Remind me within

About a block. Good for a store you'll walk or drive into.

Alerts

On iPhone, checks where you are only while it’s open on screen. That’s a limit Apple puts on every web app, not a bug. Keep it open on the way and it alerts you the moment you arrive.

Places being watched0

Tip: for a drive, turn on Keep screen on, or set a longer Auto-Lock in Settings › Display & Brightness.

How it works

Save a reminder at a place. When you get there with open, it tells you right away.

Set one up

Tap +

Write what you need to do, like “Pick up challah.”

Pick the place

Search a store or address, or tap the map to drop the pin right where you want it.

Choose how close

The radius is how near you need to be. 250 m works for most stores. Go bigger for a whole mall or campus.

Options

Once or every visit

Once is for a one-off errand. Every visit reminds you each time you arrive, like “grab the mail at the office.”

Only between certain hours

Add a time window and it stays quiet outside it. Arrive at 11 PM with a 9–5 window and nothing goes off.

Start date

Set it for later and it waits under Upcoming until that day comes.

When you arrive

You get an alert

A card pops up with a chime. Tap Mark done, or Later. If notifications are on, a banner shows too.

In the list

Swipe right to finish

Or tap the circle. It moves to Done, with Undo if you slip.

Swipe left to delete

Tap a reminder to change anything about it.

Pause

Inside a reminder, turn it off for now without losing it. Turn it back on any time.

Good to know

Keep Derman open on the way

iPhone doesn’t let web apps check location in the background, so Derman watches while it’s on screen. The Watching badge up top means it’s checking.

Add it to your Home Screen

In Safari tap Share, then Add to Home Screen. It opens full screen and can show notifications.

Your reminders stay on your phone.
