PillSeal vs a phone alarm
Plenty of people manage their medication with a repeating alarm in the Clock app. It is free, it already works, and it uses the same alarm mechanism PillSeal does. If you are doing that and it is working, you may not need an app at all.
Here is where it stops working.
The short version
A Clock alarm is excellent at making a noise at a time. It knows nothing about what the noise is for.
That is fine for one medication at one time a day. It degrades quickly once you have several medications, several times, or any rule more complicated than “every day”.
Where it breaks down
1. It cannot tell you what to take.
The alarm goes off. It says “Alarm”, or whatever you typed in the label. It does not know you take 500 mg of one thing and one tablet of another, or that one of them needs food, or what the pill looks like.
2. It does not know whether you took it.
You turn the alarm off. That is all the information that exists. An hour later, when you are not sure whether you actually took the dose, there is nothing to check. This is the failure people describe most often, and it is not a memory problem, it is a record problem.
3. It does not adapt.
Every schedule change means editing alarms by hand. A medication ending, a dose moving, a course of antibiotics for ten days: all manual. Miss one edit and the alarm is wrong, which is worse than no alarm.
Where they are the same
Worth being clear: the alarm itself is the same technology. PillSeal uses the same iOS alarm mechanism as the Clock app, which is exactly why it sounds through silent mode and Focus. We are not claiming a louder or more special alarm. We are claiming the alarm knows what it is for.
What PillSeal adds
| Phone alarm | PillSeal | |
|---|---|---|
| Sounds through silent and Focus | Yes | Yes |
| Knows which medication and dose | No | Yes |
| Comes back until you take it | No | Yes |
| Records that the dose happened | No | Yes |
| Handles several medications and times | Manually | Automatically |
| Warns you before you run out | No | Yes |
| Checks whether you have eaten first | No | Yes |
Our honest recommendation
If you take one medication, once a day, every day, and you have never lost track of whether you took it, a Clock alarm is genuinely sufficient. Use it and keep the money.
Consider PillSeal when you cross one of these lines: a second medication, a second time of day, a schedule that is not simply daily, or the first time you stand in the kitchen genuinely unsure whether you already took it.

Common questions
Do iPhone Clock alarms go off on silent?
Yes. Alarms set in the Clock app sound even when the ring switch is on silent and when Do Not Disturb or another Focus mode is on. PillSeal uses the same mechanism, so there is nothing louder or more special about its alarm.
Can I just use a phone alarm for my medication?
For one medication, once a day, every day, yes, and you should keep the money. It stops working once you have a second medication, a second time of day, a schedule that is not simply daily, or the first time you cannot remember whether you already took a dose.
Does a phone alarm know whether I took the dose?
No. Turning the alarm off is the only thing that gets recorded, and that happens whether or not the dose did. An hour later there is nothing to check, which is a record problem rather than a memory problem.
