Calibrate

Your first 90 days after an adult ADHD diagnosis are some of the hardest. The script is in your hand, the side effects are real, and your follow-up appointment is six weeks away. Calibrate is the 90-day symptom journal built for that window — so you walk into your prescriber's office with evidence instead of "I think it might be working? Sometimes?" WHAT CALIBRATE DOES • Daily medication log in 60 seconds — dose, time, focus 1-5, energy 1-5, side-effect tags • Calibration Arc — your 90 days mapped to the three phases of ADHD titration: Initiation (Days 1-7), Adjustment (8-45), Maintenance (46-90) • Phase transition modals at Day 8 and Day 46 — "what to expect" copy that normalizes what you're experiencing • "Today I Noticed" tags — 1-tap chips (side effect, win, question, trigger) plus optional notes up to 280 characters • Weekly Clinician PDF — auto-generated every Friday once you have at least 4 logged days that week. Dose log table, focus and energy sparkline, your own tagged highlights, prepared questions for your appointment • Day 90 Continuation — at Day 90 you choose to continue another 90 days, restart for a new medication, or archive your journey WHO IT'S FOR Adult women newly diagnosed with ADHD, prescribed your first stimulant — Vyvanse, Adderall, Ritalin, Concerta. You're working full-time. You've been on the waitlist for a year. The diagnosis is real but the day-to-day is overwhelming. Calibrate is your structured companion for the first chapter. WHY THIS, NOT A GENERIC TRACKER iPhone Notes works until your appointment. Then you're scrolling through fragmented scribbles, embarrassed to show your psychiatrist what you actually wrote. Generic chronic-illness trackers don't speak ADHD. Habit-builder apps don't know what titration means. Calibrate is built specifically for the 90-day post-diagnosis window — the only moment where this evidence matters most. WHAT YOUR PRESCRIBER SEES A clean one-page PDF: dose table for the week, focus and energy trend chart, side-effect summary, your tagged observations as quoted highlights, and prepared questions ("Side-effect chart shows X — should we adjust dose timing?"). Prescriber-ready, no interpretation required. NOT A MEDICAL DEVICE Calibrate is a personal symptom journal for your conversation with your prescriber. It does not diagnose, prescribe, dose-adjust, or replace medical advice. All clinical decisions belong to you and your doctor. PRIVACY Your medication log is stored locally on your device. We do not collect, share, or sell your health data. You export PDFs only when you choose to. CALIBRATE PREMIUM First 7 days (your full Initiation phase) are free. Continue your full 90-day journey with Premium: • $9.99/month • $49.99/year (save 58%) Includes unlimited weekly clinician PDFs, full Adjustment + Maintenance phases, and Day 90 continuation.
