AudibleSpeed (GPS Speed Monitor) - CONTINUOUS AUDIBLE MONITORING of your current speed!!

By OK Apps

Open iTunes to buy and download apps.


AudibleSpeed (GPS Speed Monitor) provides CONTINUOUS AUDIBLE MONITORING of your current speed at all times!!

This utility app allows you to define one or more Speed Ranges and associate each range with a sound effect and a color code (any RGB color).

It will then track your speed using your iPhone's GPS unit (built-in in all iPhone 3G/3GS models) and will:

- display the current speed in digital and analogue ("speedometer") formats, as well as plot a graph chart (covering the last 80 seconds);

- play the associated sound effect whenever your current speed enters a defined range;

- (optionally) replay the sound effect repeatedly with a specified interval as long as your speed stays within that range (this is configurable individually for each range);

- change the screen frame/background color to the color associated with that range;

- display the range name (or associated sound effect name if range name is left blank) and some other parameters;

- it also tracks and displays the MAX and AVG speed for the session, as well as time and distance traveled.

When the GPS satellites signal is unavailable (e.g., inside tunnels, between skyscrapers, under big bridges, indoors, etc) and/or GPS speed data becomes "stale" (older than 5 seconds) it will play a warning "beep" sound and flash the frame/background color black and white.


On the very first use (once-off), it will guide you through:
- a warning/disclaimer screen (please read carefully),
- then the Settings screen - where you can choose your speed measurement units (MPH, KM/H, etc),
- and then it will then create a set of sample speed ranges with values that best illustrate the concept taking into account the speed measurement units selected in Settings (you can later modify or delete these sample ranges - just as if they were your own created by you).


Because this app uses the GPS unit to obtain speed data, it must be allowed to access "Location Services" when prompted to do so.
Also "Location Services" must be turned "ON" and the "Airplane Mode" must be "OFF" in the iPhone's standard "Settings" page.

Besides using the GPS data to determine current speed, this app is also retrieving and displaying your current Long, Lat and Alt, but it is NOT actually "tracking" your location as such - i.e. it does not store or report or make any use of Long/Lat/Alt data other than displaying on screen and calculating the distance between previous and current location point (to aggregate total distance traveled).


It comes prepackaged with 90 thoughtfully hand-picked sound effects to choose from.

Continued use of GPS running in the background can dramatically decrease battery life.

(Therefore, if this app is used in a vehicle, we highly recommend that you plug your iPhone into a compatible in-car charger or charging cradle/dock.)

*** This application is provided for informational and entertainment purposes only.

The consumer-grade GPS technology (like the one found in iPhone 3G/3GS or any other GPS-enabled phones) has substantial inherent limitations regarding its availability, accuracy and reliability - especially in regards to speed data.

Therefore it can not and MUST NOT be used for primary navigation.

You should also check your local laws, rules and regulations regarding the use of mobile phones and other mobile devices while driving, and comply accordingly.

What's New in Version 1.2.1

1. Added 'Auto-Stop' option in Settings.

Although the majority of our users really like and enjoy the app's capability to continue to work in background (under iOS 4+ multitasking), some other users contacted us asking for an option switch to be able to tell the app to auto-stop active work (and respectively stop GPS chip use) when the app is moved from foreground into the background.

So, we are now adding this option to keep ALL users happy!! :)

2. Enhanced support&feedback contact capabilities and links and added social media (Twitter and Facebook) contact links in 'Info/About' screen.

We welcome all inquiries, feedback, comments and suggestions - get in touch and stay connected! :)
