PowerSense is a powerful motion sensor logging tool that can track and record various sensor data on your iPhone and Apple Watch. These sensors include accelerometer, gyroscope, magnetometer, etc. The recorded data is stored as .csv files and can be then sent out via email, AirDrop to your Mac or upload to your linked Dropbox account.

You can configure the sampling rate to be from 1 to 100 Hz for phone. 50 Hz is fixed for watch.

From version 2.0 onwards, advanced features like multiple-file upload, data file compression, AirDrop transfer and Dropbox upload would be available in Pro version via In-App Purchase.

# iOS 10.0 and watchOS 3 are required.
# Continued use of GPS running in the background can dramatically decrease battery life.

Ratings and Reviews

Excellent but not the shake to delete all function


Very useful tools and collect quite complete sensor data. I used this for my research and it has been going on great.

Please get rid of the stupid feature of "delete all" shortcut triggered by just shaking the phone while on the file tab. I lost one week of data because of this. This is very annoying for collecting data while running or in a car.

Developer Response

Thanks for the feedback and sorry to hear you had the trouble with it. I'm going to push a update to fix it.

Best I've found.


I needed an app that could capture watch sensor data. It does. It offers different types of data to capture. It exports logs for easy excel graphs. Simply put, it does what it says it does. I paid for the pro and love it. I have provided feedback to the developer for some extra features but it already is a great app in its current state.

Great app, exactly what I was looking for.


I needed a simple motion sensor for my research purposes but I have zero knowledge of programming and creation of electric circuits. If this program will prove to be stable and be able to work for at least 24 hours without lagging, it will perfect for me.
