11 Best apps to check roof pitch (Android & iOS)

You will surprise nobody any more with screen rulers, virtual designers of a premise, and other appendices for designing. But there are also other convenient tools which will help you in work on projects or your own house.

Some of our smartphone sensors allow us to use fairly unusual tools, such as a speedometer or compass. But what if your smartphone could become something else?

Many people design their own homes. The design process also includes planning for roof cover changes. In order for you to calculate everything correctly – and the number of materials, and even the angle of slope – you will need special tools.

But even if you do not have them, your smartphone will help. There are several special applications that can use smartphone sensors to determine this data. We’ve found 11 special applications that can help you measure tilt angles – many of which will work with any material or building.

ImageMeter – photo measure

imagemeter - photo measureImageMeter is a universal tool in your smartphone. With it you can easily measure angles, lengths, and even distance in images.

You don’t have to draw sketches manually and measure scale for drawings – ImageMeter will do it all for you. ImageMeter measures with a camera and uses laser devices that measure distance and transmit data via Bluetooth.

The application allows measurements to be made with a “reference” object. To begin with, you bring an object whose length or angle you know to the camera and based on these results the application will calculate everything by itself.

On the basis of the reference measurement, you calculate the indices of other objects in your house – roofs, corners, room sizes. For convenient presentation, ImageMeter uses metric and imperial units. You decide which images and photos are worth measuring – you can optionally upload them to the cloud storage.

Ruler – Bubble Level – Angle Meter

ruler bubble levelThe need for measurements exists in absolutely different areas of life and work. You can only do the construction or simply change something in your own home – you will need special tools anyway.

In the application from 1 Bit, you will find 3 tools at once, which are reflected in the name – a ruler, a bubble level, and an angle meter. You can use them at your own discretion and anywhere you want.

In order to measure the angle, you need to place a point on the camera in the corner of the object, and then make all the necessary adjustments. The line to be placed according to the object will be displayed on the screen.

Then the length is already set and the angle is calculated. If you work with other tools, you will be able to adjust the units of measurement and even fix the resulting value, so that the indicators won’t be confused.

It is worth calibrating the accuracy of each measurement that you will make. This application will be a really useful tool for household and work.

Bubble level & angle meter: level work tool

bubble level angle meterWe think you understand that most such applications combine several useful tools at once. This level work tool application combines two similar tools – bubble level and tilt measurement.

Developers call their product the best for surface measurement, but whether this is the case is up to you. It should be noted that the level work tool is easy to use and has a simple and clear interface.

Some applications simply give you a virtual protractor, which you use on your own. The level work tool calculates the arctangent between the two axes of surfaces, thus providing accurate results and indicators.

Of course, the accuracy varies depending on the quality of your smartphone’s sensors. You can also specifically switch on the protractor mode, which allows you to measure anything.

Using smartphone sensors, you can easily move the protractor and measure even the smallest and narrowest corners. Lock the screen rotation for increased accuracy right in your level work tool.

Protractor™ by Tue Nguyen Minh

protractor tue nguyen minhWe already mentioned that there are applications that just provide you with a virtual protractor. Protractor is exactly that kind of application – but sometimes that’s enough to get you the measurements you need right now.

With the help of the utility, all measurements will go quickly, and you can record the results in your notebook or anywhere else.

The Protractor interface isn’t surprising – you’ll see a protractor on the screen after launch and you’ll be able to take all measurements with it. Accordingly, visual control is intuitive – especially if you have already used it in real life.

Measurements can be made both in degrees and in radians. The Protractor also has an integrated bubble level, which you may need for your design. For calculations, it is possible to use the built-in converter with a set of units of measurement.

Protractor Tool – Transportador

protractor tool transportadorTransportador makes it easy for you to measure all the angles around you. If you need to measure the level of your roof slope right now, or if you want to add a measure of the angles to your calculations, the application will quickly determine the right numbers for you.

In total, Transportador has three different modes of operation: manual angle measurement, digital inclinometer, and automatic angle measurement. You measure tilt angles, object verticality, and other indicators.

For automatic measurements in Transportador, you will need to select a horizontal base figure. On the roof, it can be the base or the level at which the foundation of the house is located. The slope is displayed more accurately on the digital display, where all the rails and signs will be located as well.

To fix the changes, it is recommended to press pause. It is also possible to calibrate the device and adjust the correct horizontal position of the smartphone for accuracy in Transportador. Turn the camera on and start measuring – it will not take you long.

Protractor by keuwlsoft

protractor keuwlsoftProtractor is another application that represents a virtual protractor. It is designed exclusively for measuring indicators and angles, so if you are looking for a multifunctional utility, it is better to consider other options.

The Protractor interface itself is quite simple: on the screen, you see the protractor and a few work buttons – and that’s where it ends. Minimalism in all its manifestations!

In order to measure something in space rather than on the screen, the application suggests you turn on the camera and point it at the object of interest. There is also a special pause button, which allows you to fix the image for accurate measurement.

After that, the horizontal and vertical lines are adjusted, which will be responsible for the resulting angle. For accelerometer calibration, there is also a separate point, which is better to use before all measurements.

Copy your measurements to the clipboard so you can send them by message or save them as notes on your smartphone.

iLevel – Protractor & Level

ilevelDuring construction or repair, it is often the case that you need a clinometer. Despite the fact that this is a really useful tool, it is not in the arsenal of every person. For you to have an alternative, we suggest you install the iLevel application on your smartphone.

Here you get a completely redesigned virtual clinometer, which will help you check the surface alignment, as well as to measure angles.

The accuracy of iLevel calculations is 0.1 degrees – you have to admit, this figure is not always obtained even in real life. For dark places and rooms, you can even use a built-in flashlight.

For convenience, there is an acoustic signal and feedback that informs you about the size of the angle or the difference between the actual and the given angle. If you need to place something at a certain angle, you will enter the values in the application yourself and you can start setting up.

In addition to a clinometer, you also have the option to measure distance or dimensions in inches and centimeters. iLevel is a good all-round tool.



Clinometer by PixelProse SARL

clinometerThe most functional applications usually have a fairly simple design and functionality. Clinometer is the easiest and lightest visual application – you get accurate measurements with no extra effort.

Clinometer can measure both the inclination of objects as well as deviations that you want to know. Two metrics – roll and pitch – are used to calculate the indicators, so you can refine all the data.

In addition to measuring angles, you can measure how flat the surface is, as well as the slope of the floor or objects. To measure the inclination on either side, you will first need to rotate the phone around an axis perpendicular to the screen.

So your smartphone with Clinometer will be able to measure the slope. However, if you want to measure the pitch of an angle, you can use a special measurement to get a pitch close to zero. This is a good measurement that allows you to get accurate data when measuring from height or with a camera.

Smart Protractor

smart protractorSmart Tools has already released many excellent products that help people in a variety of cases and areas. For example, they include virtual rulers, automatic room planners, and much more.

As you understand, the developers have created another useful application – Smart Protractor. It is one of several parts of the application, which is designed to measure angles, tilts, and deviations.

This application includes 2 basic tools to help you find out if the surface is really uneven and what angle your roof is. In touch mode, you will need to attach an object to your smartphone screen, where you can use the virtual protractor to measure the angle yourself visually.

In the second mode, you will need to use the weight and vertical lines – it is mainly used for the slope. Most importantly, this application has absolutely no advertising, as well as you can change the units of measurement as you need it.
