Laser level (leveling instrument) is an excellent measurement app equipped with: laser pointer, regular 3-mode spirit level / bubble level (libella) and clinometer (inclinometer) for measuring vertical angles and determining the exact horizontal plane. It's perfect, handy and precise bubble level tool for every handyman. Main modes of this laser level: - innovative laser leveling / laser pointer - using built-in sensors (gyroscope and accelerometer), camera and extended / augmented reality, helps you to determine the vertical and horizontal levels around you, - regular spirit level (bubble level, libella) - works like a traditional bubble level tool, place your smartphone or tablet, on the surface or on the object to be measured or set at any angle, - clinometer, also called an inclinometer, is primarily used to measure vertical angles and to determine the angle of inclination of any object from the vertical determined by the gravitational force. These modes are equipped in precision digital and analog indicators. Data are presented in degrees and percentages and any different units which you choose. Additional features, you can: - calibrate level of your device, - adjust the precision of measurement, - read data in different units, - lock the orientation, - take pictures while measuring and you can send measurement results to anyone, - this app does not require internet access. Sample applications: - you can measure the angle or inclination of any objects (including distant), such as roof, buildings, columns, mountains, trees, etc. - you can set any angle of inclination of the surface and the level of home installed appliances, devices, such as: install a refrigerator, washing machine or hang a shelf, painting etc. - suitable for repair and construction work, you can use it as a digital measuring tape or laser measuring tape, - useful for interior design, exterior works, in house and in garden, - many others.

This application allows you to help in checking the existing and planning future isolation. After entering data on the temperature and humidity of the air and selecting all layers of the enclosing structure (starting from inside the building and ending with the exterior trim of the facade or roof) in the Thermal Transmittance Calc, you will receive information on all likely heat losses, as well as possible problems with humidity. A schedule will be built, according to which you can track how the temperature and humidity will change and where the dew point in the layers of the structure will be. - Easy to use, enter all the data and immediately get the results. - Ability to enter the temperature in both Celsius and Fahrenheit. - Ability to enter the size of the layer in centimeters and inches.

ReceptionRating · Positive reviews · Number of ratings

Pocket Laser Level holds the better App Store score, 4.7 against 4.1. That said, the two scores are not equally well evidenced: Pocket Laser Level has 264 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 58% of Pocket Laser Level's written reviews are positive against 75% of Thermal Transmittance Calc's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Pocket Laser Level ships an update every 10 months, Thermal Transmittance Calc every 11 months. The most recent releases landed on November 11, 2026 and November 6, 2026 respectively.
