Methylphenidate & AmphetamineCaffeine Stacking

Medication and caffeine on one unified timeline

Log coffee, tea, or booster doses beside your primary medication. FocusCurve charts the pharmacokinetic overlap in real time so you can anticipate the afternoon dip instead of wondering why your focus suddenly shifted.

Formulation-Aware PK

Accounts for enteric-coated beads, laser-drilled osmotic pumps (OROS), and prodrug cleavage rates.

Caffeine Stacking

Tracks coffee, tea, and energy drinks on the same curve so you see total CNS stimulation in real time.

Pill Inventory & Refills

Tracks remaining tablet count and alerts you before 30-day controlled substance prescriptions run empty.

On-Device Privacy

Your medication history and symptom notes stay encrypted locally on your device. No cloud sync.

Common questions

Is FocusCurve a medical device?

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.

Can I try the pharmacokinetic curve without installing the app?

Yes! You can explore our free interactive Bedtime & Stimulant Clearance Calculator on this website to test how different medications, release mechanisms, and caffeine intakes are modeled throughout the day.

Which medications does FocusCurve support?

FocusCurve supports 50+ medication names and formulations across methylphenidate, amphetamine, selected non-stimulants, and caffeine. Brand names vary by market, so choose the matching active ingredient and release type if your package uses another local name.

How does FocusCurve track pill inventory and prescription refills?

FocusCurve lets you log pack sizes and remaining pill counts. It automatically decrements your inventory with each logged dose and alerts you days in advance when it is time to contact your prescriber for a controlled substance refill.

Where is my data stored?

Medication, caffeine, symptom, mood, sleep, note, and inventory records stay in the app on your device. Limited non-health information may be processed for App Store purchases, optional analytics, crash diagnostics, or support. The Privacy Policy lists every provider and choice.

Which purchase options are available?

FocusCurve and the Apple purchase sheet show the exact options, localized price, billing period, renewal terms, and trial eligibility before confirmation. Options may include monthly or annual Plus subscriptions and a Lifetime purchase. Eligible prior paid-version customers keep Plus access.

How accurate are the estimates?

FocusCurve uses published models, but individual response varies. Its timelines are approximate educational estimates, not measurements or guarantees. Compare them with your own records and discuss medical questions with your clinician.

Can I share my data with my clinician?

Yes. FocusCurve can create a clinician-ready PDF from records you choose. Review it first, then share it using the standard iOS share sheet.

Your day has a pattern. Make it legible.

Keep your doses, caffeine, symptoms, sleep, and mood together, then compare them with an estimated timeline built from the information you record.
