A mood tracker built by a doctoral-level clinician, with input from fellow clinical psychologists and neuropsychologists, using the actual clinical screening instruments your therapist uses: PHQ-9, GAD-7, WHO-5, DERS-16, SCS-SF, C-SSRS, ASQ, and STIPO-R. No AI therapy advice. No gamification. No social feed. No ads. Your data stays on your phone. Safety features are always free. Forever. No paywall on crisis resources, the safety plan, or the 988 Lifeline. — TRAUMA-INFORMED BY DESIGN — Built around the psychoanalytic concept of the "observing ego": the part of you that can step back and notice your own mental processes. The app is a mirror, not a therapist. It helps you see yourself clearly and bring that clarity to your own work, or to a clinician. — WHAT YOU CAN DO — Track moods with the precision your therapist would recognize. An age-adaptive picker (ages 7 through adult) draws from a 100+ emotion vocabulary mapped to validated affect models. Take the clinical screenings your therapist uses, scored to published thresholds. PHQ-9 for depression. GAD-7 for anxiety. WHO-5 for wellbeing. ASQ and C-SSRS for safety. STIPO-R for personality organization (uncommon outside research settings). See patterns over time. Mood correlations with sleep, exercise, medications, and habits. Year in Pixels view. Longitudinal assessment trends. Every correlation needs at least 7 data points and a moderate effect size before it surfaces. Quality over noise. Log defense mechanisms (Vaillant's three-tier hierarchy). Record dreams with psychodynamic framing. Practice mentalizing exercises drawn from MBT. Map body sensations to feelings. — PRIVACY BY DESIGN — No accounts. No servers. No ads. No analytics. No third parties. Your data syncs through your own iCloud, encrypted end-to-end. We cannot see your entries, your moods, or your reports. We do not want to. — SAFETY ALWAYS FREE — The safety plan, crisis resources, 988 Suicide & Crisis Lifeline, and gentle check-ins when the app detects elevated risk are free forever. Mood check-ins and journal entries are unlimited and free. Premium covers the deeper features: longer insight ranges, Year in Pixels, the Mood Calendar, weekly reports, Apple Health insights, medication effects, and data export, plus more room for habits, assessments, and medications. Safety never goes behind a paywall. — BUILT BY — Casey Simon, Psy.D. (Doctor of Clinical Psychology), MFT (Marriage and Family Therapist), with input from fellow clinical psychologists and neuropsychologists. Designed for honest self-reflection, not performance. A tool meant to be shared with a clinician when you choose to. — PRICING — Free to download. 7-day free trial of Premium. Then $4.99 per month or $44.99 per year. Safety features stay free regardless of subscription. Cancel anytime in App Store settings.
