Coherent Mind
Mystical Experience & Journal
$6.99 · Designed for iPad. Not verified for macOS.
Measure your mystical experience with the MEQ30. Record substance, dose, and reflections. See your patterns through graphs and heatmaps.
Coherent Mind is a private journal for the experiences that are hardest to put into words. Log a journey, describe it with the validated 30-item Mystical Experience Questionnaire (MEQ30), and see how your experiences change over months and years. Everything stays on your device, behind Face ID.
THE MEQ30, WORD FOR WORD
The MEQ30 is a research instrument used in studies at Johns Hopkins, NYU, and Imperial College London to describe mystical-type experiences, whether they come through meditation, breathwork, or a guided session. The app reproduces its 30 items and 0–5 response scale exactly as published, and scores four factors: Mystical, Positive Mood, Transcendence of Time and Space, and Ineffability. When all four reach 60 percent of their maximum, the journey is flagged as a complete mystical experience, the threshold used in the research literature. The questionnaire describes an experience; it doesn't grade you.
TWO COMPANION INSTRUMENTS
• Challenging Experience Questionnaire (CEQ): 26 items across seven dimensions (fear, grief, physical distress, insanity, isolation, death, and paranoia) for the difficult side of an experience.
• Persisting Effects check-ins: four questions at 30 and 90 days after a journey, so you can record what stayed with you.
A JOURNAL FOR EVERY JOURNEY
Record the date, setting, intentions, and notes before and after. Substance and dose are optional free-text fields. Add tags, and keep a voice memo of up to 30 minutes with optional on-device transcription. Saving a journey offers the questionnaire rather than starting it, so you can come back to it when you're settled.
SEE YOUR PATTERNS
• Factor trends and total score over time, with complete experiences marked
• A journey calendar where deeper color means a higher score
• Substance summaries and dose-response charts across the journeys you've logged
Tap any point on a chart to open that journey.
INNER WORK (OPTIONAL)
A structured shadow-work journal shaped by Internal Family Systems and Jungian practice. Record Shadow Encounters in five optional steps, follow the Parts that show up across journeys, and set integration commitments with check-ins at 7, 30, 90, 180, and 365 days. Inner Work sits behind its own lock, can be hidden entirely, and is left out of every export unless you choose to include it. Any Part can be sealed under its own passphrase.
PRIVATE BY DESIGN
• No account, no ads, no analytics, no third-party servers
• Every entry encrypted on your device; Face ID, Touch ID, or passcode to open
• Optional sync through your own private iCloud
• Encrypted backups you can restore on a new iPhone
SHARE ON YOUR TERMS
Export a single journey or a date range as a password-protected PDF, or your full history as CSV (encrypted by default) for your own analysis. The clinician export turns one Part or one Shadow Encounter into a password-protected PDF for your therapist or integration coach, in your own words.
SOURCES
The 30-item MEQ was derived by MacLean, Leoutsakos, Johnson, and Griffiths (2012) and validated by Barrett, Johnson, and Griffiths (2015). The CEQ is from Barrett, Bradstreet, Leoutsakos, Johnson, and Griffiths (2016). Full citations, and what the app took from each paper, are in Settings → About.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Version 2.4 is a visual release. Nothing about what the app records, stores, or shares has changed; what changed is what sits behind it.
• A new backdrop. The brown brain illustration is gone. Every screen now sits on a deep indigo starfield with a faint halo of rings, in the same palette as the app icon. Cards, lists, and sheets were re-tinted to match; the gold accent and the four factor colours are unchanged, and body text still clears the same contrast bar it did before.
• The backdrop shows everywhere again. On recent iOS 26 releases the brain had quietly stopped appearing behind the main tabs, leaving plain black behind Today, Journeys, Trends, Inner Work, Settings, and anything opened from them. 2.4 draws the backdrop on each of those screens directly.
• The launch screen now matches the app, so opening it no longer flashes white on a light-mode device.
• Reduce Transparency still swaps the art for a solid dark colour, so the translucent surfaces stay on an opaque base.
No new permissions in this release, backup files remain compatible in both directions, and nothing stored changes shape.
