简介

Sensor Logger collects, records and displays data from a range of sensors on iPhone, Apple Watch, iPad and AirPods — including accelerometer, gyroscope, GPS, audio, camera and Bluetooth devices. You can log device properties such as screen brightness, battery and network state. Select and preview desired sensors in a few taps. A single tap initiates the recording function, which works even when the app is in the background. View and manage recordings within the app via interactive plots. The app supports many export formats, including Zipped CSV, JSON, Excel, KML and more. For advanced use cases, stream data via HTTP or MQTT, resample measurements from multiple sensors, create Studies to collect data from other users systematically and write custom automation rules based on sensor, time and location. Once you have collected your data, you can create Stories — data-driven dashboard with your recordings, hosted online for effortless sharing.

Sensor Logger is designed for researchers, educators, and anyone interested in collecting or monitoring sensors on their smartphone. It serves as the ultimate toolbox for exploring various fields, including physics, science, technology, engineering, and mathematics (STEM).

Studies & Sensor Logger Cloud

Create Studies to collect data from other Sensor Logger users efficiently. When activated, Studies use the investigator's specified sensor configuration for consistent data collection. Participants can upload their recordings to a secure cloud and join, pause, or switch Studies anytime. Studies include clear data usage descriptions, privacy statements, and contact details to ensure privacy compliance. Customize Study size, duration, sensor configuration, and export formats.

Geek’s delight, help for weather-sensitive pain

This app may be life-changing for me, more on that in a bit. First I have to say how pleasant it is to use. The UI is easy on the eyes, and the controls are fairly intuitive given how much functionality and flexibility it packs in. Just reading through the list of measurements that my iPhone can collect is already educational and fun. I’m making a list of people who I need to tell about this, they will love it!

But I’m not playing around, I’m on a mission. I have weather-sensitive fibromyalgia, and the science of how weather affects the health is not moving fast enough for me given how much I suffer day-to-day. I have been using an app that is useful for keeping charts of air pressure changes over time, but it has a conventional meteorological orientation. For starters, I live a little more than a mile above sea level and apps that insist on reporting my 830 mbar as 1030 mbar just… irritate me. More to the point, this app gives me total control over how frequently observations are collected. I’ve been using it for one day, and I’m already seeing patterns emerge that would never show up in the best data I could get before. (Not the ones I expected, but the ones that seem obvious in retrospect, which is always a good sign when you’re looking for answers.)

Great

Very helpful app for vehicle testing and analysis.

Concerning privacy practices

The app seems much better designed than many of the competing sensor apps available. That said, after trying it out, I’m not comfortable with it from a privacy perspective. It asks for permission for precise location and Motion & Fitness, even when you aren’t collecting that data. When you say no, it leaves bright yellow triangles on the screen, presumably intended to scare or annoy the user into granting permission. There is a privacy policy in the app, but it’s rendered in light grey text on a white background and is unreadable. The data this app collects is sensitive, so trust is critical, and I don’t feel like I can trust this app.

Thanks for the feedback, the contrast on the privacy screen will be addressed in the next release. The permissions warnings are designed to indicate clearly which sensors may not be available for recording due to a lack of permissions (especially for reliably background recordings, which is a common use case for Sensor Logger), and are not intended to scare or annoy.
