Everything on one screen: how often this usually needs to happen, the free way to set it on the iPhone you already own, and what changes if a phone call does it instead.
Every few months — every three to six months. The free built-in option comes first below, because for plenty of people it is genuinely the whole answer.
At this spacing you have completely forgotten the last one by the time the next is due, and an alert set months ago arrives with none of the context that made it matter.
Why this one slips: It is booked at the end of the last visit, six months out, on a card that goes straight into a drawer.
Two alerts on a dated event is genuinely the right free tool for a deadline, and it costs nothing. Its weakness is the same as every notification: both alerts are silent banners you can clear without doing anything. If the timing is the hard part, an iPhone Clock alarm is stronger — iOS exempts alarms from the silent switch and from Do Not Disturb.
A silent banner still loses here: a check-up has no urgency until the day it does, which makes it the easiest thing to postpone by a year.
With ReminderCall your phone rings like a normal incoming call — a real call over the phone network, not a banner and not an in-app alarm. You answer, and a voice reads the reminder out loud in the words you wrote. Answering is an action, which is harder to do absent-mindedly than clearing a notification.
To be precise about it: a call follows your ring settings rather than your notification settings. On hard mute it vibrates and takes over your screen instead of ringing out loud, unless you save the number as a contact with Emergency Bypass switched on yourself.
It is booked at the end of the last visit, six months out, on a card that goes straight into a drawer.
Dates set by somebody else, where the reminder you actually need is the leaving time — not the appointment. The failure is almost never that you did not know — it is that the prompt arrived at a moment when acknowledging it was easier than acting on it. At this spacing you have completely forgotten the last one by the time the next is due, and an alert set months ago arrives with none of the context that made it matter.

The other free move, and often the more effective one: anchor it to something you already do without thinking — after the kettle goes on, before you lock the front door, as you sit down at your desk. A reminder attached to an existing habit needs far less from your phone. Try both for a fortnight before you pay anybody for this.
