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.

Tone Generator: Frequency Hz plays audio tones from 1 Hz to 22 kHz — pick a frequency or a preset, press the big Play button under the dial, and hear it. Sine, square, sawtooth and triangle waves, plus white, pink and brown noise. The tone keeps playing when you switch to another app or lock the screen, so a tone or noise can run while you read, work or rest. A sleep timer (15, 30 or 60 minutes) stops it for you. ▶ SET THE FREQUENCY • Step with the frequency arrows, jump by semitone or octave, or tap A4 • Watch the note name and cents readout as you go • Type exact Hz values for the right ear, the mixer and the sweep • The tone you hear matches the frequency shown on screen ▶ WAVEFORMS AND NOISE • Sine for a clean pure tone • Square, sawtooth and triangle for harmonics • White, pink and brown noise ▶ PRESETS — ONE TAP TO HEAR THEM • Tinnitus masking tone, sleep, A4 440 Hz, subwoofer 60 Hz, bass strings E A D G, dog whistle, cat repel • Brainwave beat pack (delta, theta, alpha, beta, gamma) and solfeggio tones • Save your own presets, including mixer setups • Tapping a preset starts the sound; if a tone is already playing, it switches to the new preset ▶ CHANNELS, BEATS AND SWEEP • Mono, stereo with a separate right-ear frequency, binaural beats and isochronic tones • Dual tone: two frequencies at once • Mixer: layer up to four tones, each with its own waveform and level • Frequency sweep between any two frequencies, once or looping, with the dial following the sweep ▶ MORE TOOLS • Instrument tuner: play a note and see its pitch and cents (uses the microphone) • Water Eject: a 165 Hz tone at full volume to help push water out of the speaker • Speaker and subwoofer checks with steady tones and sweeps ▶ WHO IT IS FOR • Musicians checking tuning against an exact Hz • People testing speakers, headphones and subwoofers • Students exploring sound, frequency and waveforms • Anyone who wants a steady tone or noise in the background ▶ SAFETY Start at a low volume. Loud tones, especially high frequencies, can harm hearing and speakers. Brainwave and solfeggio presets are traditionally used in relaxation and focus routines; they are not a medical or therapeutic treatment. The tinnitus preset is a masking tone, not a treatment. Available in 30 languages.
