A tracker, not an advisor

This is a logbook. You write down what your doctor or pharmacist prescribed; the tool helps you remember to take it on time, see how consistent you've actually been, and bring a clean list to your next appointment.

We deliberately don't check drug interactions, suggest doses, flag symptoms, or interpret bloodwork — those are clinical questions. They belong to your prescriber and your pharmacist, who know your full history. Treat this tool the same way you'd treat a paper pill organizer: useful, dumb, yours.

Who this is for

• People on chronic medication — blood pressure, cholesterol, diabetes, thyroid, mental-health, transplant, post-cardiac. Adherence is the single biggest predictor of outcomes on most of these meds, and the most under-tracked.
• Anyone on a short antibiotic or steroid course. Finishing the course matters; missing doses creates resistance. The 7-day grid is built for exactly this.
• Caregivers managing a parent, partner, or child's meds. The multi-profile model means "Mom's morning meds" lives next to "my morning meds" with no mental switching.
• People who travel across time zones. Long-haul travel routinely breaks medication schedules — we let you shift the schedule for a trip without breaking the spacing math.

What the tool does

A clear list for today

Every scheduled dose for today, ordered by time, each row colored by the medicine and tagged by time-of-day (☀ morning, ☕ noon, 🌇 evening, 🌙 night) and with-food / empty-stomach flag. Tap once → marked taken with timestamp. The timestamp solves the single most common real-world failure: "wait, did I already take it?"

Color-coded medicines

Every medicine gets a user-chosen color and a shape icon (tablet · oval · capsule · liquid · injection · drops · inhaler). For someone on eight pills, scanning rows by color is dramatically faster than reading names.

Frequencies that match real prescriptions

• Daily, every other day, specific days of the week.
• Every X hours (with start time anchored — e.g. "every 8 hours from 7 AM").
• PRN / as-needed (logged when taken, no schedule slot).
• Short course with an end date (the row disappears when finished — finally).

Honest adherence numbers

• Current streak (consecutive days where every scheduled dose was taken).
• 30-day adherence percentage per medicine — the number your doctor actually wants to see. 80%+ is the threshold most clinical guidelines use to consider a patient "adherent."
• Side-by-side calendar grid (last 14 days) showing missed vs. taken vs. taken-late.

Refill prediction

Enter your remaining pill count when you start the bottle; the tool warns you when stock will run out before your next refill date.

Doctor-visit PDF

One-click export: every medication you currently take, with dose, frequency, prescriber (optional), and adherence percentage. Bring this to your next appointment instead of trying to remember on the spot.

Printable fridge sheet

A 7-day grid you can print and stick on the fridge. Useful for caregivers, for grandparents who don't use phones, and for the partner who's covering when you're away.

Privacy — actually

Medication data is among the most sensitive data you have. The tool stores everything in your browser's local storage. No account is required, no data is uploaded, the team running Toolenza never sees what you take. Pro users who want cross-device sync or push notifications opt in explicitly; even then the medication name and dose stay encrypted in transit. (Why your medication app shouldn't have your email address — full reasoning.)

The science of medication adherence (briefly)

• About 50% of people on chronic medication take it as prescribed — that's the long-running WHO estimate, and recent studies put the real number even lower for some categories (Brown & Bussell, 2011).
• The single largest cause of non-adherence isn't cost or side effects — it's simple forgetting, especially in polypharmacy (4+ daily meds), where the mental load compounds.
• Visible cues (a pill organizer, a checklist, a colored marker on a calendar) are the most evidence-supported low-cost intervention. The behavioral mechanism is straightforward: when the cue is in your environment instead of your memory, you don't have to remember to remember.
• Streak-style trackers add a small but meaningful motivational nudge (the same loss-aversion that makes Duolingo work), without becoming a guilt machine if you miss a day.

What this tracker won't do (and why)

• It won't check drug interactions. That requires a clinically validated database (Lexicomp, Micromedex, First Databank) and would put Toolenza into FDA / EU MDR medical-device territory. Ask your pharmacist — every modern pharmacy system checks interactions when filling.
• It won't recommend or change doses. Even "you might be taking too much" is a clinical judgment. If something feels wrong, call your prescriber.
• It won't diagnose or track symptoms. Symptom tracking that hints at a diagnosis is a different regulatory category and a different tool. We keep this one a clean logbook.
• It won't share your data with your doctor automatically. Use the PDF export — print it, hand it over, you stay in control of the disclosure.
