Smartphone Apps for Cops

Smartphone software applications bring targeted tools to improve communication, manage information, translate other languages, and gather useful information while in the field.

There are add-on photography applications for smartphones that will be useful for you. For the iPhone, there's Camera Plus Pro, which allows you to control some aspects of camera function not available in the native software. This includes delaying the shutter release until the camera is relatively steady and a "burst" mode to take several frames at a time. Android has Camera Pro, with similar features. Another iPhone camera app you might find useful is Camera Camouflage, which has a screen that looks like an incoming call (and will even ring), but actually takes a picture each time you speak into the mic.

Information Management

You're going to be handling a lot of information, some of it pretty random. Good investigators are good note-takers, and record their observations regularly, usually in a pen-and-paper notebook. The downside of this method is that paper notebooks have limited capacity, and aren't searchable. Notes taken on your smartphone are searchable, have infinite capacity if you allow for expansion onto a memory card or "the cloud" (data maintained on the Web or elsewhere where you can retrieve it wirelessly), and can be associated with pictures and other data.

Evernote offers apps for most PC, Mac, and smartphone OSs, and is versatile enough for law enforcement or any other use. When you see something you want to remember or keep track of, send it to Evernote. This applies to photos, text notes, e-mail, Web pages, articles, and just about anything else. Evernote stores a copy on your device and on the Evernote server, where you can retrieve it at your leisure. You create tags and categories to fit your own needs. A free Evernote account allows you 40 MB of uploads per month, which is plenty enough for most people. If you get to be an Evernote junkie, you can get a premium account for $5 per month and upload 500 MB.

Another type of information manager is eWallet, which offers versions for most smartphone platforms, PCs, and Macs. eWallet is for the kind of information you might carry in your wallet: account numbers and passwords, serial numbers, prescriptions, clothing sizes, PINs, etc. It comes with template "cards" for most any kind of information you're likely to need, and there are blank general purpose cards and design-your-own versions.

The database is encrypted on whatever device you have, so if it does fall into the wrong hands, it will be useless without the password. When you make a change on one platform, you can synchronize it to the other, so your mobile and desktop files stay concurrent. Among the files in my eWallet are cards for each one of my guns, with make, model, serial number, and place of purchase. I have similar files for my computers and other electronic gear. If something goes missing, I always have its details.

You can use your smartphone to replace some of the reference books and "cheat sheets" you've collected (or you will create). Droid Law is a free database for Android phones, and is necessary to run any of the various state and federal code references they have for sale. Why carry a book around when you can have the entire criminal and/or vehicle code for your state on your phone? There are similar applications for other smartphone platforms, although you may not find a ready-made solution for your jurisdiction.

If not, consider making your own. Every smartphone platform has one or more flat-file database applications available. It wouldn't take all that many evenings to create your own criminal code database, and populate it by cutting and pasting from the online version of your state's statutes. You might even be able to sell your work to other officers (but check copyright issues before you try).

Foreign Languages

Do you speak all of the languages used by the people in your community? Me neither. Every smartphone OS offers "phrasebook" applications you can use for the occasional encounter, even if the language isn't especially common or frequently encountered in your area. An iPhone app called "Spanish for Police-Audio Phrasebook" goes one step farther by including a sound file of every phrase, so if your Spanish enunciation isn't up to par, the app will say it for you.

It's almost impossible to list all of the apps available for police smartphones, and the ways they can be used. If I tried, it would be outdated by the time this appeared in the magazine. Just know that if there's some task where you want to use your smartphone, there is probably a way to do it and "an app for that."

Smart Cop's Smartphone User Guide:

  1. Don't keep or transmit messages or pictures you wouldn't want to see attributed to you in the newspaper. Even if the phone and the airtime are your personal property, these things have a way of coming back to haunt you.
  2. You aren't any more skilled at playing with your phone or text messaging while driving than the 17-year-old you ticket for it. Moreover, when you drive into a tree, it's that much more embarrassing.
  3. Set your phone so that it requires a password every time you use it. Yes, it's a pain in the butt, but not as much as if Tommy Tweaker gets it and has control of your address book, photos, and whatever else might be on there.
  4. Consider getting a phone and a service that allow you to wipe and/or disable the phone remotely if it's stolen or mislaid. It might cost more, but it will be worth it.
