## Most critical reviews (3 lowest-rated)

### 1/5 — Very inaccurate

*2024-11-24*

It says I’m infinitely going down, huh? This doesn’t work

### 4/5 — Inertial measurement

*2024-02-18*

Really great to see this app, and very useful for demonstrating how errors in inertial measurement develop.
Thank you for developing and publishing it!
Possible areas for improvement
Have separate information for each sensor eg accelerometer x, y, z, and gyro x,y,z.
Have more precision on acceleration display (with the ability to apply a low pass filter to remove high frequency noise)

### 4/5 — It’s a nice idea

*2024-01-15*

Too bad the iPhone doesn’t have all the sensors needed.  I wonder if you could use GPS for calibration.
