User reviews

Sensor Logger is praised for its ease of use, comprehensive sensor support, active development, and excellent documentation. Users appreciate the clean interface and the developer's responsiveness. However, recent updates introducing subscription paywalls for key features have caused dissatisfaction. Additionally, users report incomplete data documentation, occasional bugs with data recording and file access, and certain usability issues like coordinate inconsistencies and default graph settings. Overall, it's a highly capable app favored by programmers and researchers but has areas needing improvement, especially regarding pricing and documentation.

Pros

App is easy to use with a clean and intuitive interface.
Supports all sensors and allows real-time visualization and exporting of sensor data.
Active development with amazing documentation and responsive developer support.
No annoying ads; overall a fantastic app for logging sensor data for programming and research purposes.
Integration capabilities with external tools (e.g., Gyroflow) and servers for advanced data analysis.

Cons

Recent updates have locked many features behind a subscription paywall, particularly data export and saving data runs.
Lack of complete documentation for some exported data points, making interpretation difficult.
Some bugs present such as sensor data not recording properly and issues with file access on devices.
Inconvenient default behaviors like the graph origin set to zero Unix time requiring zooming in to view data.
Certain features like custom sample frequency and coordinate system consistency are requested but not fully supported.
