Description
Sensor Logger collects, records and displays data from a wide range of sensors on your phone & Wear OS watches — including accelerometer, gyroscope, GPS, audio, camera and bluetooth devices. You can also log device properties such as screen brightness, battery level and network state. An intuitive interface allows you to select your desired sensors and preview them live. A tap of a button initiates the recording function, which works even when the app is in the background. You can view and manage recordings within the app via interactive plots. The export functionality conveniently outputs your recordings in a variety of formats, including Zipped CSV, JSON, Excel, KML and SQLite. For advanced use cases, you may also stream data via HTTP or MQTT during a recording session, resample and aggregate measurements from multiple sensors, and create Studies to collect recordings from other Sensor Logger users with ease. Sensor Logger is specifically designed for researchers, educators, and anyone with an interest in collecting or monitoring sensor data on their smartphone. It serves as a toolbox for exploring various fields, including physics, science, technology, engineering, and mathematics (STEM).

Unable to log sensor data from my Galaxy Watch 7 Ultra or Polar H10 chest strap, sole reason for paying for this app was to compare both heart rate sensors.
★★★★☆Peter Adams· Oct 20, 2023
Overall great app. Using it to collect some preliminary data before we build our something more specific to our use case. The biggest downside has been trying to interpret the exports pushed to our server. Some of the data points aren't documented, so we don't know what they are (for example "accuracy" comes over as 1 or 3 - but we have no idea what either means). The app is great, but there are a few holes in documentation, so we can identify what we're looking at.

Great app, easy to use. I would love an option to set a custom sample frequency. I would personally use 24Hz to use the data in VFX context.

Temperature option is missing. Please add. Looking for simple tool to log hourly temperature from phone sensor.
★☆☆☆☆Vincent B.· Apr 2, 2023
Last update locked a lot behind a subscription that was available before. You could record as many as you runs as you want, now you can only save up to 10 for free. And some sensor data aren't available anymore without paying. At has also bugs where it just doesn't record some raw data.
★★☆☆☆Philipp Skorobogatov· Nov 2, 2025
Good app, but unfortunately can't run in the background regardless I allow it. So unusable

Paid for upgrade but was never able to use it. App kept trying to get me to purchase the monthly subscription over again.
