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?

Turn your iPhone into a powerful Magnetic Detector and Metal Detector. Detect nearby magnetic fields, find hidden metal screws and nails, scan walls for magnetic objects, and measure EMF magnetic field activity in real time using your device's built-in magnetometer. Whether you're searching for metal fasteners behind walls, exploring magnetic sources, or measuring magnetic field strength, Magnetic Detector makes it easy to visualize changes in your surroundings. Magnetic Detector is handy for comparing readings around appliances, walls, and everyday objects. When used as a Metal Detector, it can help you spot nearby iron or steel items by showing changes in the magnetic field. FIND HIDDEN METAL OBJECTS Use your iPhone as a magnetic metal detector to help locate ferromagnetic objects such as iron and steel screws, nails, certain pipes, metal fittings, and other magnetic materials. Move your device slowly along walls or plasterboard to detect magnetic disturbances. Metal fasteners may help indicate the location of hidden wall studs. DETECT & MEASURE MAGNETIC FIELDS Transform your device into a real-time EMF magnetic field meter. Monitor magnetic field intensity with an intuitive digital gauge and observe how measurements change as you approach magnetic objects. The app displays magnetic field strength in: - μT (microtesla) - mG (milligauss) Earth's magnetic field is typically 25–65 μT. 1 μT equals 10 mG. POWERFUL DETECTION FEATURES - Real-time magnetic field and EMF magnetic field measurements. - Magnetic metal detection using your device's built-in magnetometer. - Interactive gauge displaying magnetic field intensity. - Audible warning when the magnetic field exceeds the configured threshold. - Automatic recording of measurements and timestamps. - Three-axis magnetic field readings (Bx, By, Bz). - 3D visualization of magnetic field measurements. - Room scanning to explore magnetic hotspots. - Support for microtesla and milligauss measurements. USE YOUR IPHONE AS A STUD FINDER Searching for hidden screws or nails in a wall? Magnetic Detector can help identify nearby ferromagnetic fasteners that may indicate the position of wooden studs or metal structures. IDEAL FOR DIY, EDUCATION & EXPLORATION Magnetic Detector can be useful for: - DIY enthusiasts and handymen exploring walls for magnetic fasteners. - Students conducting physics experiments and school projects. - Teachers demonstrating magnetic field behavior. - Engineers and technology enthusiasts studying magnetic measurements. - Anyone curious about magnetic activity around electronic devices, speakers, magnets, and other objects. HOW DOES IT WORK? The app uses the magnetometer integrated into your iPhone to measure nearby magnetic field strength. Ferromagnetic objects can produce or disturb local magnetic fields. As you move your device closer to these objects, the magnetic field readings may change, helping you identify potential magnetic sources. Tip: Shake your device to help recalibrate the magnetic sensor. Keep your phone away from magnetic accessories that could interfere with measurements. IMPORTANT INFORMATION Magnetic Detector is designed for personal, educational, and entertainment purposes. It is not a replacement for professional metal detectors, stud finders, electrical wire detectors, or safety equipment. Detection is primarily limited to nearby magnetic and ferromagnetic materials. The app cannot directly detect wooden studs, non-magnetic metals such as copper or aluminum, or reliably identify electrical wiring. Always verify wall conditions with appropriate professional tools before drilling. Accuracy depends on your device, distance, and magnetic interference. If you experience any issues or have suggestions, please contact us and include your device model and iOS version.
