🏷️ About: With SensorLog you can read sensor data from the iPhone, iPad and Apple Watch. The sensor data can be saved as a file in CSV or JSON format, streamed via TCP/UDP or sent as an HTTP request.
App measurement data collection is easy to initiate but limitations in the output measurement file time tags make the data useless for performing engineering analysis. I am using it to log time tagged earth magnetic field measurements. I tried to log the data at 100 hz but when I inspected the data file the time tags only have 1 decimal point of accuracy (0.1 sec) and there are multiple rows of data with the same time tag; thus when I collect data at say 100 hz, the data entries are not exactly 100 hz but some mismatch of approx 100 hz.
Any way I can force the output to be exactly the hz I want.
Also can you increase the time tag accuracy down to at least the hz you are collecting data at (e.g. If 100 hz data collection, then time tags accurate to 0.01 sec).
Without these fixes to you app, your app is worthless for engineers using it for engineering applications.
Any idea how to get it installed in my watch? It appeared once but disappeared and never come back
Why does the pedometer not work?
I set the sampling rate to 60 hz, but the logged data has samples with sampling rate around 33!
Pretty much works and sends files as described. Currently on my iPad, the gyro and core display screens are blank. I'm not sure if I need to configure or if this is an ipad2 feature. Either way it's still cool. Thanks.
this powerful app is easy to use and does what is advertised.
I love all of the export options provided, and it’s great that the developer continues to enhance SensorLog . Apple Watch support is fantastic.
A great app for reviewing all of the sensor data your phone is processing. If APIs are available, WiFi signal strength would be a useful addition.
Berne has been working with me on a beta version that is working pretty well.
Is it possible to log gyroscope data from apple watch
This is what software is supposed to be. It works, it’s simple, it’s to the point, and it had a simple, no tricks pay once structure. After coming up with a project a couple years ago I finally implemented a POC of integrating sensor logs with an esp32 mesh network controlled by orange pi 5 plus. Works great, incredibly simple since all the hard work of the server setup is done. What’s better is how easy the config process is. Literally all the things you want on one screen. Bonus for downloadable configs!
Apps like this are why I’ve started making more of my own apps/projects. It’s hard to argue with special purpose no frills or trying to sell regurgitated poorly modified open source software (how many camera apps does one need to pay for that all utilize the same underlying software….poorly?). This is true software. Made by someone for a purpose which wasn’t to “get rich” quick selling bad derivatives.
Bravo. 👍
Awesome app for raw sensor data. However now with AR we have access to an additional, very awesome metric: accurate positional data in a world scene. It would be super cool if one of these sensor-logging apps supported it.
SensorLog does exactly what I need it to do. Within 5 minutes of downloading it, I had a CSV file containing the sensor data of interest.
I highly recommend SensorLog.
Is it possible to enable mag data recording on watch? Didn’t find that option.
I was looking for an app that could steam device accelerometer data across the network to my PC. SensorLog offers that and more, all for free.
Anyway you could add a feature that enables the user to select the Preferred axis for “Unbiased Device Motion Data”? As SensorLog currently stands, it’s only fixed to one plane. :( It would be very useful... Apart from that excellent app!
This is the only app I found, after hours of searching, that provides a reliable data stream of gps coordinates and other sensors to a custom url (rest endpoint). Bernd is very responsive to questions! Recommend SensorLog to anyone seeking a way to stream data. Thank you Bernd!
Worked as expected and very easily.
I cannot say yet if it is accurate but was able to log data to a file and email it without hassle.
I need to just make sense of what the state options mean? Bernd can you explain perhaps? 0-5?
Good and simple app.
Thank you for writing this application. This is a perfect example of what high-quality software should be.
Works as intended, every time. Lets the user retain ownership of the data and allows individual collecting the data to use it for their purposes.
Amazing app to get raw sensor data for my research. I wish it can also extract some other data (esp. heart rate). I imagine SensorLog will be very popular with this added feature.
SensorLog is very safe to use.
