Transform your mobile device into a global satellite communication and navigation tool when you pair your inReach with our Earthmate app, enabling access to these exclusive features: send and receive text messages anywhere in the world, worry-free navigation and journey tracking, global SOS, unlimited access to downloadable topographic maps and NOAA charts on your paired mobile device, automatically syncs with your mobile device's address book for easy texting and pairs easily via Bluetooth.

Stay connected with family and friends and interact with GEOS, the 24-hour emergency monitoring center anywhere on Earth. Plus, you’ll receive confirmation when your messages are delivered. You can also post messages to Facebook and Twitter and let others track your breadcrumb trail online.

As an inReach owner, you also have exclusive access to download unlimited detailed topographic maps from DeLorme available through the Earthmate app. The maps are cached on your mobile device, so they are viewable even when out of cellular coverage. The display integrates with your mobile device’s GPS signal to pinpoint your location.

For worry-free navigation, the inReach GPS signal (accurate to +/- 5 meters) is integrated with the map displays. Since navigation doesn’t rely on the mobile device’s native GPS, there is less demand on its battery, which can be especially important in remote areas.

NOTE: An inReach satellite communicator is required to use Earthmate and download maps. Maps should be downloaded via a WiFi connection prior to leaving on a trip. DeLorme’s global topographic maps include elevation contours, land cover, highways, streets and back roads, lakes and streams, places of interest, and trails.

• Send and receive 160-character, free-form text messages to and from any cell phone number, email address, and other inReach users. No cell coverage required!
• Interactive SOS - Trigger an SOS from anywhere in the world with automatic GPS location tracking. Interact with our 24-hour emergency monitoring center via two-way text messaging to describe the nature of your emergency and stay in touch throughout the rescue process.
• Message delivery confirmation - Audible alerts and on-screen cues confirm communication with the satellite and indicate two-way message delivery.
• Unlimited access to download detailed topographic maps and North American NOAA charts when paired with your mobile device. Unlike streaming maps on most cell phone apps, downloaded DeLorme maps remain cached in the Earthmate app even when you’re outside cellular coverage.
• Follow-me/find-me tracking - Turn on and turn off tracking to share your GPS coordinates, course, speed and elevation in real-time with friends and family, tracking intervals can be configured between to minutes and four hours.
• 100% global satellite coverage through the Iridium satellite network with no gaps, fringe or weak signal areas.

    Doesn't work on my Nexus 4 (4.4.3). After it opens, it shows the title graphics, and then crashes.

    Why is the app difficult for users to use? Apps should make things easier.

    I was a little hesitant about committing to this product because of all of the complaining I had seen about it, but it has worked fine for me. Texts go through after about 10 seconds and you can automatically check for incoming messages every 5 minutes or manually. I look forward to using this more.

    works OK on my HTC sensation but crashes on launch on my Nexus 7. Disappointing as I like to use the larger screen - and i carry it with me when travelling. I can't read small scren without my glasses and if they got broke in an accident I would find it hard to use my inreach without it being linked to the Nexus !

    On my second device and thus far the experience has not improved. I fear I've wasted more money on an unreliable beta product.

    it worked great on my Sony xperia ion but crashes on startup on my Samsung galaxy s4. I thought it worked when I first got the new phone, but not after the os was updated. no way to know now. delorme support was of no help - said they'd never heard of this problem. boo.
