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.
One-off — a single date and time. The free built-in option comes first below, because for plenty of people it is genuinely the whole answer.
One-off reminders carry the most risk per alert: there is no second chance next week and no habit to catch you if the single notification lands at a bad moment.
Why this one slips: You leave meaning to book it, the queue on the phone is long, and the follow-up quietly never gets made at all.
This is free, already on your phone, and for a lot of people it is genuinely enough — try it for a fortnight before paying anyone, including us. Its limit is that it ends in a notification: it is not exempt from Do Not Disturb the way a Clock alarm is, and a banner can be cleared without being read. If the timing is the hard part, set a repeating Clock alarm instead — iOS lets alarms sound even on a muted phone.
A silent banner still loses here: booking needs a call during opening hours, and the alert never seems to arrive during opening hours.
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.
You leave meaning to book it, the queue on the phone is long, and the follow-up quietly never gets made at all.
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. One-off reminders carry the most risk per alert: there is no second chance next week and no habit to catch you if the single notification lands at a bad moment.

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.
