M11-M33
on the record data (csv file), what does m11, m12,m13 actually mean?
Response from developer
Hello, these values represent the rotation matrix of the device, see this for more info: https://developer.apple.com/documentation/coremotion/cmattitude/1616139-rotationmatrix Thanks for your support.
Works as adevertized
This was the only app I found to easy capture the telemetry data I was looking for. I tried several other app export data was challenging, logs were in accurate. I have two suggestion, the app needs some documentation, specifically what all the data headers are. When I airdrop the data and open I in excel and there are tons on columns some of which I donβt know what they are.

Great App!!!
Iβve used several sensor apps on iPhone, and this is my favorite. I like the intuitive interface and the ability to record for long periods. Iβve used it in many applications, including precision analysis of aircraft motion during test flights.

Thanks for the great review, so glad to hear how useful Sensor Play is out there.
Good but not perfect.
Works great on my iPhone 11 except for the following that I have found so far.
I set it to record for 45,000 seconds (750 minutes or 12.5 hours) and it shuts off at 6:00 hours.
Also, I set the multi sensor recording to trigger on a g level and it only triggers on -g levels on the 2 g scale. I flew my iPhone 11 on a Blue Origin flight and found this out the hard way.

Very Good but not complete !!
1) CMCalibratedMagnetic Field x, y, z are always zero (0), on iPhone 8+ and my iPad.
2) Though CMMagnetometer values are useful for somethings, CLHeadingComponent Values x, y, z (micro Tesla), are better for calculating stuff, IMHO,
CLHeading:
I believe, Represents a vector pointing to magnetic North.
Please fix, and add CLHeading Magnetic Data π€π.

The best sensor data recorder!
Great and easy to use app for engineers, students, researchers and anyone obsessed with motion analysis!
I wish it worked with the screen locked and it could record the real-time location. (Perhaps it does, but couldn't figure out how)

Thanks for the great review. Sensor Play will record in the background plus record your real time location, go to the Multi Sensor recorded option and select what you want to record. If you have any trouble get in touch with me directly. Cheers.
No decibel
You should really add the decibel value!
App works fine - impressive!
Does a nice job of displaying output of all the phones sensors. Easy to use. Straightforward menus. No errors yet.
Sensors Play vs Sensors Pro
Iβm still trying to figure out the difference between the two app. I brought this one before noticing the other app. I like the darker blue background of Sensors Pro, is there a way to match that in Sensors Play? I donβt know, not that I can tell.
If it was clarified the difference between the two apps (see above) and if custom background colors/gradients were an option, that would make this a 5-star app!

Barometric Height Surveys
I am undertaking an engineering investigation of a water pipeline through heavy rainforest. Although I can get OK GPS location fix of the route, I had not been able to get reasonable elevation fix using GPS due to the terrain and tree cover. Sensor Play has preformed brilliantly using a 2 station relative barometric elevation setup with an estimated accuracy of about +/- 1m over the alignment. The alternative survey was cost prohibitive. Sensor Play is a serious piece of kit for serious data collection. Thank you Philip Broder. Best $8 I have ever spent!

Thank you for such great feedback John, glad to have been of help deep in the rainforest! Get in touch directly if you need any further bespoke work or modifications.
