Why balloon teams use it

Built for launch day.

Everything you want from lift-off to recovery — and nothing your class or followers need to install to watch.

  • Follow along without an app

    Send one link. Your class, department, or the public follow the balloon live in any browser — no app, no sign-up.

  • Find your payload

    The payload phones its position home as soon as it drops back into coverage — so you drive to the landing spot instead of grid-searching a field.

  • The whole flight

    The path draws whenever the phone has signal — and the stratosphere has none. What it records out of range is sent once it's back; keep the complete flight to replay and log afterwards with Track Loading.

How it works

On the map before the countdown.

  1. Grab the app

    Install Real-Time GPS Tracker 2 from Google Play. It's free.

  2. Press start

    Pick a name and tap start. You show up on the map right away.

  3. Send the link

    Share one link with your team and followers. They watch the balloon climb live, with the flight path drawing behind it.

Good to know

Weather-balloon questions, answered.

Does my class or team need an app?

No. They open your link in any browser — phone or computer. Only the payload runs the Android app to broadcast its location.

Does it work at high altitude?

There's no mobile coverage in the stratosphere, so the phone can't report while it's up there. It sends its position whenever it has a signal — on the way up, and crucially as it descends back into coverage, which is exactly when you need a fix to recover the payload. Positions it records while out of range are kept on the phone and sent once it's back. To keep and replay the whole flight afterwards, add Track Loading (Premium). Live sharing is free.

Can the whole recovery team follow along?

Yes. Everyone with your link sees the payload on the map whenever it's reporting — so you can converge on the landing spot together.

Can I put the live map on our project or university page?

Yes — that's the Website Framing Premium add-on: embed the live balloon map on your project or department page so classmates and visitors can watch launch day. The plain shareable link is always free, and so is core live sharing.
