How do/ would you use your phone as a tool?

What apps have you loaded? How do you plan to keep it charged?

have an old Motorola Razr with mini USB charge port, no apps but for charging... my Goal Zero 7w panel to charge my Guide 10 battery pack (4 Sanyo AA Eneloops) which has a charge cord from USB to miniUSB... the Guide 10 pack is stand alone for approx 2 charges.. 12vdc tubular charger in car... back up is my Garmin GPS which also uses mini USB via 12v tubular

I love my smartphone (Android). I definitely EDC it. It is a great convenience, but not something I would have as part of a survival plan. If it was there and working when I needed it for survival, that's a bonus, but not something to plan for and depend on.

Went on a search where the victim rescued himself by using his
phone as a flashlight to read his map and trail markers as well
as call for help.

I recently got an el-cheapo blackberry knock-off. To further prevent a relapse into my blackberry addiction, I've stayed away from smart phones and apps. I have downloaded a gps program though.

In terms of keeping phones charged, I used to carry a spare charged battery but haven't got one for my new phone yet. I've been thinking about getting one of those AA/AAA powered cel phone chargers for a back-up when I'm off-roading.

I don't need a GPS app for a smartphone, I have a Garmin GPS receiver (or 3 or 4 ) for that. But what I found really cool was an App for Celestial Navigation called AstroNav and another called Celestial by Navimatics. Other Apps such as Star Walk, Star Chart and Night Sky will assist in finding the correct celestial body. Very useful as a GPS back-up if you aren't on land. (They work even better on an iPad.) BTW, the iPhone has a very good electronic compass, but I have a real compass too.

I have a DroidX (android verizon smart phone).

I carry 3 extra batteries (ordered from China, about $4 shipped).

Small charger that works from AC or DC. Also charges my two small ham radio batteries (we carry 6 radio batteries, 3 each person). Set of clip cords for charger so I can hook it to any DC source 6v-14vdc.

Far to many apps to list specifically. Mostly I like
RAINDAR shows real time radar and storm intensity.

Many map and gps apps.

We don't depend on it, but it is surprising how many hot spots we find deep in the back country. Mostly on hills...

Lots of reference material. first aid, ham radio, special maps, and a whole lot more.

We don't depend on it and carry GPS, Ham Radios and other stuff. We don't depend on that stuff either. But having multiple items to do the important tasks (navigation, communication, data retrieval etc.) is comforting.

I have Google Sky Map on my tablet and love it. One of our other leaders has different version on his smart phone and it's pretty slick. We pulled it out on a hike the other night and figured out that that bright star in the sky was actually Saturn. An app that combined star gazing with navigation would be pretty useful.

Calender/agenda, bus schedule, weather, look up product reviews/competitor price while in store, FM radio, traffic status/webcam

I carry a spare battery, but never needed it so far.

Another problem with smartphone GPS aps is that the smartphone hardware tends to be awfully fragile, compared to a real GPS.
