Recurring Todo: Why Task Apps Fail at Repetition (and the Interval Fix)

Every task app has a recurring todo feature. And almost all of them get it wrong.

They treat a recurring task like a calendar event: "repeat every Monday." That works for meetings. It fails for chores, because chores don't care about Mondays — they care about when you last did them.

The two kinds of repetition

Calendar-based: "Every Monday at 9am." Good for stand-ups, trash day, piano lessons.

Interval-based: "Every 30 days since I last did it." Good for changing filters, watering plants, cleaning gutters, washing bedding.

If your task app only supports the first kind, your recurring todos will drift. Skip the filter change for a week? The next reminder still fires on the original schedule — now wrong.

Why date-based recurring todos fail

Drift — do the task late, and the schedule stays anchored to the original date.
Guilt pile-up — missed tasks stack as overdue, so you ignore the app.
No memory — the app can't answer "when did I last do this?"

A todo that lives on a calendar is really an event. A recurring chore is a countdown.

The interval approach

An interval-based recurring todo resets every time you complete it:

You log "changed HVAC filter" today.
The app starts a 90-day countdown.
Day 90: one reminder. Done it? Countdown restarts.

No overdue pile-up. No drift. And you always know the last time you did each task — which is the question you actually ask yourself.

Best apps for interval-based recurring todos (2026)

hōki — purpose-built for interval repetition. Every task is "every N days/weeks/months," with a full last-done history and one-tap logging. iOS only. Download on the App Store.

Todoist — supports "every 30 days" (interval) vs "every day 30" (calendar) syntax, but the distinction confuses new users and the last-done log is buried.

Apple Reminders — repeat options exist but are calendar-anchored; no interval reset, no history view.

Which should you choose?

Tasks tied to dates (meetings, bills, events) → any task app works.
Tasks tied to last done (chores, maintenance, health habits) → interval-based app like hōki.

FAQ

What is a recurring todo?

A recurring todo is a task that repeats automatically on a schedule — either calendar-based ("every Monday") or interval-based ("every 30 days since last done").

Why does my recurring todo keep drifting?

Because your app reschedules from the original due date, not from when you actually completed the task. Switch to an interval-based app.

Does hōki handle both kinds of repetition?

hōki focuses on interval repetition — the kind most apps get wrong. For calendar events, use your calendar app.

Bottom line

If your recurring todos keep going overdue, the problem isn't you — it's the repetition model. Interval-based apps like hōki reset the countdown every time you finish a task, so the schedule always reflects reality.
