There have been many times where I needed a Caliper, with a digital output, a Plumb on the off chance I needed to know if my verticals were accurate, and a Protractor again with a digital output. This company is offering more applications in the near future (update?) however right now, for $0.99 cents, you get the following:
• Alarm Talking Clock • Caliper • Clinometer/Inclinometer • Decibel/Sound Meter • Flashlight • Metal Detector • Plumb bob • Protractor • Ruler • Voice Battery Tool • Voice Compass The graphics were designed by Danielo Lipele and it almost has a Steampunk feel to it.
Some of the applications in this program are more entertainment purposes, however you can’t just buy a few, it’s a bundled deal. You can’t go wrong with the price, and frankly, the Caliper really sealed it for me.
