Unreliable speed meter Well, it does log the accelerometer as it should. But the "acc integration" feature is useless, probably due to high jitter and inaccuracy of my galaxy note n7000 acc meter. After proper init, this app shows speed increase to 10kmh when phone is lying on a metro chair while the train is standing on the station. Speed increases when train is braking on the station. Useless.
Lacks 1. I expected to see the magnitude of the acceleration, as I am not very good in calculating square roots in my head in real time. 2. The colors are confusing. All the computer graphics world uses RGB for XYZ respectively, not for YZX. 3. Happens I need to buy the app to export the data. 4. Does not record data when the screen is turned off.
Couch will get speeding fine Testing the app by laying it flat on my couch and noticed it consistent accelerating. I stopped it when it reached 100km/h. The notes above advised the data is unreliable but there was instant and sustained acceleration as soon as app was started.
John Pretty neat.epecicially like color scheme of waveform and sensitivity is great.one app I had was too sensitive and entire display jumped.have similar waveform app for sound effect and audio wave analysis.This I recommend.just remember,this measures accelrative movement,not a speed indicator
Nice no nonsense app. Really functional well built app. Be good if you could use accelerometer function to measure short distances as a virtual ruler.
Nice little app, some problems The graph is confusing. The Y, X and Z values seem to be interrelated with the pitch and roll perhaps some explication would clarify, and i just do not understand. I would have thought X, Y and Z would be the acceleration in each vector, but, tilting the device and holding it in position yields values > 0 related to the angle of the tilt. I have not tried the speedometer.
- fix: application refused to launch on most tablets and some other devices with crash
