Lambda vs Camera Measure

Musicians and Sound Engineers. Musical Notes and Frequencies and Wavelengths. Now there's an app from dgApps to convert between them all. The app features a sliding fader to dynamically change frequency, wavelength and musical note, with locks to step through standard third octave frequencies or whole musical notes. There's a built in oscillator so you can hear the frequency, and a frequency tracker so the app can tell you the frequency. Both the oscillator and the frequency tracker display the audio waveform. A settings section allows for different tuning standards, and variations in the speed of sound. Lambda can also receive calculated Speed of Sound in Air values from another dgApps app, Cair. Lambda is now a universal app, equally at home on an iPhone as on an iPad. In Split Mode on an iPad device, side by side with Cair, the calculated Speed of Sound in Air is passed in real time to the Lambda app. Lambda allows you to share frequency/wavelength/note data via all the usual sharing methods.

MEASURE DISTANCE AND OBJECTS WITH YOUR CAMERA – FAST, ACCURATE AND CONTACT-FREE Turn your iPhone into a powerful camera ruler, tape measure, and precision measurement tool. Measure distance, length, angles, areas, and circles directly from photos - no physical tools required. Stop guessing. Get accurate measurements in seconds. Simply place a reference object such as a credit card or sheet of paper, take a photo, and start measuring instantly. PRECISION MEASUREMENT FOR EVERY SITUATION From everyday tasks to professional use, measure anything from large outdoor objects to very small details with high accuracy. • Measure distance and object size from photos • Works for both large-scale and fine measurements • Accurate down to sub-millimeter precision depending on conditions SMART MEASUREMENT WITH REFERENCE OBJECTS Use common items to calibrate your measurements: • Credit card • A4 or Letter paper • CD or DVD • Coins • Any custom object with known size Measure large, small, distant, or hard-to-reach objects without contact. MEASUREMENT MODES Length Mode
Measure distance and object size in any direction and compare multiple objects. Angle Mode
Measure angles, slopes, and lengths using dual rulers. As well as for large objects that do not fit on the screen. Area Mode / Freehand Drawing
Calculate the area of irregular shapes using intuitive freehand tracing. Circle Mode
Measure radius, diameter, circumference, and area of circular objects. As well as for large objects that don't fit entirely in the photo. ADVANCED FEATURES • Measure from saved photos • Import and measure images from your gallery • Zoom and edit tools for precise alignment • Supports meters, centimeters, millimeters, inches, um and nm • Relative measurements based on reference objects • Works with high-resolution and scientific images • Suitable for detailed and technical measurement tasks HOW IT WORKS Step 1: Place a reference object in the same plane as the object you want to measure
 Step 2: Take a photo
 Step 3: Align the measurement tools using zoom and editing for precise results REAL-LIFE USE CASES • Measure objects and distances on scaled plans • Check baggage dimensions • DIY, woodworking, and crafting projects • Measure large outdoor objects such as houses or trees • Compare height of people • Measure fabric, cloth, and surface areas • Measure objects from photos, including fish or previous catches • Measure mechanical parts such as bolts, nuts, and bearings • Use as an angle finder or pitch gauge • Measure small objects such as jewelry, screws, and insects • Analyze X-ray images with a reference WHY CHOOSE THIS APP • Replaces ruler, tape measure, and area calculator • Measure anytime using only your phone and camera • Works for both quick everyday tasks and professional applications • Ease of use
