The hard part of taking medication on time isn't remembering that you take it. It's the eight o'clock dose on the morning your phone is face-down and muted, the antibiotic that has to land after a meal you ate two hours late, and the fourth prescription that turns a tidy list into a puzzle. Most pill reminder apps on the iPhone are a repeating alarm with a pill icon, and a repeating alarm loses to Silent mode every time.
Doz is built around the three places those apps break.
1. A silenced iPhone shouldn't mean a missed dose
A standard iOS notification is suppressed by Silent mode and by every Focus you have set up. That is correct behaviour for a marketing push and the wrong behaviour for medication.
Doz supports Critical Alerts — the same iOS capability used for health and safety notifications. A medication reminder can sound even when your phone is on Silent or inside a Focus, because that is the one notification you asked not to miss. Everything else Doz sends stays quiet.
Critical Alerts is a separate iOS permission that has to be granted explicitly, so it is worth checking after install. The support page walks through it.
2. "After dinner" is not a clock time
Plenty of prescriptions are written relative to food: with a meal, thirty minutes after dinner, before breakfast. An app that only stores 8:00 PM will nag you while you're still cooking, and on the nights you eat late the instruction on the label quietly stops being followed.
In Doz, a dose tied to a meal follows your real mealtimes. Move dinner and the dose that belongs after dinner moves with it. The same logic covers the other cases a fixed alarm handles badly: doses shift when you cross time zones, and cycles such as 21 days on and 7 days off run without you tracking the calendar yourself.
3. Four prescriptions shouldn't read as fourteen pills
Once you're on more than one course of treatment, a flat list stops matching how you actually think. You don't remember "amoxicillin, ibuprofen, losartan, amlodipine" — you remember the sinus infection and the blood pressure medication.
Doz groups every pill under the prescription it came from. One prescription becomes one card, carrying the medications inside it, who prescribed it, and how long the course runs. You add the prescription once, in one flow, and every reminder is generated from it. Refill warnings arrive while pills are still in the bottle rather than after you've run out, and the next dose sits on your Lock Screen.
What it costs, and what it doesn't take from you
Doz is a free download. An optional Doz Pro subscription is available as an Apple in-app purchase — see the FAQ for how billing and cancellation work.
There is no account to create and no ads. Your prescriptions and schedules live on your device; the app works fully offline, and if you turn on sync it goes through your own iCloud using Apple's private CloudKit database, which the developer cannot read. The privacy policy states exactly what is and isn't collected.
What Doz is not
It's a reminder and organisation tool, not a medical device and not medical advice. It won't tell you what to take or suggest a dose — enter what your doctor prescribed, and take questions about your treatment to your doctor or pharmacist.
It's also iPhone-only for now. Critical Alerts and private CloudKit sync are Apple frameworks, so there is no Android version.
