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.
How do I calibrate my accelerometer. I want mine to be reset cuz my phone accelerometer is not responding. When I play games my screen just keeps turning landscape and reverse landscape. This is very annoying. Plzzz help me and I will rate you five stars (Samsung galaxy core)
Best IMU/GPS logger After much searching, I found this app, which meets all of my needs for logging sensor data. The only downside (sort of nitpicking ) is that there is not separate time stamp for GPS, which has a unique timing from the IMU. This causes some issues with taking derivatives.
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.
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.
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.

- Awesome new icon thanks to David from DRS Soft.
- Fast recording: small visual and stability improvements.

- A few minor bugfixes.
As always, a more detailed changelog and extra info available in website
