The app helps hot tub, spa, and pool owners calculate chemical doses for calcium, alkalinity, pH, sanitizer, and stabilizer. It also includes a water balancing feature to calculate the Langelier Saturation Index for system maintenance.
Calculate loss in transmission systems by selecting type, pipe material, and dimensions. Input pipe schedule and size to determine energy loss. Compare initial and operational costs for optimal pipe selection.
Calculate rafter, hip, and jack rafter lengths with precise angle cuts and birdsmouth dimensions. Input roof dimensions for instant results. Guide users in cutting roof components accurately without trial and error.
Calculate sawing angles for mitre or sliding compound mitre saws. Input beam inclination and number of beams to determine workpiece alignment. Display result field turns green upon calculation completion.
Measure tilt angles using device motion. Access a , surface , and camera features. Large buttons improve visibility. Flashlight enables use in low-light conditions.
Use camera to measure length, area, angle, or height of objects in real-world environment. Draw objects on surfaces and visualize measurements in augmented reality.
The app calculates unknown angles and sides of non-right-angled triangles. It shows the steps used for calculations, allowing users to understand the Sine and Cosine rules.
