iPhone and iPad - SensorLog Remote server and client: You can now connect your iPhone and iPad (as a SensorLog Remote client) with a SensorLog App running as SensorLog Remote server. From your SensorLog App running as SensorLog remote server you can start and stop logging on the connected SensorLog Remote clients. - Visualize sensor data of connected SensorLog Remote clients on your SensorLog remote server - Landscape mode for iPad - Streaming in server mode now allows multiple clients to connect to SensorLog (before only one client connection was possible) - App operation in the background is not supported on iPhone and iPad anymore, according to Apple’s background operation guidelines. - "Lock Screen" feature to keep app in foreground for long term logging and streaming - added feature to share all files at once as zip archive - Siri and Shortcut Support: SensorLog recording (logging) can now be started via Siri or Shortcuts. Therefore define your shortcuts via Apple's shortcuts app and use Siri to stop and start recording / logging. - CLLocation speedAccuracy and courseAccuracy data added to log data Watch: - HealthKit / Store data export as csv and JSON format - SensorLog Remote client mode: Connect your Watch (or multiple watches) as SensorLog Remote client with your iPhone or iPad running a SensorLog Remote server. From your iPhone or iPad you can start and stop logging on your connected watches. - SensorLog Remote client mode: Send sensor data to iPhone or iPad SensorLog remote server to be visualized. - added feature to send all log files at once to iPhone - Siri and Shortcut support: Setup the shortcuts on your coupled iPhone and set the details of your shortcut (defined via Apple's shortcut app) so that it is also shown on the apple watch. Siri on your Watch then recognizes the shortcut command and starts "log to file" on your Apple Watch. - CLLocation speedAccuracy and courseAccuracy data added to log data

Price History of SensorLog

Description of SensorLog

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. Sensor Data Watch: For sample log files, please visit the SensorLog homepage (link App Support). - CLLocation, CMAccelerometer, CMDeviceMotion, CMActivity, CMPedometer, CMAltimeter, battery info

Reviews of SensorLog

  • 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. 👍
  • 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.
  • Stream mag data on watch

    Is it possible to enable mag data recording on watch? Didn’t find that option.
