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.

Tuning Fork is a tool for tone generation, instrument playback, and sound observation. Build a sound from a familiar reference pitch, then explore it through live waveforms and spectra. Customize frequency, output gain, and harmonic components. Choose sine, square, triangle, or sawtooth waves, layer harmonics, and save configurations for later use. Play notes on a piano keyboard with the included GeneralUser GS soundfont. With microphone permission, the analyzer shows a live waveform, frequency reading, input level, and spectrum on your device. Core instrument playback, custom frequency, basic waveforms, and sound analysis are free. Pro adds the complete instrument library, more waveforms, unlimited sound configurations, and longer audio exports. Prices and availability are shown in the App Store. The app does not collect your data. Microphone input is processed on-device for live analysis and is not uploaded to developer servers.

Verdict

The call

The clearest difference is rating: Tuning Fork Studio at 5.0 against Tone generator's 4.0. Tuning Fork Studio also leads on ads (none vs shown) and update cadence (every 3 months vs every 5 months). Tone generator's advantage is ratings volume (152 vs 1) and iOS requirement (12.0 vs 15.0). On price, in-app purchases, monetization model and device support there is nothing between them.
