FocusCurve shows you what your ADHD medication is doing, on an estimated timeline, in real time, personalized to you. APPLE WATCH See your estimated curves, log saved favorites from your wrist, and add FocusCurve to your watch face. Set up with your paired iPhone. REAL-TIME MEDICATION TIMELINES Every formulation releases differently, and FocusCurve models each one: - Immediate release (Ritalin IR, Adderall IR, dexamfetamine) - Biphasic bead release (Ritalin LA, Focalin XR, Adderall XR, Medikinet) - OROS extended release (Concerta and the Concerta XL family) - Prodrug conversion (Vyvanse / Elvanse) Log a dose and watch the estimated curve rise, peak, and fade, so you can plan deep work for the peak instead of fighting your brain through the dip. CAFFEINE ON THE SAME TIMELINE Caffeine is a stimulant too, so FocusCurve models coffee, tea, and energy drinks on the same timeline as your medication. See how an afternoon espresso stacks on your dose and shifts your sleep window, before you drink it. TONIGHT'S SLEEP, ESTIMATED FROM TODAY FocusCurve estimates when sleep becomes realistic tonight, based on the doses and caffeine you actually logged, not a generic bedtime rule. DOUBLE-DOSE AWARENESS "Did I already take it?" Your dose history is one glance away, with reminders and a live timeline, so the morning autopilot question always has an answer. CHECK-INS THAT BECOME PATTERNS Log symptoms, mood, and side effects in seconds. Every check-in lands on your curve, so over time you can see how what you feel lines up with where your dose is, and spot patterns worth a conversation. READY FOR YOUR NEXT APPOINTMENT Turn weeks of logs into a clean, visit-ready PDF summary of doses, patterns, and check-ins, so your prescriber sees data, not guesswork. THE PRACTICAL LAYER Medication inventory that knows when you're running low. Regimens and schedules for multi-dose days. Appointment prep, vitals, and Home Screen and Lock Screen widgets that keep today's curve in view. WHAT PEOPLE USE FOCUSCURVE FOR - Timing deep work to their medication peak - Deciding whether a 3 pm coffee is worth tonight's sleep - Answering "did I take my meds?" without opening the pill bottle - Understanding why some afternoons crash harder than others - Tracking a new medication or dose change with real data - Walking into appointments with a clear summary SUPPORTED MEDICATIONS Methylphenidate (Ritalin IR/LA, Concerta, Medikinet, Equasym XL, Xaggitin, Delmosart, Matoride, Xenidate and Rubifen Prolong), dexmethylphenidate (Focalin XR), amphetamine (Adderall IR/XR, Zenzedi, Amfexa, Attentin), lisdexamfetamine (Vyvanse, Elvanse), non-stimulants (atomoxetine / Strattera, guanfacine / Intuniv, Bupropion IR/SR/XL), regional generics, and caffeine in all its forms.

Verdict
The clearest difference is rating: CoreTell at 5.0 against FocusCurve's 4.0. CoreTell also leads on ads (none vs shown). FocusCurve's advantage is update cadence (every 10 days vs every 3 months) and ratings volume (6 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. CoreTell sells 2 in-app purchases, starting at $4.99 per month and FocusCurve sells 3 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.
CoreTell holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: FocusCurve has 6 ratings behind it against 1, so its average is the more settled of the two.
CoreTell ships an update every 3 months, FocusCurve every 10 days. The most recent releases landed on October 30, 2026 and November 5, 2026 respectively.
