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 13 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.

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?

The Teslameter alone makes this app awesome. For one; as an Electrician I can use this app to check for Live Wires w/ just my iPhone! Some other cool uses are to like search somebody for a ‘bug’, microphone, or if they’re trying to hide their cellphone… Maybe only useful in the movies but still, it’s possible. Just for Do-It-Yourselfers’ there’s multiple types of Levels & Protractors, plumb bob; to get all your projects together perfectly by just using your phone! Replaces half a toolbox/tool belt when combined w/ the ‘Augmented Reality Measuring App; which is pretty dang accurate. Great for chopping on 2x4’s w/ the Measure App & this Toolobox app. No need for measuring tape when you always have the phone in your pocket! Nice to have, I recommend Toolbox

So Far it’s Great!!!

I’ve only had this app for a short while, but the flash light is super bright and that’s so great! Especially compared to other ones I’ve tried. The other little tools are very cool. I would like to comment on the constant pop up requesting me to upgrade. I find that to be completely annoying and if I wanted to upgrade I would have already done so. I cannot afford to pay for apps due to severe and chronic health problems, so please be considerate and remove the pop up. We are not idiots and we are all aware we can upgrade if we want, but it’s very very frustrating to have to continuously deal with pop ups and questions on upgrades from apps! Thank you.

Broken on iPad Pro

I wish I’d backed up the previous version so I could revert! Tried to run v4.6 on 2 iPad Pros, iOS 11.3, and it crashes on both as soon as I try to do anything. Searched for a way to contact the developer but couldn’t find one. Maybe it’s accessible from the app (if it didn’t crash).

Actually, what happens is that iOS still shows it as running from the Mission Control screen, but no app windows or functions show.

I hope there’s a bug fix SOON.
