# 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 call

The clearest difference is price: Frequency at Free against BoxMaster's $2.99. Frequency also leads on update cadence (every 10 days vs every 4 weeks) and iOS requirement (16.0 vs 18.0). BoxMaster's advantage is in-app purchases (none vs 10). On ads and device support there is nothing between them.
