Write through it. Privately. Then see what your body already knew.
MindLens AI is a journaling app that reflects with you using Apple's on-device intelligence — never the cloud. Your words are encrypted on your iPhone, your patterns surface from your own Health data, and the hardest moments are met with real support. Calmer, more self-aware, and genuinely yours.
Sound familiar?
Your journal is on someone's server
Cloud AI journals send your most intimate thoughts to third-party servers — subpoena-able, breach-able, gone from your control.
You journal, but nothing connects
You write how you feel, but never learn why — no link between the foggy weeks and the sleep, stress, or movement behind them.
Generic prompts, no real technique
"How was your day?" isn't therapy. Most journals have no structure, no evidence-based method, no way to actually reframe a spiral.
Apps that miss the dark moments
When it matters most, chatbot journals keep chatting — instead of stepping back and pointing you to real human help.
Everything you need
On-device AI reflection
Apple's on-device model reads your entry and offers a warm, CBT-informed reflection — summary, thinking patterns, and gentle reframes. No cloud, no inference cost.
Provable privacy
Every entry is encrypted with a key protected by your iPhone's Secure Enclave. There is no server to subpoena — your journal physically cannot leave the device.
Mood-to-biometric insight
MindLens quietly correlates your mood with sleep, HRV, and exercise from Apple Health — so you finally see why some weeks feel foggy.
CBT / DBT / ACT toolkit
A clinician-informed library of thought records, distress-tolerance skills, and defusion exercises you can practice between entries.
Crisis-aware, always
If you write something heavy, MindLens steps back, suppresses the AI, and surfaces real human support — 988 and the Crisis Text Line — instantly.
Shame-free streaks
Miss a day? Your streak rests, it doesn't break. No red badges, no guilt. Built for the hardest evenings, not a leaderboard.
Built for power users
The anxious optimizer
Write through the 9 PM spiral, get a calmer perspective, and confirm whether your body data agrees — so tomorrow starts lighter.
Between therapy sessions
Keep practicing the CBT and DBT skills your therapist taught you, with structured thought records you can bring to your next session.
The quantified-self journaler
Years of Health data, finally given a narrative — see which lever (rest, movement, stillness) actually moves your mood.
Frequently asked questions
Does my journal really stay private?
Yes — structurally, not just as a policy. The AI runs on your iPhone using Apple's on-device model, and your entries are encrypted with a Secure Enclave-protected key. There is no MindLens server, so there is nothing to subpoena or breach.
Which iPhone do I need?
MindLens runs on iPhone with iOS 26. On-device AI reflection uses Apple Intelligence on supported models; on older devices the app falls back to a guided, evidence-based reflection so journaling always works.
Do I need Apple Health?
No. Health is optional. If you connect it, MindLens shows how sleep, HRV, and exercise relate to your mood — all computed on-device. If you don't, every other feature still works.
What happens if I write something dark?
MindLens detects crisis-adjacent content on-device, suppresses the AI reflection, and surfaces real human support — the 988 Suicide & Crisis Lifeline and the Crisis Text Line — in a card you can act on immediately.
How much does it cost?
The free Lite tier gives you one entry a day forever. Pro is $9.99/mo or $79.99/yr with a 30-day free trial and unlocks unlimited entries, AI reflection, Health correlations, and the full toolkit. A $149.99 lifetime option is available for those who'd rather own it outright.
A calmer, more self-aware mind — that stays entirely yours.
