## What is AccelMeter?

First and only 3D-graphical Vector Accelerometer in App Store: Smoothly visualize and measure the current acceleration. It can be used on earth, on moon or in orbit (where relative would be equal to absolute mode - please prove) to visualize the direction and strength of the gravitation - or simply at home to measure the g-forces you reach while shaking your phone - however be warned if you tend to get to the limits! :-). A fun application is to place the iPhone/iPod steady in your car (or any other moving vehicle), go to relative mode, zero it once when you are standing and then see the current g-forces in effect while you drive (e.g. what g-force does your car get when you accelerate?).

The application has five different display modes for acceleration visualization:

- Absolute Mode: Displays the reverse acceleration of the iPhone (1g up when hold steady). 

- X-Rotation - Y-Rotation - Z-Rotation: The arrow will display the rotation around the X-, Y- and Z-Axis of the iPhone. The digital indicator shows the angle numerically (-180° - +180°). A way to calibrate will be added with one of the next updates, so you could use this as a level.

- Relative Mode: This mode shows the relative strength (absolute minus compensation vector) of the acceleration.


For a detailed documentation, please visit our product homepage. 


For recreational use only. However it CAN (!) be very accurate. The measurement is performed as good as possible (we try our best) by using the inbuilt accelerometer and magnetometer to their limits. The range of the accelerometer typically has a max of ±3g (~4.2g displayed here if combined). However, tell us your experience!

### 4/5 — Intéressant

*2021-10-14*

Belle appli, mais je n’y comprends pas grand chose pour le moment. Le manuel est trop succinct.

### 2/5 — Confusing to figure out

*2019-04-23*

Once I was able to figure out how to use the app and find my acceleration it was fine. But it gave me my acceleration in g’s so I had to do some math to get my actual acceleration.

### 2/5 — Good But Confusing

*2019-04-18*

The app gave me my acceleration, but it was not clear with how to find your acceleration using the app. This app is good if you know how to use it, but I didn’t and could not find any directions. I had to get help just to find out how to see my acceleration. Not beginner friendly.

### 2/5 — Decent

*2017-04-20, version 1.6*

We had an iPhone 5 SE. We tilted the phone to test it, we expected it to do what it did although it wasn't as accurate. It was  relatively difficult to use, and I suggested to Torio on how to use the app.We had an iPhone 5 SE. We tilted the phone to test it, we expected it to do what it did although it wasn't as accurate. It was  relatively difficult to use, and I suggest a tutorial on how to use the app.

### 1/5 — Difficult and Not Intuitive

*2017-04-20*

I couldn't figure out how to use the app let alone test it because there were no directions and the app is not intuitive. I tried to walk and measure my acceleration but it was difficult to understand the numbers given. Maybe an instructional video would me helpful.

### 2/5 — Good but confusing

*2017-04-20*

I have an iPhone 5s, and I tested this app by walking around a room while increasing and decreasing my speed. It did not work as expected because I expected it to be easier to use. It would have been a lot better if there was a tutorial or instructions.

### 3/5 — App

*2017-04-20*

My teacher (kwetee wetee) recommended this app and it was fun! I thoroughly enjoyed the app and but it wasn't precise

### 4/5 — Good app

*2017-04-20*

I like the app however....If the app gave you a place to calculate your weight and the app calculated the acceleration when you open the app it would earn my 5th star.

### 5/5 — Nice app

*2016-01-26*

Good application

### 3/5 — It works but complicated

*2015-04-23*

At first when I used this app I had no idea how to use it. We would walk back and forth and nothing would show acceleration. This is because the app shows the absolute acceleration when it is first opened. Once I figured this out everything worked fine. The only thing that would make this app better is if it gave you a walk through of the app when you first opened it. Also if they labeled the buttons on the app it would help. Other than that it works great

## Frequently asked questions about AccelMeter

### What does the AccelMeter app do?

This app provides a 3D graphical visualization of the current acceleration acting on your device. It allows you to measure the strength and direction of acceleration, including gravitational forces and g-forces experienced during movement.

### What are the different display modes available?

The app offers five display modes: Absolute Mode for reverse iPhone acceleration, X-Rotation, Y-Rotation, and Z-Rotation for visualizing rotation around each axis with numerical angle indicators, and Relative Mode to show the difference between absolute acceleration and a compensation vector.

### Is AccelMeter free to use?

Based on the provided information, AccelMeter is a paid application. It does not feature in-app purchases or advertisements, indicating a one-time purchase model.

### What devices is AccelMeter compatible with?

The description mentions its availability on the App Store, suggesting compatibility with iOS devices like the iPhone and iPod. Specific iOS version compatibility is not detailed but it utilizes the device's built-in accelerometer and magnetometer.

### How can I use AccelMeter for measuring car acceleration?

You can place your iPhone steady in your car, select Relative Mode, and zero it while stationary. The app will then display the current g-forces experienced as your car accelerates, allowing you to measure the g-force of your vehicle's acceleration.
