makes the habit easy to keep: gentle reminders, prompts that meet you where you are, and a companion that pays attention so you can simply write. Juno is a companion for reflection, not a replacement for therapy or professional care. JUNO PREMIUM (SUBSCRIPTION REQUIRED) Writing new entries and all of the AI features described above (patterns, mood insights, the monthly review, the companion chat, prompts, and goals) require a Juno Premium subscription. Juno Premium is an auto-renewable subscription, billed monthly or yearly. New subscribers can start with a 14-day free trial; after the trial it renews at the price shown in the app unless cancelled at least 24 hours before the trial ends. Payment is charged to your Apple Account. Manage or cancel anytime in your App Store subscription settings. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is rating: Juno at 5.0 against Undertone's 4.5. Juno also leads on review sentiment (100% vs 75%) and update cadence (every 3 days vs every 5 days). Undertone's advantage is monetization model (ad-supported vs free with in-app purchases) and ratings volume (10 vs 1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Juno sells 10 in-app purchases, starting at $19.99 per month and Undertone sells 6 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.
Juno holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Undertone has 10 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of Juno's written reviews are positive against 75% of Undertone's.
Juno ships an update every 3 days, Undertone every 5 days. The most recent releases landed on October 8, 2026 and October 24, 2026 respectively.
