Description
This app was developed for researchers so that they may capture accelerometer, gyroscope, and magnetometer data directly from their iOS device to use for research or play around with. The data is time stamped and the data from Apple's enhanced device motion is included for reference.

Fixed the issue with older devices thinking they were sampling at 120 Hz.
Changes the outputted data format to:
ATTITUDE 14.415556 30.297359 -3.455386 -83.958420
ACCEL 14.416474 -0.031647 -0.520920 -0.858597
GYRO 14.417261 0.197838 0.169969 -0.149532
MAGNETO 14.417634 -211.078125 231.325775 -340.823425
Where the first column is the sensor, the second is the timestamp, and the following three the sensors values in that axis.
Accelerometer/Magnetometer is ordered as x, y, and z axis.
Gyroscope is ordered as p, q, and r axis.
Attitude is ordered as pitch, roll, and yaw.

Amazing Potential
As a recording mechanism, this app has some incredible potential. It could really benefit, however, by offering the user a way to adjust the sampling rate (i.e., takes a reading every 15 milliseconds or 2 seconds or 9 minutes). Otherwise, the saved file just ends up being huge. That would easily make this a 4 or 5-star app!
sd9320,
App is not functional
Purchased app for a dollar then realized it doesn’t work. I cannot click the record button or anything else in the app. Waste of money
Rouelf,
Says it collect data, but delivers something a little different
1) App Does not seem to show up in Settings.
2) App is not collecting GPS data.
3) App output CVS data has unnecessary data:
Want as follows:
Timestamp, Accel_X, Accel_Y, Accel_Z, Gyro_X, Gyro_Y, Gyro_Z, Mag_X, Mag_Y, Mag_Z, Lat, Long
Gyro should be rads/sec.

Lumberton NJ,
No Lat/Long in output file
Useless DataCollection without positional lat long!!!
Herschel the inertial,
Not sure about emailing - resolved
Recorded five seconds at one hertz.
Display does not change when recording (maybe that is ok.)
Update: this is expected behavior.
When prompted after end of recording I selected 'email' and then app 'disappeared.' On restart, app is back to normal. I do not use apple email but another well-known third-party app.
Update: EBKAC ... I had not enabled the email setting for the ipad. Once I pointed it to my third-party app, everything worked just fine.
I have not checked via iTunes to see if data was actually recorded.
Update: the data was recorded and sent out via email.
Use was on ipad mini.
Cool app. Hope this helps.
Update: still a cool app. Hope my mistakes help some other user.

Data collection
What are the units for the magnetometer? There seem to be large offsets (200) in the mag data obvious when I spin the iPhone which I don't see with other asp. Some evidence of gain mismatch between axes also. Maybe this is raw sensor data? A scroll chart (similar to the icon) would be a great addition.
PoloniumMan,
Geeky fun app
This is a fun way to exploit the sensor information in my iPhone. The latest update increased the sampling rate to 500 Hz; however, the magnetometer appears to be off by a decimal point. The x,y,z components are hundreds of uT where it should be tens of uT.
Lushrrrr,
Will you share?
I found this when I searched the app store for Kalman. Are you implementing a KF? Is Apple? Can we talk? You can reach me at lusher00atgmaildotcom
Sud213,
You Made my day
Man, i suggest you to use the same export format of pocket imu app. It's easier to process with a spreadsheet and to produce graph for engineering paper! You have no idea how important is this app!
doctorgoldny,
Great product!
Please include option of filters and graphs for use DC in applications.
Thank you Chris.
Thank you Chris.
