How it works

Three steps, none of them typing.

Set it up once. After that it only speaks up when you're actually going to be late.

  1. It finds your meeting

    Reads the next event on your calendar, including where it is and who's invited. Pick which calendars it can see.

  2. It tracks your ETA

    GPS and on-device smoothing keep a live estimate of when you'll arrive, even when the app is in the background.

  3. You send, they know

    If you'll miss the start, a countdown appears with the message ready. Tap send, or say "send" out loud.

Built for the road

Hands on the wheel, eyes up.

Everything that matters is a glance or a word away.

Voice confirm

Hear your ETA read aloud and reply "send" or "cancel". No screen touching.

CarPlay and Apple Watch

A glanceable countdown on the dashboard and on your wrist.

On my way, proactively

Prefer to get ahead of it? Send an "on my way" message before you're even late.

Arrival check-in

Optionally let people know the moment you've arrived, so nobody's wondering.

Smart ETA

An estimate you can trust.

A Kalman filter smooths out GPS noise and gives a confidence range, not just a single number. Pro adds live traffic from our server, so rush hour doesn't catch you out.

You're always the one who hits send. The app opens your own messaging app with the message ready. It never sends anything on its own, and it doesn't ask for SMS permission.

Privacy

Your day stays yours.

Calendar, contacts and location are processed on your device. Message text and recipients never touch our servers. No ads, no selling data, ever. Read the privacy policy for the details.

Questions

Good to know.

Do I need the internet for it to work?

No. GPS works without a data connection, and the message goes out as a normal text over cellular. Live traffic (Pro) and email do need a connection.

Will it text people without asking me?

Never. It prepares the message and you confirm, by tapping or by voice. Nothing is sent otherwise.

Does it work when the app is in the background?

Yes. Android checks continuously. On iPhone, iOS decides how often background checks run, so it's best-effort when the app is closed.

Which calendars does it work with?

Any calendar on your phone: Apple, Outlook, or anywhere else your calendar app syncs. You choose which ones it can read.

How do I cancel?

Manage or cancel any time in your App Store subscription settings. More answers are on the support page.

Stop apologizing after the fact.
