We really hope you never have to call 911.

But because it could happen to anyone, anywhere, at any time -- someday you may need to make that dreaded call.

Now you can place that emergency call with a minimum of taps on your phone and without having to fumble around with your keypad.

The Goal.

The single goal of NineOneOne was to create an application for the iPhone that would drastically, yet practically, reduce the number of taps to make the call to 911.

A typical call to 911 would take approximately seven taps: Home, Phone, Keypad, 9, 1, 1, Call.

We knew we could do better.

NineOneOne reduces the required number of taps down to four in its default configuration: Home, Launch App, Big Button, Confirm. This can be further reduced down to only three taps in a configuration setting, which bypasses the confirmation step altogether.


The Big Button leads the way to safety - large enough to find and tap in an emergency setting. NineOneOne prevents accidental dialing, while remaining incredibly easy and straightforward.


NineOneOne's Emergency Number can be set to any number, and the Dial Warning can be disabled to reduce number of taps even further - allowing you to make your emergency call immediately.

The Story.
NineOneOne was designed and developed by Evan K. Stone. It was inspired out of the simple need to be able to contact emergency services in one's area quickly.

Other projects were put on hold to get this out the door and into the hands of people who needed it the most.

"I designed this application because I was in a an emergency situation in my car and needed to contact emergency services. However, it was too difficult under the circumstances, and I was unable to make the call. What I really needed was an app that would dial emergency services easily and in a minimum of taps. That's how NineOneOne was born." - Evan K. Stone, Developer of NineOneOne

Nice Work towards NextGen 9-1-1

I just made a test call. It routed through Mckinney's 911 system as a Phase II call with my ANI and the address of the cell tower. This developer is working with the 911 entities and telcos. Hope part of the app cost goes to the 911 entities. The next step is for the actual call location to be displayed on a map for accurate dispatching. I've work in the 9-1-1 industry for almost 25 years and it's great to see this development and testing. Good stuff.
