By reduxsoft

Open iTunes to buy and download apps.


Army Knife is a 10-in-1 Multi-tool for your iPhone and iPod Touch.

For less than a cup of coffee you can be prepared with nine quality tools to use at the most unsuspecting times.


The tools include:

- *NEW* Tip Calculator!
- Unit Converter
- Ultrasonic Whistle
- Protractor
- Heart/BPM counter
- Measuring Tape
- Digital Caliper
- Two levels
- Flashlight
- Emergency SOS Light

All of these tools fit nicely in your pocket, and all on one application.

Why pay for just one of these tools when you can have all nine for one low price?

Unit Converter:
This tool converts units in four different categories, Distance, Volume, Weight, and Temperature. The converter is very intuitive, and easy to switch between different units.

Ultrasonic Whistle:
This is a whistle that is on the higher range of human hearing. This can be used for multiple tasks such as repelling mosquitoes, training your dog, or annoying a teenager. The frequencies range from 440Hz to 22KHz, and can be pulsed or looped.

Measures angles from 0 to 180 degrees with accuracy up to a 10th of a degree.

Heart/BPM Counter:
Calculates beats per minute by how fast you tap the screen. To use this tool simply tap the pad 10 times, once with every beat. If you are measuring your heart then hold two fingers on your neck to find your pulse, and then tap the pad with each heartbeat.

Measuring Tape:
Can measure any distance. Simply place your finger on the screen and slide your iPhone/iPod underneath your finger until you reach the end of the screen, then lift your finger and place it at the opposite side of the screen and slide your iPhone/iPod again. Repeat this until you have slid your iPhone/iPod the distance you want to measure.

Digital Caliper:
Measure small objects precisely down to 0.15625mm.

Two Levels:
Make sure your surface is even with either the single axis or the dual axis level. Unlike most levels, this is able to do full calibration.

Helps you see in the dark, and the iPhone/iPod sleep has been disabled so your light won't shut off.

Emergency SOS Light:
Could possibly save your life. This tool will repeatably blink SOS in Morse code if you are ever in distress.

You can customize your Army Knife by tapping the shield logo and choosing one of 14 different colors and styles including camo, plaid, and denim.

Customer Reviews


the bpm tool helped out a lot when my heart was racing the other day. but there is one flaw with the unit converter, under the volume area it spells "litre" when it's supposed to be "liter", the level tool would be better if the long level was on the right side of the screen because the iPhone has buttons on the left side which causes unlevelness (if that's a word) but the right side is perfectly straight and even.


This tool is so useful! It could seriously save lives!!! It has an SOS light and a heart beat thing and lots more! It's loads of fun for only a dollar. Great app.

real flashlight

I think that it would be cool to add a flashlight from the iphone 4 flash
