    It would be great to see the "average over a few seconds" and a "peak hold" function

    Great little App and worth the 69p to remove the adds alone from the free version.

    Would still like to see the ability to zoom in on frequency ranges for better accuracy still. And a curve tracing capability to allow analysis of room characteristics through playing a frequency sweep.

    Running on Galaxy S4. Really fast and precise and does the job of devices costing 100's (if not 1000's) of £££'s. One addition that would be amazing would be a feature to zoom in on a desired frequency range for clarity. E.g. between 10 and 100hz.
