Nice app. Unfortunately it appears that there are issues with the MPL / Orientation: 1. Does not work if the update rate is "too" large (>= 0.5 sec. ?) 2. Large deviation of single values from mean, e.g. 50.2, 50.0, 50.0, !!45.0!!, 50.5, 50.0, 50.4, ... Std deviation seems to be too large too. Does not happen with other similar sensors / compass apps (at same update rate). Also, 'Recording Interval' value changes on edit.
Accelerometer data freezes I used this app to collect accelerometer data, and I think this is quite good except freezes. I set the frequency to 20hz (0.05 sec), and a taller guy was asked to carry the smartphone to collect accelerometer data. But the data stored while he was walking had same x,y, and z values for some time. It might be caused by some extreme values or the cheap ($40) smartphone, I guess. So I am not sure I can use this for my research and trying to figure out what the exact problem is.
Too hard to calibrate? up until now i had a habbit of not writing bad revews. I always appreciate the effort. This time i felt obliged to write. As you must know, android microphones are built for human voice. In order for your app to be as accurate as possible, you must calibrate your tool accordingly. I was honestly insulted to be represented with partial work, especially where it matters, treating us as morans.
Convenient display of a the various sensors. I noted while experimenting though that on my device the ambient temperature and battery temperature are showing early the same value and that battery values do not seen to output to CSV.
Great app, awful icon! You guys are actually bragging about the new icon? Why? It looks cartoonish....childish. Your app has been a fantastic supplement to modern PDA phones. Now I have to use my launcher icon packs to change the icon.
Great app!! One question Is there a way to record when the GPS data is updated? I want to collect data from accel gyro and gps/I know I can set sampling to about 100 hz for the accel and gyro, but GPS only updates at 1 hz. If I set app to sample at 100 hz, is it possible to know when the app is showing a new sample from GPS?
