## What is Gyroscope+ Level IMU Logger?

Gyroscope Meter transforms your iPhone into a precision rotation sensor with a beautiful attitude indicator display. Measure angular velocity in degrees per second across all three axes and visualize device orientation in real time.

The aviation-inspired attitude indicator shows roll and pitch with a realistic sky/ground horizon, just like a real aircraft instrument. Track roll, pitch, and yaw with dedicated value panels for each axis.

Key Features:
- Real-time attitude indicator with sky/ground horizon
- Angular velocity measurement in degrees/second
- 3-axis rotation rates: roll, pitch, and yaw
- Peak rotation rate tracking
- Real-time rotation chart with axis-colored traces
- Adjustable sensitivity for different scenarios
- Min, max, and average statistics
- Dark, professional instrument-style interface

From testing device sensors to measuring spin rates in sports, Gyroscope Meter provides reliable rotation data in an intuitive format. The attitude indicator responds instantly to device movement, giving you a clear view of orientation changes.

Ideal for engineers, developers testing motion sensors, physics students, aviation enthusiasts, and anyone exploring rotational dynamics.


## Version history (last 5 releases)

### 1.0.30 — 2026-08-21

Fixed the tilt axes: roll and pitch are no longer swapped, so the bubble level and artificial horizon now read correctly — including a phone lying flat, which used to show the wrong angle. Steadier, more accurate readings overall.

Thanks for the reviews and feedback!

### 1.0.29 — 2026-08-14

Axis fixes, from your reports.

• Roll and Pitch were swapped — tilting the phone side to side moved the row labelled Pitch. The numbers and the labels now follow the phone's own axes.
• The artificial horizon was transposed: banking slid it up and down instead of rotating it.
• Turning right now increases the compass heading instead of decreasing it.
• The sensor health table blamed the wrong axis for bias and noise.

### 1.0.28 — 2026-08-06

Ads no longer interrupt you mid-task. Anything full-screen now waits until you have finished what you were doing, and the app stops showing a blank pause where an ad failed to load.

### 1.0.27 — 2026-08-05

Starting a measurement is no longer interrupted — the app gets straight to work, and anything that needs your attention waits until you are done.

### 1.0.26 — 2026-08-03

Thanks for using our app! This update brings behind-the-scenes performance and stability improvements for a smoother, more reliable experience. Your support means the world to us.
