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 know your answer immediately and still do not send it, and eventually the host has to guess on your behalf.
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: replying takes fifteen seconds, which is exactly the size of task a silent banner is best at deferring.
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 know your answer immediately and still do not send it, and eventually the host has to guess on your behalf.
Deadlines, renewals and paperwork that nobody else is going to chase you about. 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.
