GumLeaf is not an emergency service. In an emergency, contact local emergency services (911, 112, etc.) — never rely on GumLeaf for safety-critical information.

01 · The route

How it works

  1. 01

    Text a question

    Any question, from any phone — including iPhone satellite messaging, Starlink direct-to-cell, or a Garmin inReach in phone-number mode.

  2. 02

    Get a right-sized answer

    GumLeaf replies in a single text: real forecast data for weather questions, a concise expert answer for everything else.

  3. 03

    Reply MORE for depth

    Want the full picture? Plus members reply MORE and GumLeaf sends the extended answer it kept aside for them.

02 · The coverage gap

Most of the map has no signal

~10% of the Earth's surface has any cellular signal at all. The other 90% — oceans, ranges, backcountry — is a dead zone.
111.7 M acres of US wilderness where cell towers are effectively banned by the Wilderness Act. Off-grid, on purpose.
1 text is all it takes — satellite SMS carries your question out where data never reaches, and carries the answer home.

Sources: cellular reaches only ~10–15% of the Earth's surface (industry estimates); 111.7M acres of designated US wilderness (wilderness.net).

03 · Why GumLeaf

For the moment your bars disappear

Summit ridges, canyon camps, the last 40 miles of washboard road. If you can send a text — including by satellite — you can get an answer, no matter how far the nearest tower is.

Real forecast data

Weather answers are grounded in live National Weather Service and MET Norway data — the same sources meteorologists use — not a chatbot's guess.

No app, no account

Nothing to install, no login. Your phone number is your account. Three free answers every month, forever.

Please plan like GumLeaf doesn't exist. SMS delivery — especially over satellite — can be delayed or fail entirely. Never depend on GumLeaf for medical guidance, navigation, rescue, or any situation where a missing or wrong answer could put someone at risk.

Questions, answered

Can I use GumLeaf in an emergency?

No. GumLeaf is an informational convenience, not a safety service. Messages can be delayed, lost, or answered incorrectly. In an emergency contact local emergency services (911 in the US, 112 in Europe); on satellite iPhones use Emergency SOS, and on Garmin devices use the dedicated SOS function.

How do I get started?

Two ways: text any question straight to the GumLeaf number, or enter your mobile number in the form at the top of this page and GumLeaf will text you first — reply to that text and you're off.

How do I activate GumLeaf Plus?

Tap the upgrade link GumLeaf texts you, pay with Apple Pay or Google Pay (or a card), and you're done — your phone number activates automatically the moment checkout completes. Just text your next question.

Can I move my subscription to a new phone number?

Send a note through our contact form from the email you used at checkout and we'll move it over.

What does the free plan include?

3 answered questions every month, resetting on the 1st. Full-length MORE expansions are a Plus feature — free answers are still complete, just concise.

Does it really work over satellite?

Yes. iPhone Messages via satellite (iPhone 14 and later), T-Mobile/Starlink direct-to-cell, and Garmin inReach in phone-number mode all deliver to GumLeaf as ordinary SMS. Tip: satellite texting is slow — keep questions short, and give replies a few minutes.

Why a koala?

Because a koala is nature's expert at doing a lot with almost nothing — exactly what you need off the grid. Eucalyptus is barely food, so a koala never wastes a move; GumLeaf answers the same way — one text out, one tight answer back, no feeds or ads. Koalas thrive on next to nothing; GumLeaf runs on the oldest, most stubborn pipe in telecom, plain SMS, the one channel that still works when apps just spin. And legend has it "koala" means "no drink" — they get all they need from the leaves, the way GumLeaf needs no data plan, no Wi-Fi, no download. If one little text can escape, one answer can come home.

What do you store about me?

Your phone number, a usage counter, your last answer (kept 1 hour so MORE works), and — for Plus — the link to your subscription. Question text is processed by OpenAI to generate answers and transits Twilio like any SMS. Full details in the privacy policy.

How do I stop messages?

Text STOP at any time — that's handled at the carrier level and GumLeaf will never text you again unless you text START.
