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: Nothing visibly changes when it is overdue, so the only thing tracking it is a note you wrote months ago and cannot now find.
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: the alert arrives when there is no spare filter in the house, so it becomes a shopping task and then nothing.
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.
Nothing visibly changes when it is overdue, so the only thing tracking it is a note you wrote months ago and cannot now find.
Weekly rhythms and one-off risks around the house, from bin night to the oven you walked away from. 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.
