Cognius helps you understand yourself. Take short personality and relationship tests, get a reading written from your own answers — not a score, but plain words about the way you actually live — and talk it through with a guide who remembers what you found. Private, thoughtful and never judgmental. Key Features: Tests That Read You Attachment style, stress responses, communication, empathy and more — over forty tests in the catalogue. Answer honestly; Cognius reads carefully. Your Reading, One Card at a Time Every result arrives as a deck of cards: one honest observation at a time, with room to say "that's me" or "not quite". A Guide Who Remembers Talk through what you found — by typing or by voice. Your guide keeps the thread: what you discovered, what you corrected, what is still open. Every conversation builds on the last. The Map of You Seven sides of you, each opening through a test or one honest conversation. Watch the picture fill in over time. Private on Your Screen No scores on your lock screen and no test names in notifications. What arrives on your screen stays yours. Why Cognius? Most tests hand you a label and leave. Cognius starts where the label ends: it explains what your answers mean for your relationships, your work and your days, and then stays in the conversation for as long as you want to keep going. Privacy First: Your answers and conversations are stored securely and processed by AI to write your reading and power your guide — with your consent, disclosed up front. Nothing is sold and nothing is shared for advertising. You can delete your account in the app at any time, and request erasure of your stored data at cognius.app/support. Subscription Information: A subscription unlocks the full reading, every test in the catalogue and unlimited conversation with the guide. Cognius offers weekly, monthly and quarterly plans. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. You can manage or cancel your subscription in your App Store account settings. Questions? Suggestions? Anything else? Let us know at support@cognius.app Disclaimer: Cognius offers self-knowledge screenings and reflection. It is not a therapist, not medical care, not a diagnosis and not a crisis service. If you are struggling, or having thoughts of harming yourself, please seek professional help. In the US: call or text 988 (Suicide & Crisis Lifeline). For immediate danger: 911 or your local emergency number. ********************************** Privacy Policy: https://cognius.app/privacy Terms of Use: https://cognius.app/terms Support: https://cognius.app/support

Verdict
The clearest difference is review sentiment: Juno at 70% against Cognius's 0%. Juno also leads on rating (4.8 vs 4.1) and ratings volume (11K vs 41). Cognius's advantage is update cadence (every 2 days vs weekly). On price, ads, 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. Juno sells 10 in-app purchases, starting at $4.99 per 7 days and Cognius sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Juno holds the better App Store score, 4.8 against 4.1. That said, the two scores are not equally well evidenced: Juno has 11K ratings behind it against 41, so its average is the more settled of the two. Written reviews point the same way: 70% of Juno's written reviews are positive against 0% of Cognius's.
Juno ships an update weekly, Cognius every 2 days. Both last shipped on November 1, 2026.
