Zero Bars // Still Works

Group chat for people who are together but out of signal. 1Bar passes encrypted messages from phone to phone over Bluetooth, so your Crew keeps talking where nothing else does.

I will use it on (optional)

We will use your email only to tell you when 1Bar launches. No ads, no sharing, and you can ask us to delete it at any time.

How it works

Start in seconds

You are on a trail, a ski hill, a boat, a festival or a job site. The signal drops and your group chat stops. 1Bar does not need a tower.

1

Start a Crew

Make a Crew and open it. A Crew holds up to 32 people.

2

People nearby tap to join

No phone numbers, no accounts, no sign-in. Everyone in the Crew needs 1Bar.

3

Keep talking

Messages pass from phone to phone over Bluetooth, encrypted, instead of through cell towers or Wi-Fi.

What is inside

Built for real conditions

Made for guides, trip leaders and the groups they look after, and for any Crew that spends time out of signal.

Chat

Message your whole Crew at once.

Short voice clips

Hold, talk, send. Handy when typing is not.

One-tap check-ins

Let your Crew know you are fine with a single tap.

SOS card

Alert your Crew when you need help. It goes to your Crew only.

Big, glove-friendly buttons

Readable in bright sun and in the dark, and usable with gloves on.

Quiet mode

Messages arrive without the buzz.

Why 1Bar

It started on a trail with no signal

Eight friends reached a trailhead with no cell service. As the group spread out along the trail at different paces, there was no way to stay in touch.

Later that same trip, one of us crested a hilltop and the phone showed a single bar of signal. That moment gave 1Bar its name. We built the app for the stretches in between, where there are zero bars and your group still needs to stay together.

Private by design

Brings your group together. Keeps it private.

1Bar is built so that we cannot read your messages, because they are encrypted between the phones in your Crew.

  • No accounts. No phone numbers and no sign-in.
  • No ads. No tracking.
  • We never receive your messages. Everything is stored encrypted on your phone.
  • Delete it all from Settings. Leave and forget deletes everything 1Bar keeps on your phone.

Good to know

  • Bluetooth range is limited. Distance, walls and terrain matter, and a message may take time to arrive.
  • 1Bar sends alerts to your Crew. It does not contact emergency services. In an emergency, call your local emergency number if you can.
  • Everyone in a Crew needs 1Bar installed.
  • 1Bar has not been released yet. We have not announced a launch date or price.
