# GENERATE ANY TONE, FROM 1 HZ TO 40 KHZ Frequency is a tone generator. Set a pitch by hertz or by note and octave, choose a waveform, and play it. It also plays the low sweep that pushes water out of a blocked speaker. # PLAY A TONE AT ANY FREQUENCY Enter a value in hertz, or pick a note and an octave and let the app work it out. The range runs from 1 Hz to 40,000 Hz, past the top of human hearing. # CHOOSE YOUR WAVEFORM Sine, triangle, sawtooth, and square. Each has its own character, and switching between them at the same pitch is the quickest way to hear the difference. # PLAY SEVERAL TONES AT ONCE Run more than one tone together, each with its own frequency, waveform, and volume, and listen to how they interact. # CLEAN YOUR SPEAKER Water trapped in a speaker muffles it. Playing a low-frequency tone at full volume vibrates the driver and pushes the water out — the same technique a smartwatch uses to eject water after a swim. # A REFERENCE PITCH TO TUNE AGAINST Play a note at a known frequency and tune your instrument to it by ear. Frequency plays the reference; it does not listen, so nothing you play reaches the app. # TUTORIALS INCLUDED Step-by-step guides for generating tones, working with waveforms, running several at once, and cleaning a speaker. # SUBSCRIPTIONS AND AUTOMATIC RENEWAL - Your subscription includes access to the features listed above. - Payment will be charged to your Apple ID Account at confirmation of purchase. - Subscription automatically renews unless auto-renewal is turned off at least 24 hours before the end of the current period. - Your account will be charged for renewal within 24 hours prior to the end of your selected subscription period. - Subscriptions can be managed and auto-renewal turned off in your App Store Account Settings. # LEGAL Terms of Service: https://cooptimizeit.com/terms-of-service Privacy Policy: https://cooptimizeit.com/privacy-policy # SUPPORT Contact us at info@cooptimizeit.com.

Verdict
The clearest difference is rating: Frequency at 3.9 against Granula Synth's 1.8. Frequency also leads on update cadence (every 10 days vs every 25 months) and ratings volume (24 vs 4). Granula Synth's advantage is review sentiment (20% vs 0%) and iOS requirement (12.0 vs 16.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Granula Synth sells 3 in-app purchases, starting at $2.99 per month and Frequency sells 9 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Frequency holds the better App Store score, 3.9 against 1.8. That said, the two scores are not equally well evidenced: Frequency has 24 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 20% of Granula Synth's written reviews are positive against 0% of Frequency's, so the app with the better star average is not the one people write more warmly about.
Granula Synth ships an update every 25 months, Frequency every 10 days. The most recent releases landed on October 18, 2026 and October 24, 2026 respectively.
