Ureka Lantern

iPhone

Get Ureka Lantern on your iPhone.

Early access runs through Apple’s free TestFlight app. It takes about three minutes.

Status: early testing, by invitation. Ureka Lantern is not on the App Store yet. We are adding testers a few at a time. Step 0 below tells you how to ask for a spot.

Step 0. Ask for an invitation

Use the contact form. Write “iPhone early access” and, in the reply email box, enter the email address of your Apple ID (the one you use for the App Store). We add you to the test list, and TestFlight emails you the invitation. Please do not send anything else personal.

Quick steps once you have the invitation

  1. Install TestFlight. It’s Apple’s free app for trying early apps: TestFlight in the App Store.
  2. Open the invitation on your iPhone. Find the email from TestFlight (check Junk if it is missing) and tap View in TestFlight, or Start Testing.
  3. Tap Install. Open Ureka Lantern from your Home Screen.
  4. Add your people. Enter up to three trusted contacts by phone number (start with + and the country code if it is not a US number) or email.
  5. Try it. Tap Share my location. Allow location when your iPhone asks. Your Messages app opens with the message filled in, and you tap Send. Use a test check-in first, so you know what your contacts will see.
  6. Tell us what you think. In TestFlight, open Ureka Lantern and tap Send Beta Feedback (you can attach a screenshot).

What you need

  • An iPhone with iOS 15 or later.
  • An Apple ID signed in on the iPhone.
  • No payment. You won’t be charged during testing.

Good to know

  • Test builds stop working after 90 days. TestFlight tells you when a newer build is available.
  • Ureka Lantern sends nothing to us. Location, photos and your contacts stay on your phone until you hand them to Messages or Mail. See the privacy promise.
  • It is not an emergency service. In an emergency, call 911 or your local emergency number. See the safety notice.

Trouble?

I did not get the invitation email

Check Junk and Promotions. Make sure the address we have is the one your Apple ID uses. If you gave a different one, send us another message with the right address.

TestFlight says the app cannot be installed

Your iPhone needs iOS 15 or later. Update in Settings, General, Software Update, then try again.

The build has expired

Open TestFlight and tap Update if a newer build is listed. If not, send us a message and we will upload one.

Messages opens but nothing is sent

That is how iPhone works: apps cannot send texts for you. Tap the blue Send arrow in Messages. Ureka Lantern will only ever tell you the message was handed to Messages.
