The Deadlio card on a Companies House company page (example company).

On Companies House: open any company page and a Deadlio card appears under the company name, with both deadlines shown as ring charts that fill up as each deadline gets closer: green when there is plenty of time, amber within 30 days, red when overdue.
Penalty estimate: if the accounts are late, it shows the likely Companies House penalty if they were filed today, and what it would be if last year's accounts were late too.
Quick search: click the Deadlio Sense icon in your toolbar and type a company name or number.
Watchlist and reminders: choose Remind me and Chrome tells you before each deadline. Your watched companies are listed under Watchlist.
Strike-off checker and weekly deadline emails: one click from the card.

How to use it

Add it to Chrome from the Chrome Web Store. It works in Google Chrome on Windows, Mac and Chromebook, but not on phones.
Pin it: click the jigsaw icon at the top right of Chrome, then the pin next to Deadlio Sense, so the violet D stays in your toolbar.
Check a company on Companies House: open any company page. The Deadlio card appears under the company name, and on its Filing history and People tabs too.
Or search: click the D icon and type a company name or number, then pick the company.
Get reminders: choose Remind me of these deadlines on the card, or Remind me in the toolbar. You'll find it under Watchlist, where you can also remove it.

How reminders work

Deadlio checks your watched companies once a day while Chrome is open, starting a minute after Chrome opens. On the free plan you get a reminder 7 days before each deadline and another on the day it becomes overdue. Each reminder appears once. Click it to see the company on deadlio.co.uk.

Reminders are pop-up notifications from Chrome. If you don't see them:

Windows: go to Settings → System → Notifications and make sure Google Chrome is switched on. If Do not disturb or Focus is on, reminders go quietly to the notification centre instead.
Mac: go to System Settings → Notifications → Google Chrome and allow notifications.
Chrome closed? The check runs the next time you open Chrome.

Questions

Is it free?

Yes. The deadline card, penalty estimates, searches and reminders for one company are free and need no account.

Where does the information come from?

From the public register at Companies House, through deadlio.co.uk. Deadlio is not part of Companies House or GOV.UK. If a date looks wrong, check the company's page on Companies House.

Is the penalty figure exact?

No, it's an estimate based on the standard Companies House late filing penalties and assumes the accounts are filed today. The actual penalty depends on when they're filed and on the previous year. Check GOV.UK for the official rules, and see the Penalty Appeal Pack if there was a good reason for the delay.

Why didn't a reminder pop up?

Chrome needs to be open and allowed to show notifications. See How reminders work above. A company you've just added is checked again at the next daily check.

How do I remove it?

Right-click the Deadlio Sense icon in your toolbar and choose Remove from Chrome. This also deletes your watchlist and settings.

Running a practice?

Sense time capture records how each working day is spent on each client.
