Your day at a glance

A day is a circle. Arc lays it out.

Midnight sits at the top and time runs clockwise. Everything you need to read your day is arranged around one ring, so there's nothing to scroll through and nothing to dig for.

Your routine

Your everyday rhythm, like sleep, work, exercise and downtime, shown as soft coloured arcs. Set it once and it's there every day.

Your calendar

The events already on your phone, laid out around the outside of your day. Add or change one in Arc and your calendar updates too.

The weather

See the forecast right beside your plans, so you know what to expect before you head out. Use your location or pick any city.

Home-screen widget

Your whole day, right on your home screen. It keeps itself up to date, even overnight, so a single glance is all it takes.

Your routine

Design the shape of a good day.

Block out sleep, focus time, a workout, winding down. Each one gets its own colour, so your whole week is easy to read at a glance. No lists, no times to squint at.

  • Colour-coded arcs for sleep, work, exercise and downtime
  • Different rhythms for weekdays and weekends
  • Late nights stay with the day they belong to

How Arc works

No sign-up and no fuss. Open it and your day is already on the dial.

1

Sketch your routine

Add the things that repeat, like sleep, work, the gym and downtime. Pick a colour and the times, and Arc fills in your day.

2

Connect your calendar

Say yes to calendar access and your events show up right away. Pop the widget on your home screen for the day ahead at a glance.

3

Read your day at a glance

A moving hand shows the time now, with the weather alongside. One look tells you what's next and how long you've got, without even unlocking your phone.

Private by design

Your day stays yours.

Most planners send your calendar off to a company's servers. Arc doesn't. Your routine, your settings and your calendar all stay on your phone, where they belong. There's nothing sitting online to be leaked or handed over.

Only the weather goes outThe one thing Arc ever sends out is a rough location to fetch your forecast. That's it.

Good to know

Questions, answered

Does Arc send my calendar anywhere?

No. Arc reads the calendar that's already on your phone, and any events you add go straight back to it. Your calendar never gets sent to us or anyone else.

Do I need an account?

Never. There's no sign-up and no login. Just open the app and start blocking out your day. Everything you add is saved right on your phone.

What does the weather feature need?

To show your forecast, Arc needs either your location or a city you type in. That's the only thing it ever sends out, and it's used solely to look up the weather. You can skip it completely.

Does the widget keep working when the app is closed?

Yes. The home-screen widget keeps itself up to date and stays right even past midnight, so you always get the current day at a glance, whether or not you've opened the app.

Which phones does it work on?

Arc works on both iPhone and Android, with a home-screen widget on each.

Start reading your day differently.

Arc turns a long list of times into one calm circle. No account, no cloud, just your day at a glance.
