Frequency vs PhaseXpert

# 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.

PhaseXpert is an engineering application for calculating thermodynamic and transport properties of CO₂ and supported CO₂-rich mixtures. Designed for engineers, researchers and professionals working with carbon capture, transport and storage, PhaseXpert combines practical calculation tools with transparent scientific traceability. With PhaseXpert you can: - Calculate density, viscosity, molar mass, specific volume, compressibility factor and other supported properties. - Define custom CO₂-rich mixtures using common impurities such as N₂, O₂, Ar, CH₄, H₂, CO, H₂S and H₂O. - Explore phase behaviour and phase diagrams. - Save and reuse calculation cases. - Access built-in representative CCS compositions. - Compare multiple cases side by side. - Run property sweeps across pressure and temperature ranges. - Export calculation results for further analysis and documentation. - See when a property and operating state are supported by independent experimental validation evidence. - Explore validated reference cases directly from the Saved Cases section. PhaseXpert clearly separates calculation from validation. General Properties provides the primary engineering calculations, while the Validation layer identifies specific compositions, properties and operating ranges for which independent experimental evidence is available. The app also provides information about the IFE Model, a proprietary thermodynamic model currently under development by IFE Flow Technology and supported by experimental work, including measurements in IFE’s FALCON CO₂ facility. PhaseXpert includes English and Norwegian interfaces and is designed for practical engineering use on iPhone. Important: PhaseXpert is an engineering support tool. Users remain responsible for verifying results and determining their suitability for safety-critical, design, regulatory or commercial applications.
