## What is Toolbox PRO?

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:

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

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

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

- TESLAMETER
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

- METRONOME
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. 

- STOPWATCH
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

- TIMER
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

- SEISMOMETER
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

- PLUMB BOB
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

- SURFACE LEVEL
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,..)

- SPIRIT/BUBBLE LEVEL
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

- RULER
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

- PROTRACTOR
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?

### 5/5 — Tool Box Pro

*2026-07-05, version 5.4.0*

This is a good App, with a lot of features. Worth getting.

### 5/5 — Broken on iPad iOS 17 needs app update - but dev promises fix

*2026-06-29, version 5.4.0*

Update 2026/06/29: Developer responded saying fixes are pending. I raised back to 5 star review trusting in this app’s solid history.

Broken on iPad iOS 17 needs app update

### 1/5 — Still Not updated

*2026-06-28, version 5.4.0*

Ruler scale not adjusted for iphone pro max, it seems to be a long and not solved problem

### 1/5 — Broken on iPad iOS 17 needs app update

*2026-06-25, version 5.4.0*

Broken on iPad iOS 17 needs app update

### 1/5 — Toolbox Barometer Does Not Work At All

*2026-06-23, version 5.4.0*

Barometer has not worked for months

### 2/5 — Wo ist der dB-Messer? Barometer geht schon lange nicht mehr.

*2026-05-15, version 5.4.0*

Anders, als auf den Bildern zu sehen, ist in der Pro-Version kein Schalldruckpegelmessgerät enthalten. Das muss jetzt teuer separat gekauft werden. Das empfinde ich als Täuschung.
Der Rest ist ok.

Update (2026): App wird nicht mehr gepflegt, schade. Es gibt nicht mal einen Fix für das Barometer-Problem. Werde die App vermutlich deinstallieren.

### 1/5 — Nice if it worked

*2026-04-13, version 5.4.0*

One would think this would be a good app but not all features work. It is poorly done for sure. Especially the Baro doesn’t display inHg when set up correctly.

### 1/5 — Barometer

*2026-03-13, version 5.4.0*

The primary item I used in this app was the barometer which seems to no longer be functional.

### 1/5 — Not working

*2026-03-10, version 5.4.0*

Some tools like barometer do not work pls update

### 2/5 — Betrug

*2026-02-19, version 5.4.0*

Das erste Bild zeigt eine Dezibel Messung und nach dem Kauf muss ich dann feststellen dass diese Option direkt fehlt. Zudem lässt sich die Sprache nicht einstellen wie angegeben. Ärgerlich
