Medication reminders that work on silent mode
A normal push notification obeys your ringer switch, so it stays silent exactly when you needed it loudest. Medifix schedules exact AlarmManager alarms on Android and uses critical alerts on iOS — both ring like an alarm clock regardless of the sound setting.
The problem: reminders disappear into silent mode
Most reminder apps are built on ordinary push notifications. That works fine while the ringer is on, but the moment the phone goes to silent or Do Not Disturb, a standard notification behaves like every other one: it appears briefly, makes no sound, and is muted by the operating system without further ceremony. For a chat message that is exactly right. For a dose you actually have to take, it is not enough.
This hits hardest for people who keep their phone silent for good reasons — overnight, in an office, in a lecture, in a cinema — and who therefore cannot rely on an app that respects that setting. With medication that has a narrow window, such as cardiovascular drugs or a course of antibiotics, a missed reminder is more than an annoyance.
The fix: exact alarms and critical alerts
Medifix does not treat a dose reminder as a notification. It treats it as an alarm. On Android it schedules exact AlarmManager alarms — the same system facility a clock app uses to go off reliably at a set time, regardless of silent mode, battery saver or Do Not Disturb. On iOS it uses critical alerts, a notification class Apple grants case by case for safety-relevant reminders, which deliberately bypasses the mute switch and Focus modes. Apple approved that entitlement for Medifix in July 2026.
The difference is not in how the reminder looks, but in what the operating system is told it is. Medifix requests the necessary permission during setup and then schedules the alarm so the OS treats it like a wake-up tone instead of quietly suppressing it. That also holds on devices from manufacturers like Samsung, Xiaomi and Huawei, which are known for aggressive battery management that likes to kill background work.
Who this matters most for
The problem is sharpest for people who have little control over their phone's volume: shift workers, students in exams, anyone in back-to-back meetings, or simply at night when the ringer stays off on purpose. In caregiving situations, or with chronic conditions that involve several doses a day, missed reminders add up quickly into a real gap in treatment.
From Android 12 onwards the system additionally requires an explicit permission for exact alarms, a response to apps abusing the feature. Medifix requests it once during setup and explains what it is for. Without it, reminders would arrive late or not at all — which is precisely what happens with most other apps.
What that looks like in practice
