## SensorLog Description
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.

The most important functions for iPhone and iPad:

- Sensor data can be recorded at up to 100Hz (depending on the iOS device version and sensor type).
- Sensor data can be streamed in server or client mode using TCP or UDP. Depending on the network speed and the server or client configuration used, this is possible with up to 100Hz.
- Via HTTP(S) GET/POST request, sensor data in JSON format (POST) or form-url encoded (POST and GET) can be transmitted to a REST API with up to 20Hz.
- With the SensorLog Remote Client/Server function, an iPad or iPhone can connect as a SensorLog Remote Client to an iPhone or iPad, which takes on the role of SensorLog Remote Server. The client's sensor data can be visualized on the server, and the server can control the clients (start/stop logging, start/stop sending data).
- Logging can be started and stopped using Siri and shortcuts.
- SensorLog supports Core ML models created with Apple's Create ML app. Log data with SensorLog, train a model with the data in Create ML, load exported models in SensorLog and log the model prediction. Supported Create ML models are: Activity Classifier, Tabular Regressor and Tabular Classifier.
- If you have an Apple Watch, HealthKit data such as heart rate, energy used, sleep and movement data can be exported on the watch as a csv or json file and then transferred to your iPhone.

Sensor data iPhone / iPad:
For sample log files, please visit the SensorLog homepage (link App Support).
- CLLocation, CLHeading, CMAccelerometer, CMGyroData, CMMagnetometer, CMDeviceMotion, CMActivity, CMPedometer, CMAltimeter, WLAN and network provider IP addresses, device orientation, battery info, decibels.


The most important functions for Apple Watch:

- Logging Option 1: Logging duration up to 1 hour
Simultaneous logging of all selectable sensor data is supported in the background with up to 50Hz. Individual sensors can be logged with a higher frequency of up to 100Hz. Sending data via HTTP requests is supported.
- Logging option 2: Logging duration greater than 1 hour
In the background only logging of the accelerometer data with max. 50Hz is supported. In the foreground all sensor data with up to 100Hz. Sending data via HTTP requests is only supported when the app is in the foreground.
- Via HTTP(S) GET/POST request, sensor data can be transmitted to a REST API with up to 10Hz in JSON format (POST) or form-url encoded (POST and GET).
- The Health Store data feature off the SensorLog Watch app allows you to export HealthKit data like heart rate, energy burned, sleep, and movement data. This data is automatically recorded by your Watch and can be read out and exported by SensorLog as csv or json file and transferred to your iPhone.
- Logging can be started and stopped using Siri and Shortcuts.

## SensorLog Reviews in United States

### *---- "Crashes on the watch"
As soon as I start recording on the watch the watch app crashes.  This is my use case, so 1 star.
-- Sassie Mollassie, 2026-05-17

### ***** "WELL DONE!"
this powerful app is easy to use and does what is advertised.
-- Best-clocks, 2025-08-12

### ***** "Amazing free app, more features than even paid apps."
I was looking for an app that could steam device accelerometer data across the network to my PC. This app offers that and more, all for free.
-- TheEmployed, 2024-08-23

### ***** "Amazing"
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. 👍
-- SomeDude4w5234, 2024-02-03

### ***** "Awesomeness"
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.
-- Royalty Wazer, 2023-05-26

### ***** "Stream mag data on watch"
Is it possible to enable mag data recording on watch? Didn’t find that option.
-- meloniceice, 2022-04-12

### **--- "Help!"
Why does the pedometer not work?
-- Prickly Pig, 2022-02-05

### ****- "Good and easy to use app"
This is a great app to log the Watch sensor data. I like the fact that you can log data on the watch for long term monitoring.

I am using this for my these to record hand motions in patients.

I wish the app could record for 24 hrs without needing to trigger it every 12 hours. Is there a work around ?

Also I wish the gyroscope was logged along with accelerometer in background logging mode.

Great app otherwise!
-- jalponcho, 2021-11-14

### **--- "Sampling rate has bugs"
I set the sampling rate to 60 hz, but the logged data has samples with sampling rate  around 33!
-- Fati-El, 2021-10-04

### ***** "Optional Axis Selection for Unbiased?!?"
Anyway you could add a feature that enables the user to select the Preferred axis for “Unbiased Device Motion Data”? As the app currently stands, it’s only fixed to one plane. :( It would be very useful... Apart from that excellent app!
