Find studs, check levels, measure angles
Detect metal objects in walls using five presets for different materials. Receive real-time feedback via visual, sound, and haptic alerts. Measure angles and check levels with an accurate bubble level. Includes magnetic for precise detection.
Measure levels in lux, foot-candle, or color temperature (CCT) in Kelvin. Use the device's camera as a sensor. View readings in real time. Save and share measurements. No ads. Simple and accurate interface.
Capture and annotate object photos with dimensions, arrows, and angles. Add text comments for clarity. Share annotated images for better understanding. Store and retrieve measurements for future reference.
The app allows users to photograph or import images to record measurements, angles, and text notes. Users can save and share these annotated images, organizing them into folders.
The app provides an interactive unit circle to explore relations between angles and trigonometric ratios. It includes an exact trigonometric ratios table and a handbook of trigonometric formulas.
Calculate measurements and perform unit conversions for projects. Perform trigonometric calculations and angle measurements. Access a full user guide and use built-in formulas for precise calculations.
Capture photos of objects and add measurements with arrows and angles. Include detailed images and text comments for clarity. Store and share annotated sketches for better understanding among collaborators.
Measure angles, level surfaces, and track progress
Measure angles and slopes with the protractor tool. Use the level function to check horizontal, vertical, and 45° angles. Measure height, length, and width with the caliper tool.
Measure levels in decibels using the device’s microphone. Display real-time audio frequency and dB readings. Apply filters for specific frequency and dB ranges. Share measurements via Messages, Email, WhatsApp, Notes, and other apps.
Solve triangles with two modes. Regular triangle mode allows input of 2 sides and an angle, 2 angles and a side, or 3 sides. Right triangle mode accepts 2 sides or a side and an angle. Calculates missing values based on input.
Measure sound levels using iPhone's microphone. Display readings in real time. Log noise data and view historical trends. Set custom volume alerts. Share measurements via email or social media.
Convert device into a versatile finder for quick measurements. Measure degrees and angles for high or low- tasks. Use protractor and finder tools for accurate readings. Sync with device sensors for real-time feedback.
Dimensions, spacing, and angles in screenshots and photos. Analyze color values, grid alignment, and element positions. Export measurements and compare dimensions across images.
Measure tilt angles from 0 to 359 degrees. Display in degrees, percentage, and sum angles for 180 or 360 degrees. Switch to theodolite mode and set specified angles to 0 degrees.
Measure lengths with a ruler supporting metric and imperial units. Detect ambient noise levels using a decibel meter. Use a protractor tool to measure angles via the camera. Calibrate screens for accurate color display.
Control and monitor 2-axis digital levels via Bluetooth. Perform simultaneous levelling and angle measurement. Conduct 2D alignment tasks remotely. Adjust settings and view real-time data on the mobile device.
