Hertz in CM vs PivotClock

This is a kind of unique dual calculator that gives you the distance (wavelength) in CM (centimeters) according to the selected frequency in Hertz or vice versa. All in relation to the property of the medium (CM/SEC). 34300 is chosen as an average speed of sound in air. 148100 is a good suggestion in water. It might be 'useful' for some people to have a stand-alone app for doing just this. To see more apps like this, go to www.discobajas.com

PivotClock is a clock app that lets you freely rotate the display to any angle - and lock it there. Unlike your phone's auto-rotation, PivotClock works independently. Set it to 0, 90, 180, 270 degrees, or any custom angle. Once locked, the clock stays exactly where you need it. FEATURES - Free Rotation Rotate the clock to any angle using the intuitive dial editor. Drag to rotate, release to snap - just like editing a photo. - Quick Presets One tap to snap to 0 / 90 / 180 / 270 degrees. Perfect for landscape bedside or upside-down mounting. - Digital and Analog Switch between a clean digital display and a classic analog face. Seconds, date, and 12/24-hour format all configurable. - 4 Themes Minimal, Bold, Retro (green glow), and Soft - each with 5 accent color options. - OLED-Optimized Pure black background saves battery on OLED screens. Burn-in protection slowly drifts the display so no pixel stays static. - Ultra Dim Mode Swipe up/down to darken the screen beyond the system minimum - ideal for bedrooms at night. - HUD Mirror Mode Horizontal flip for windshield projection or reverse-mounted displays. - Screen Always On The screen stays on as long as PivotClock is open. PERFECT FOR - Bedside clock - lay your phone flat or prop it at any angle - Desk clock - portrait, landscape, or anything between - Car mount - rotate to match your dashboard angle - Overhead mount - 180 degree flip when phone is upside down - HUD mode - mirror the display onto your windshield
