The most handy measuring tool kit in the world. Turning your iPhone or iPad into a multi functional measuring device with: metronome, stopwatch, timer, seismometer, ruler, surface level and many more.

Currently, there are 14 measuring tools + Flashlight in the tool box:

It gives you a nice and clear local atmospheric pressure, obtained from the barometric sensor in your device

This tool takes advantage of the built in GPS to give you the precise elevation above the sea level.

A pretty and well-made compass for navigation, traveling and direction reference purposes.

A professional sound meter, precisely measures the sound pressure level all around you.

It takes advantage of the built-in magnetometer in your iPhone/iPod touch, allows you to monitor the strength of magnetic field all around. There are a range of real-life applications for this useful item, such as: metal detector, AC magnetic fields, or finding low-magnetic places for sleeping

It is the most precise and stable metronome on the app store. Whether you are a musician, a music teacher, a beginner at playing music or even a golfer, this tool provides you a set of powerful features that can satisfy all your needs.

Whenever you need a precise and professional stopwatch for sport activities like: sprints, jogging, this tool is a must have. Among its features are: intuitive interface, lap and split modes support, or send log results to your email

There are unlimited applications of using timer in daily life, such as: egg timer, tea timer, cooking, alarm clock, etc. The timer tool satisfies all of those needs by many of its features: up to 5 timers running simultaneously, count down and count up support, intuitive and convenient duration setup using preset and gestures

Taking advantage of the built-in accelerometer in your iPhone, this tool detects and visualizes any vibrations and moves of the iPhone. So, why not using this excellent feature to help your iPhone self-protected like a car when combined with an alarm? Or another great application is to test how smooth the car is on a test drive

This is an instrument to check if an object is perfectly vertical/plumb and has been used since the time of the ancient Egyptians. It suits any types of your needs, such as: hanging objects, carpenter work, brick layer or building construction

This tool facilitates the measurement of the slope of whatever surface you want to check. Most importantly, its accuracy is ensured at the maximum level by the support to different sensitivities that allow you to detect subtle slopes (floor leveling, furniture arrangement,..)

It is a simple but extremely useful tool in the set to check if an object is balanced. Its applications range from entertained purposes such as checking pool billiard tables in the bar to serious usages like constructions, carpenter, etc

The ruler helps you precisely know the lengths of objects all around you, such as pens, tables, pictures. We built it to become even more than just a normal ruler: longest distance measuring capability, and up to 6 units support

Have you ever forgotten your protractor at school or when you urgently look for a protractor to measure any kind of angles in real life?

Instant crashes. Will not open at all anymore.


It instantly crashes on both iOS 11.0 and 11.0.1. I have an iPhone 7 Plus. I’ve tried it many times with no luck. All my other apps work perfectly.

Your response worked. Thank you. I’ve revised my rating to five stars. Thank you for your response and for working hard to once again make this an excellent app.

Does everything you would expect and more.

Precision and accuracy, while not the same, are very much present in this app. I have yet to find a problem with this app and have found it very helpful whenever I have used it, which is often.

Not so good on iPhone 8plus


This app worked wonderfully on my old iPhone 5s, but I just got a new iPhone 8plus today and all it does is crash on the new 11 program. OK- a day later and they must have updated the app because it now works wonderfully again!
