Tracking renewals: calendar, to-do app or tracker?
Google Calendar, Apple Calendar, Due, Todoist or a renewal tracker like DueOwl — what each does well for MOT, insurance and passport dates, honestly compared.
On this page
Every family tracks renewals with something — a calendar, a to-do app, a drawer, a memory. The honest answer to “which tool?” depends on how many dates you juggle and how many people need to see them. Here’s what each option actually does well, including where the app we make isn’t necessary.
The three approaches, compared
| Shared calendar (Google / Apple) | Reminder / to-do app (Due, Todoist) | Renewal tracker (DueOwl) | |
|---|---|---|---|
| Cost | Free | Free–£ | Free (Pro for some features) |
| Holds the renewal date | ✔ | ✔ | ✔ |
| Keeps nagging until done | Alert can be dismissed | ✔ Due’s auto-snooze excels | ✔ |
| Different lead times per type | Manual per event | Manual per task | Built in (passport 6 months, insurance 4 weeks…) |
| Policy document attached | ✘ | ✘ | ✔ scanned or shared in |
| Last year’s cost, provider, reference | ✘ | ✘ | ✔ |
| Both partners see everything, live | ✔ if you share the calendar | Mostly single-user | ✔ by design |
| Who’s responsible | ✘ | Assignees in paid tiers | ✔ |
| Where the data lives | Google’s / Apple’s cloud | The app company’s cloud | Your own iCloud (documents never reach the company) |
| Setup effort | Type every event + alert | Type every task | Scan the document; dates read on-device |
When a calendar is genuinely enough
A shared calendar is the right answer more often than an app maker would like to admit: few renewals (say a car, home insurance and two passports), one organised adult, alerts set 30–60 days out, and the discipline to add every new contract the day it’s signed. If that’s your household, add the dates from our UK renewal calendar with the lead times it lists — or generate them in one go with the free renewal reminder .ics tool — and you’re done.
The calendar’s real weaknesses show at the moment of action: the alert fires, and now you need the policy document, last year’s premium and the excess to compare quotes — none of which live in the calendar. And a dismissed alert is gone; nobody chases you.
When a reminder or to-do app fits
Due (iPhone) is the best pure nag we know: it re-alerts every few minutes until you mark a thing done, which is perfect for “tax the car today”. Todoist handles recurring chores across platforms and shares projects. If your problem is acting on dates you already know, they’re strong — and cheaper than switching systems. Their limits are the same as the calendar’s (no documents, no costs) plus one more: they’re built around one person’s task list, not a household’s shared picture.
When a tracker earns its place
The pattern we built DueOwl for shows up in the research on family mental load: dates scattered across inboxes, documents in a drawer, and the whole picture living in one partner’s head — so a missed MOT is discovered by the other partner at the worst moment. A renewal tracker keeps the date, the document, the cost and the owner together, applies the right lead time per type, and shows both partners the same list live. In DueOwl’s case the documents also stay in your own iCloud and never reach us.
Setting up whichever you choose
- 1List every renewal firstThe one-hour audit finds them all — insurance, MOT, tax, energy, broadband, passports, GHIC, TV Licence.
- 2Use the right lead time, not one defaultPassports and mortgage deals need ~6 months; insurance, MOT and energy 4–7 weeks; a same-week alert is a bill, not a decision.
- 3Make it visible to both partnersWhatever the tool: if only one of you can see it, the household still runs on one point of failure.
- 4Attach the paperwork where you canThe renewal decision needs last year’s price and the policy terms. If your tool can’t hold them, agree one folder where they live.
In short
A shared calendar with long alerts is free and enough for simple households. Due or Todoist improve the nagging. A renewal tracker like DueOwl is for the household that also wants the documents, costs and responsibility attached — visible to both partners, stored in their own iCloud. Start free with the one-hour renewal audit and the .ics generator; upgrade to a tracker only if the gap is real.
Frequently asked questions
Isn't a shared Google or Apple calendar enough?
For a couple who already share a calendar and set 30–60 day alerts, often yes — for the dates. What a calendar can't do: hold the policy document, remember what you paid last year, tell you who's dealing with it, or apply different lead times per renewal type (passports need 6 months' warning, insurance 4 weeks). Every renewal also needs entering by hand with the right alert.
What about reminder apps like Due, or to-do apps like Todoist?
Due is excellent at nagging — its auto-snooze keeps re-alerting until you act, which beats a calendar alert you can dismiss. Todoist handles recurring tasks well. Both are single-person tools at heart, and neither stores the document or the cost — so at renewal time you still go hunting for the policy PDF and last year's price.
What does a renewal tracker add?
The context around the date: the document itself (scanned or shared in), the provider and cost, who's responsible, and reminders sized to the renewal type. DueOwl adds two things specific to families: both partners see the same list live, and the data stays in your own iCloud rather than on a company's server.
Can I use a calendar AND a tracker together?
Yes — that's the setup we'd recommend. Keep the family calendar for events and lifts; let the tracker own renewals and push the dates into the calendar. DueOwl has a one-way Apple Calendar sync for exactly this, and our free .ics generator does a lighter version for any calendar app.
Which should a typical family choose?
If your renewals are few and one of you reliably manages them: a shared calendar with long alerts is genuinely fine, and costs nothing. If renewals have been missed, documents are scattered, or one partner holds the whole picture: a tracker earns its place. Try the free route first — our renewal calendar tool takes two minutes — and upgrade only if it isn't enough.
