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.
Daily — same time, every day. The free built-in option comes first below, because for plenty of people it is genuinely the whole answer.
Daily is the easiest rhythm to set and the easiest to stop seeing: after a fortnight the alert is part of the furniture and gets cleared without being read.
Why this one slips: It needs no equipment and no place, which is why nothing in your day physically prompts it — the whole habit rests on the prompt.
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: a calm silent banner is the easiest thing on the phone to postpone, because postponing costs nothing today.
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 needs no equipment and no place, which is why nothing in your day physically prompts it — the whole habit rests on the prompt.
Starting, stopping and switching — the time-blindness shaped problems a silent banner is worst at solving. 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. Daily is the easiest rhythm to set and the easiest to stop seeing: after a fortnight the alert is part of the furniture and gets cleared without being read.

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.
