Very nice app. Would it be possible to add in the log the tilt angles (x,y,z axis with true vertical axis angles::alpha, beta, gamma), the position lat,long,alt and the azimuth (Y component axis with true north). I think the data is there in other apps but it would be nice to be able to have everything in one log for some simple component rotation to the radial-transveral system. It would enable some quick direction finding for the source of some events.

Hi, thanks for your suggestions - yes I think I could add those things in fairly easily.

(Sorry for the late response - I have not been so active with the Jolla lately, and the openrepos notification of your message was flagged as spam - I just came across it now).

Thanks, it's good to know it's not too much pain to do it.

Getting greedy here (for what is worth) and asking if the microphone can be added as well with an equivalent sampling rate (PP, PS, SP and SS wave tracking). Guess that Jolla should have published somewhere the mV/mbar or mV/Pa conversion factor for their microphone. There is already an app that does dB readings (SailDBMeter I think but that is in dB). Would make a nice 'amateur' single channel multicomponent seismic aquisition system. (P,X,Y,Z)

So I got back into Quakefish - this update (1.2) was just me finishing off some UI changes that I began a long time ago; additional logger output is next.

Excellent. However this is a seismoscope. Would be great to have (a) scales (m/s² + timeline) on the graphs (b) an option to record measurements (c) landscape display with X, Y & Z in one graph in three colors.

Thanks; all of your suggestions are noted.
