AcoustiQ
Read full descriptionHide full description
With acoust IQ, sound level measurements can be performed using an iPhone or iPad in combination with a Class 1 microphone. The app supports the entire measurement process – from data collection and integration of metadata to documentation. All relevant information such as images, text, or GPS data can be captured directly during the measurement and linked to the results. The data can then be edited, analyzed, and exported as a report based on templates. The app is aimed at technically experienced users who want to carry out sound measurements easily, reliably, and with minimal effort. The full functionality is only available with a subscription. For subscriptions the standard Apple Terms of Use (EULA) are applicable,(https://www.apple.com/legal/internet-services/itunes/dev/stdeula/). Note: To perform a Class 1 measurement, a suitable microphone is required. We currently support the Microtech Gefell MV240/MKS225. For Class 2 measurements, the UMIK-2 (miniDSP) microphone is supported. Since the internal microphone cannot be calibrated, measurements are only possible with limitations. More microphones will be supported in a future release.

Verdict
The clearest difference is in-app purchases: HEAD B2U at none against AcoustiQ's 2. HEAD B2U also leads on iOS requirement (15.0 vs 17.0). AcoustiQ's advantage is update cadence (monthly vs every 10 months). On price, ads and device support there is nothing between them.
