The devices
You shouldn't have to choose between style and safety.
Two ways to wear it. The same alert technology, built from the inside out. One app. One subscription.
Wrist$79The Compass Band
Warm metal tones. Monitors bio-signals and activity from your wrist.
A slim alert bracelet in warm metal tones that monitors bio-signals and activity, then quietly notifies your trusted contacts when something feels off. Pairs with the Open Compass companion app. General-wellness alert device, no diagnostic claims. One subscription covers the Band and the Pendant if you own both.
Collarbone$89The Compass Pendant
The same alert electronics as the Band, housed in a pendant worn at the collarbone. Designed for people who want protection without a wrist device. Styled as jewelry, not medical equipment. Works on the same Open Compass app account and the same $7/month subscription as the Band.
One $7/month subscription covers both devices if you own both.
Three steps. Then it runs on its own.
No complicated setup. No constant attention. You wear it, the app works, and the people who matter most are covered.
Wear the device
Put on the Band or the Pendant. Both are designed to disappear into your day — warm metal tones, jewelry weight, nothing clinical.
The app listens quietly
Open Compass monitors bio-signals and activity in the background. No screens to check, no alarms to dismiss. It runs without asking anything of you.
Your people, alerted instantly
When something feels off, the app notifies your trusted contacts right away. They know. You don't have to manage the moment alone.
Open Compass is a general-wellness alert device. It does not diagnose, treat, or monitor medical conditions.
The people who love you deserve to know first.
The Family Plan is built for the partners, parents, and close friends who stay up wondering. One upgrade, activated inside the app, and your whole circle is connected.
The Compass Family Plan
A subscription upgrade that adds up to five alert contacts, group notification threads, and a caregiver dashboard. No additional hardware needed, activate it inside the app. Built for the parents, partners, and close friends who want to be the first to know.
What the upgrade includes
Up to five alert contacts
Add the people who matter most. Each one receives alerts the moment the app detects something worth flagging.
Group notification threads
Everyone on your list sees the same update at the same time. No one is left out of the loop.
Caregiver dashboard
A shared view inside the app so partners and parents can check in without asking every morning.
No extra hardware
Activate it in the app on the account you already have. Your device stays the same.
Built for
You shouldn't have to choose between independence and keeping the people who love you in the loop. The Family Plan closes that gap.
Pair with the Founding Member rate for $5/month on the base subscription. Both are locked in for life.
Why Open Compass
Built from the inside out.
I built Open Compass after years of managing a chronic condition that made every solo outing feel like a calculated risk. I knew the technology to help existed. What didn't exist was a device I'd actually want to wear.
You shouldn't have to choose between style and safety. So I started with that as a non-negotiable, and worked backward into the electronics.
The Compass Band and Pendant are general-wellness alert devices. They don't diagnose anything. What they do is watch for changes in your bio-signals and activity, and get your people alerted instantly. That's the whole job. Done well.
We're a pre-order right now because that's the honest way to fund a first production run. Your deposit validates demand. It goes toward your device. We build together.
