The app offers practice in addition, subtraction, multiplication, division, and angles. Users can track their progress with statistics and choose between Study Mode, Stress Test, or a 20-question Quiz.
Measure size with a smartphone camera using guided steps. Select from US, UK, or EU sizing standards. Save previous measurements for future reference. Share results directly with retailers or jewelers.
Convert units across 180+ categories including angles, areas, cooking units, weight, clothing, and shoes. Convert 180+ currencies and digital currencies like Bitcoin and Doge. Enter values and get instant conversion results.
Measure objects by taking a photo with a smartphone or tablet. Capture real-time dimensions like height, width, area, and length. Share measurements via Cloud. Sync with laser device for accurate data. Export measurements in various formats.
This app calculates unknown angles and sides of right-angled triangles. It can draw a scale drawing of the triangle and provides a formula sheet for manual calculations.
Calculate dimensions and properties of 2D and 3D shapes. Input measurements to determine area, volume, surface area, and perimeter. View interactive 3D models of solids like cube, sphere, and cylinder. Switch between 2D and 3D views for each shape.
The app designs four-bar linkages connecting input and output crank rotations. Users define crank locations and angles, and the app generates the linkage design.
Measure intensity with built-in phone sensors or Bluetooth-connected UNI-T UT383 BT sensor. Display values in lux and micromoles. Track exposure over time. Save and export measurement data. Set level alerts.
Distances with a 5-meter by aligning the phone on a surface and sliding it for accurate readings. Use mode to small objects by placing the phone between them and viewing the result. Save and share measurement data directly.
Measure ambient instantly with live EV feedback. Adjust aperture, shutter speed, and ISO for accurate exposure. Save and compare readings over time. Sync measurements with other devices for consistent results.
Measure with real-time readings and +/- 1 dB accuracy. Log and analyze noise data over time. Set custom thresholds and receive alerts. Export measurement logs in various formats. Sync data with cloud storage for long-term tracking.
Access RV types, classes, and system diagrams for electrical, plumbing, and appliance setups. Includes calculators for weight, leveling, and towing calculations.
The app displays a vehicle's pitch and roll angles in real-time. It offers adjustable alarms for tip-over warnings and supports both portrait and horizontal orientations.
