Prep your Android phone to help you during a disaster

Swimming off Louisiana a few sweltering, torrid days before Hurricane Katrina smacked into New Orleans in 2005, the Gulf Coast’s water felt like a stifling, hot bath.

I discovered later that warm ocean water is one of the factors that can increase hurricane strength.

FEMA also reckons they learned something that year. I’d hope so. The reality is that a weather event on the scale of Katrina could happen again, and public safety agencies can get overwhelmed.

My instinct, living in wobbly earthquake and drought-ridden, tinder-dry wildfire country we know as sunny California, is go “prepper,” and mitigate trouble by getting organized.

Don’t get caught off guard

I reckon prepping for disasters today is easier than it was in Katrina’s communication-light, feature-phone-ridden era, partly because we have two technological advances we didn’t have then: smartphones and social networks. (The iPhone was released two years after Hurricane Katrina.)

I’ve prepped my Android devices, and I think I’ve gotten up to speed for this year’s hurricane season on the right coast—and El Nino, wildfires, and an overdue earthquakes on the left.

Here’s how to prep your Android phone to be more useful during natural disasters.

Social networks

Install the Facebook and Twitter Android apps. Then, friend neighbors in your community, and add local authorities to a Twitter list. During an event, if wireless data is available, you’ll see local incident updates spreading virally through your Facebook and Twitter feeds.

In the case of Twitter, use hashtags during an event to search for disaster terms and locales, for example: #earthquake, #lafire, or #wildfire.

New Jersey’s 2012 Super-storm Sandy proved the utility of Twitter and Facebook: Storm updates were organized there by individuals, and agencies like the Red Cross now hire workers to update social network pages.

Radio

Many Android devices include a native, hardware-driven FM-band radio—it uses the headphone cable as an antenna, and doesn’t require an Internet connection (which is often disrupted). Look for it, pre-existing, in the app drawer, or hidden in a stock media app. There are some radio apps in the Google Play store, but they're often tied to specific hardware, so you'll need to do a little searching to fine one that works with your phone.

Much continuous news broadcasting is on the AM band, though. And useful disaster press conferences are often broadcast in their entirety on AM.

Android hardware doesn’t include an AM radio, so you need an Internet-driven app too. The free TuneIn Radio app, available in Google’s Play store, will let you listen to the FM top-of-the-hour news, plus in-depth AM talk, and official weather radio. It requires an internet connection, though.

Public safety feeds

Scanner Radio is another free Android app. It streams insider-information police scanner feeds from fire and law enforcement agencies, over your phone’s Internet connection.

Install both TuneIn Radio and Scanner Radio, then browse for stations by location.

Voice-over-IP

What happens in a power outage, when there’s no home-base Internet, wireless data Internet, or cellphone voice service? The answer is to use VoIP and public Wi-Fi, if you can find it.

Viber is a solid app that will replace failed voice cellphone service.

Viber lets you make voice calls over the Internet using your existing handset. With its paid service, called Viber Out, a moola top-up gets you calls to out-of-area working landlines and cell phones. Apps like Skype let you make over-the-net calls to regular phone numbers, too.

Paid wi-fi

If you can’t find functional, free Wi-Fi in the disaster zone, the Boingo app can help.

Boingo is a free app for locating Wi-Fi hotspots, with pay-as-you-go rates that will let you search for, and then connect to paid hotspots like FedEx Office. The pay-as-you-go price varies depending on location.

No connection at all

If there's a major catastrophic event, and you find there’s nothing, you think you’re on your own, right? Well, maybe not.

One little-known quirk with mobile network technology, is that SMS text messaging uses significantly less bandwidth than any other carrier-provided service, like voice. It actually piggybacks on the control channel; the intermittent pings from cell towers that let your phone know when and how to connect. This means that texts can sometimes get through, even when voice calling and data is unavailable.

Try sending an SMS text normally. You may be surprised to find SMS texting works sometimes, even if you don’t see signal bars.

Internet via text

There’s a unique idea out there for taking advantage of SMS’s stripped-down network bandwidth requirements.

The free beta app Be-Bound lets you connect to the web, without a data connection. So it’s useful in near-dead-zones. It works by sending chunks of data via SMS.

Buy credits in advance of an incident via website, and then choose from weather, e-mail or Twitter feeds, for delivery over text when trouble strikes.

Messaging phone-to-phone

TinCan is another way to use your phones networking without the traditional Internet. This app uses Android’s little-used peer-to-peer Wi-Fi radio function. So instead of sending messages through a wireless network, or Internet-connected Wi-Fi signal, Tin Can lets you hop messages directly from phone-to-phone over short distances.

Unfortunately, the usefulness of an app like this is limited to how many people nearby also have it installed. In an emergency, will there be someone else within range of your phone's Wi-Fi radio who also has the app?
