Sensor Data Recorder is a utility for developers and researchers to capture labeled gyroscope, accelerometer, and audio data on iOS devices.
The App DNA
What makes this app unique?
It removes the connectivity dependency and privacy risks of cloud-based logging by keeping all sensor data local to the device.
For Developers and researchers requiring a mobile-based tool to collect labeled sensor and audio data for machine learning projects.
What does it look like?
Key features
Captures gyroscope and accelerometer data directly from the device CoreMotion module at user-defined frequencies.
Records microphone audio simultaneously with motion sensor data for multi-modal dataset creation.
Assigns custom labels to recordings to prepare datasets for machine learning or deep learning workflows.
How much does it cost?
The app operates as a free utility with no observable monetization mechanisms.
Velocity
Dormant developmentUX improvementsShow more...
Sensor Data Recorder has been inactive for 1,331 days, placing it firmly in the zombie category. There have been no feature updates, bug fixes, or operational changes in the observed history. The development momentum is non-existent, as the app has not received a single update in over three years.

Key takeaways for Sensor Data Recorder
Where is it heading?
The market for specialized data-logging utilities is consolidating around tools with active maintenance and cloud-sync capabilities. Sensor Data Recorder remains a niche, stable option for local-only needs, but its lack of updates will eventually force users to migrate to more active alternatives.
- The 1331-day update gap suggests the tool is in maintenance mode, which risks compatibility failures as iOS evolves.
The SWOT
- Local-only storage removes privacy-compliance barriers
- Real-time visualization would improve usability
Next best moves
Audit background-process compatibility because the three-year release gap risks session termination on modern OS versions → maintain core utility
The counter-intuitive read
The lack of monetization is not a failure but a feature…
Read the full takeSince the last report: The app remains in a dormant state, with no functional changes or updates recorded since December 2022. The primary shifts are limited to the documentation of the app's privacy model and a more precise framing of technical risks in the SWOT analysis.
Bottom line
Users report: Sensor Data Recorder serves a specific research need via its local-first data capture, but the multi-year inactivity creates a technical-debt risk for long-term projects. Maintaining the current codebase as a stable, open-utility asset is the only viable path forward.
