FocusCurve visualizes your medication's estimated timeline — when it peaks, when it fades, and when you can actually fall asleep. Tracks caffeine too, because nobody else does.
Estimated timelines based on published models. Not medical advice.
Every feature exists because someone with ADHD actually needed it. No bloat. No gamification. The information you wish you had three prescriptions ago.
FocusCurve visualizes your estimated medication timeline — when it's building up, at its peak, and wearing off. Not a countdown timer. A real curve showing how your medication's effect changes throughout the day, personalized to you.
You already know your afternoon coffee affects your sleep. But how much? FocusCurve models caffeine alongside your ADHD medication on the same timeline. See how that 3 PM espresso shifts your sleep window — before you drink it.
FocusCurve estimates your earliest sleep window based on both your medication and caffeine levels dropping to sleep-ready levels. Not a generic "don't take meds after 2 PM" rule — an estimate based on your doses, your timing, and your metabolism.
Set your body weight, and FocusCurve adjusts the model to you. The onboarding questionnaire estimates your personal parameters. Fine-tune if you want to, or trust the defaults.
FocusCurve shows your last dose front and center with a persistent banner, and warns you if you try to log a second dose while the first is still active.
Ritalin IR, LA, Medikinet CR, Concerta, Adderall IR, XR, Vyvanse, and Elvanse — FocusCurve models each formulation the way it actually works. Regional brand names included.
Real screens, not mockups. What you see is what you get.
No account creation. No cloud sync. No data leaves your phone.
Tell us your weight, your medication, how long it usually lasts for you, and whether you smoke or take hormonal birth control. We estimate your personal parameters from your answers.
Tap once to log your medication or caffeine. FocusCurve remembers your usual dose and formulation. Quick-log from a notification with a single tap.
Watch your estimated medication timeline update in real time. See when it peaks, fades, and when your body will be ready for sleep.

No. FocusCurve is a visualization and educational tool. It uses published models to provide estimates of how your medication and caffeine levels change over time. It does not diagnose, treat, or provide specific medical recommendations.
FocusCurve supports methylphenidate, amphetamine, and caffeine timelines, including 35+ common brand names and formulations. Brand names vary by market, so choose the matching active ingredient and release type if your package uses another local name.
All on your device. Nothing is sent to a server. No cloud sync, no analytics on your health data, no third-party access. We don't know what medication you take. Your phone knows. We don't.
Because charging people with ADHD a recurring fee — knowing they might forget to cancel — is a bad look. FocusCurve is a one-time purchase. $3.99. All features. Forever.
Based on published research. Individual metabolism varies. The estimates are directionally useful but approximate. Use the personalization settings to fine-tune.
This feature is planned. FocusCurve will be able to generate reports showing your dose history, estimated medication timelines, and sleep predictions. You'll be able to share them via your phone's standard share sheet — email, message, AirDrop, or print as a PDF.
Download FocusCurve and see what your medication is doing — in real time, on an estimated timeline personalized to you. Track caffeine too. Know when you can sleep. Stop guessing.
