FocusCurve: ADHD Med Tracker

FocusCurve shows you what your ADHD medication is doing — on an estimated timeline, in real time, personalized to you. Most ADHD medication apps treat your dose like an on/off switch. FocusCurve uses established modeling to visualize how your medication builds up, peaks, and wears off throughout the day. See the actual curve — not a countdown timer. REAL-TIME MEDICATION TIMELINES Visualize your estimated methylphenidate or amphetamine activity over time. Each formulation is modeled with its specific release mechanism: - Ritalin IR: single-phase release - Ritalin LA / Medikinet CR: biphasic bead release - Concerta: OROS osmotic gradual release - Focalin XR: extended-release dexmethylphenidate (single enantiomer) - Adderall IR: immediate release - Adderall XR: two-phase beaded release - Vyvanse / Elvanse: gradual prodrug conversion CAFFEINE TRACKING — ON THE SAME TIMELINE FocusCurve is the only ADHD medication tracker that models caffeine alongside your stimulant medication. See how your afternoon coffee shifts your sleep window — before you drink it. SLEEP PREDICTION Know when both your medication and caffeine levels will drop to sleep-ready levels. Not a generic "don't take meds after 2 PM" rule — an estimate based on your actual doses, your timing, and your personal metabolism. DOUBLE-DOSE AWARENESS See your last dose front and center. If you try to log a second dose too soon, FocusCurve shows your current estimated medication level and warns you — so you never have to wonder "did I already take it?" PERSONALIZED TO YOUR METABOLISM A quick onboarding estimates your personal parameters: body weight, metabolism speed, hormonal factors, and caffeine sensitivity. Fine-tune manually or trust the defaults. Your curve. Your body. ALL DATA STAYS ON YOUR DEVICE No cloud. No accounts. No analytics. Crash reports are anonymous and contain no health data. Everything is stored locally on your iPhone. ONE-TIME PURCHASE All features included from day one. No subscription. No premium tier. No feature gating. No free trial that auto-renews. We chose this model because charging people with ADHD a recurring fee they might forget to cancel is not something we are willing to do.
