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
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.

Response from developer
Please make sure that location services are enabled for the app. Also, feel free to modify the data in the CSV file to units of your liking.
Good
Interested in the magnetometer more than the rest. Seems to be quite accurate apart from the Y axis. This has a scaling problem. Worth 4 stars.
No Lat/Long in output file
Useless DataCollection without positional lat long!!!
Response from developer
Please make sure that location services are enabled for the app.
Sample rate to high
App has potential but the sample rate is too high, will produce large amount of data. Need to be able to select a sample rate of say once a minute to once an hour to get a sensible data quantity in a day to see trends.
No Data File
This app does not email the data file nor put it in iTunes using iOS 8. I have an old phone still using iOS7 and had no problem. In addition, the developer has disappeared along with his data file. Other than that, the app is exactly what I wanted.
Response from developer
Please make sure your phone is configured with a Mail account in order to email the CSV file.
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!
Wrong results
The magnetometer data is wrong compare to three other apps I used.
Perfect
It's good to see the numbers behind the sensors. The potential uses are amazing.
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.
Great!
Really like fiddling around with this app.
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.

Please
Please add a way to "tare" the orientation of the iPhone 5.
For instance camera points magnetic north and you activate "tare". The system then locks in on that heading and attitude.

Great product!
Please include option of filters and graphs for use DC in applications.
Thank you Chris.
Thank you Chris.
Impressive advancements!
I worked military inertial guidance systems in the '90s with the smallest systems being the size of a small suitcase. This iPAD includes almost all the components needed for inertial guidance!
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.

Perfect for what I needed
I was able to test some Matlab code using this app. Helped me get a tough project done on time. Good app with straightforward output. I wish there was a way to read the data in real time from a computer. Maybe over Bluetooth? That would be amazing. Still, a nice app that does what it needs to.
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
Angles not working
This is great app although my angles are not showing any reading .
Agree with previous
Default sampling rate leads to big files that require post processing
