Tone generator vs Universal Toolbox

Generate various periodic signals with different waveforms with adjustable frequency and amplitude. These are used to test electronic circuits such as amplifiers and filters. Also suitable for musicians to tune their instruments. As soon as a note sounds, the integrated tuner recognizes the pitch and displays the note name and deviation. For any instrument that produces an even tone. A metronome also helps you to practise. Drive insects away or compare your hearing ability with your friends and relatives and share your results! Or watch others straining their ears to find the sounds that cannot locate you. Party fun is guaranteed! optional features (Purchase): - free of Ads - manual frequency input - support app functionality for connected Bluetooth devices, e.g. speaker - different signals - white/pink noise - tuner for tuning instruments (real-time tone recognition C1-C8) with tuning whistle - metronome for a steady tempo - note/tone for frequency - Left/right channel, stereo - create a tone sequence for playing several different frequencies in particular time slot - loop for tone sequence - save and delete tone sequences - load saved tone sequences - send your tone sequence as an audio file (.caf format) - option to compress audio files Attention: If you want to share your results with others, first test your audible frequencies, then mark under the speakers your lowest audible tone and your highest audible tone (stored only temporarily). A small hint: the chart will show you what other frequencies of your age are still possible to reach.

Universal Toolbox brings practical measurement, sensor, scanning and everyday calculation tools together in one organized app. MEASURE AND OBSERVE - Level & Angle shows live X/Y angles, inclination and a responsive bubble with explicit calibration. - Compass provides heading, bearing lock, coordinates and available altitude information. - Motion Sensors displays acceleration, rotation rate, gravity and device attitude. - Barometer shows atmospheric pressure and relative altitude when supported by the device. - Noise Meter displays raw audio levels and clearly labeled estimated or calibrated sound-pressure readings. - Screen Ruler offers metric and fractional-inch scales with per-device calibration. SCAN AND CREATE - Scan QR codes and common barcode formats using the camera. - Review detected content before opening a link or taking another action. - Generate, copy and share QR codes and Code 128 barcodes on your device. EVERYDAY UTILITIES - Control flashlight brightness and use Steady, Strobe or SOS patterns. - Convert length, mass, temperature, volume, area, speed, pressure, energy and time units. - Use a Decimal-based calculator with percentages, repeated operations and copy support. PRIVACY AND ACCESS Hardware readings and generated content are processed on your device. Camera, microphone, motion and location access are requested only when you open a tool that needs them. No account is required. Five core tools are available for free. Premium unlocks the remaining Premium tools and removes eligible advertising.
