A checklist on every Safari new tab, from the App Store. Write it on the Mac in the morning, tick it off in Safari on the iPhone through the day — the same list, no Reminders app in between.
The Safari-specific flow, start to finish.
A short tour of the widget. Already sold? Skip ahead.
Safari is the one browser whose new tab genuinely follows you from desk to pocket, and Apple only uses that for Favorites and Reading List. The Todo widget uses it for the list. The Start Page HQ app on the App Store installs the Safari extension on macOS 12.4 and later and on iOS and iPadOS 15 and later, so the list you write on the Mac is on the phone the next time Safari opens a tab — no Reminders, no Notes, no third-party app to keep in sync, and the tasks live on your account rather than in iCloud, which also means they reach Chrome or Firefox at work if you sign in there.
On the Mac, the Safari extension shares your sign-in with the Start Page HQ app through the Keychain, which is how an in-app purchase made in the iOS app lands on the same account as the list. And since the tasks are stored on the account, clearing Safari website data or reinstalling the app does not touch them — sign in and the list is back. If you ever want the Start Page again, untick the extension in Safari settings; the list keeps waiting on the account.

Pair the Todo widget with these. One install gets you all of them.

A board for work with stages, next to the flat list for everything else.
For the daily things that should never be retyped into a todo list.

Twenty-five minutes on the top task before looking at the rest.

The paragraph behind a one-line task, in a widget beside it.

A scratchpad for what is not a task yet.

The favorites grid from Safari's Start Page, kept next to the list.
The Todo widget is one of 50+ in Start Page HQ. Tasks, notes, RSS, AI tools, dev utilities — the same install gives you all of them. Start free with 8 widgets on a page, or lift every limit at $3.99/month, $25/year, or $49 lifetime.
Yes. Install the same App Store app on the phone, enable it under Settings → Safari → Extensions, and sign in. Safari's new tab shows the dashboard and the same list, and a task ticked off on the phone is ticked off on the Mac.
No — through your Start Page HQ account. That is why it works between Safari on a Mac and Safari on an iPhone without any iCloud setting, and also reaches Chrome, Firefox, Edge, and the hosted web app if you use those elsewhere.
On the Mac: open the app once, then tick Start Page HQ under Safari → Settings → Extensions and allow its permissions. On iOS: Settings app → Safari → Extensions, switch it on, set to Allow. Open a new tab and the dashboard is there.
No. Tasks are stored on your account, not in Safari. Clearing website data may sign the dashboard out; sign back in and the list is unchanged.
