Camera Angilator contains no online features.

There are no ads and no premium features, and no pay walls.

You may have heard of aps that collect your private data and sell it.

Perhaps you're worried about how secure your information is.

Camera Angilator will not ask you for any data private or otherwise. There is no login. No email address. No passwords. No personal information of any kind.

The photos you take are stored on your own device. If you have your photos linked to a cloud service, they can be uploaded there. We will not share your photos simply because we cannot access them. Camera Angilator merely stores the photo directly onto your own device, and anything you choose to do with it after that is completely up to you.

Camera Angilator will ask for access to your location. If you choose, it will add your current GPS location to the screen and include that in the photos you take.

This can be helpful for later reference. It can be handy to document where you were standing at the time, and it can be useful when discussing your results with others. You can verify you really were where you thought you were.

In the Options menu, you can enable/disable the GPS location display.

If you have the feature enabled, Camera Angilator will display your magnetic compass heading.

The compass feature is based on your device's magnetic compass sensor.

Accuracy Limitations

The accuracy of the magnetic compass can be limited and varies device by device.

Each device will have its own procedure to calibrate its magnetic compass.

I have found that the compass is often less reliable when the device is held upright, and this is the orientation Camera Angilator is intended to be used.

Use the compass display as more of a guideline than a precision data point.

"Tilt" refers to the side-to-side angle of your device. To get a perfectly horizontal picture, you want the Tilt to display 0 degrees.

It can be hard to hold the phone level without a tripod. For this reason, there is an "auto-lock" feature. (See below)

"Elv" is short for elevation, and it refers to the up-and-down angle of the device. This is the primary purpose of this app - to show you the angle you are looking up or down.

You might specifically want to take a picture exactly at eye level (where Elv shows as 0 degrees). There is an "auto-lock" option to help you with that. (See below)

Tap the camera icon at the center-right of the screen to take a snapshot.

Each time you take a picture, 2 images are saved:

One copy looks like the screen you are seeing with the overlays showing the angles, coordinates, date, etc. This file will be named with the current date and time followed by _Image.jpg

Simultaneously, a full-frame image will be stored with none of the overlays. This fill will be named with the current date and time followed by _Raw.jpg

You can use the image with the overlays to see your location and angles. The raw image can then be used to see the full detail and beauty of the original scene.

If you use the zoom feature, you will notice the raw image is not zoomed in. The zoom feature is purely digital. The raw image stores the full-resolution original image so that you can edit it however you wish without losing resolution.

The snapshot is only taken when you release the camera button.

If you're trying to capture a particular angle, it can be hard to hold the camera steady enough. It can help to hold the camera button down while you're trying to line up, then carefully release the button to take the picture.

At the bottom-right corner is the Auto-Lock button.

Tap the icon to enable Auto-Lock mode. (The icon will turn green to indicate it is active.)

Once activated, Auto-Lock mode will automatically take a snapshot as soon as the camera is level.

It can be hard to hold the camera steady while trying to line up a shot. Auto-Lock mode helps you catch that perfectly level shot.

Auto-Lock has 2 modes:

Tilt Only mode waits until the device is perfectly level in side-to-side tilt.

Tilt & Elevation mode waits until the device is level in both side-to-side tilt AND up-and-down elevation.

To zoom in and out, touch the screen with 2 fingers. Move your fingers closer together or farther apart to adjust the zoom level on the display.

This feature is strictly a digital zoom. This will result in a reduction in resolution for the image, but the raw copy will still record a full-resolution image.

The images recorded by Camera Angilator can be found on your device in the same folder (or a subfolder) where photos are normally stored.

On Android devices, you can find these images in DCIM\Angilator

On Apple devices, you can sync your images through iCloud or other means.

If you plug your Apple device into a Windows PC, the filenames are strange, but they can be accessed using File Explorer.

To open the Options, tap the gear icon.

Show GPS enable/disable the GPS coordinate display on your screen.

Show Date enable/diable the date display on your screen.

Show Compass enable/disable the magnetic compass display on your screen.

Haptics enable/disable the vibration haptics. (Your phone should vibrate slightly when you take a picture.)

Show Image if enabled, the image captured will automatically be displayed when you take a picture.

Auto-Lock lets you choose from 2 options.

Tilt Only takes a photo when the side-to-side tilt of the device is level at 0 degrees

Tilt & Elevation takes a photo when side-to-side tilt and up-and-down elevation are BOTH level at 0 degrees.

Calibrate starts the calibration feature.

Help brings you to this page

Image at the bottom-right of the Options screen is an image icon. When you take a picture, the most recent photo can be viewed by hitting this button. The button will be grayed out if you haven't taken a picture yet.

In my own testing, I have discovered that some devices come with their cameras slightly misaligned from their accelerometers. For this reason, I have included a calibration mode.

In calibration mode, you will be asked to point your camera at a distant object and then line up on that same object with the device upside-down. The offset is used to correct for any tiny misalignment.

For best results hold the camera very still, and focus on a very distant object somewhere near eye level.

In any case, Camera Angilator is not a precision tool to replace proper worksite equipment

Finally, most modern devices include an automatic image stabilization feature. These work by moving the image to counter-act movement of the device itself and produce a stable image.

This feature can introduce a significant error to the angles being displayed.

If you want accurate results, you should disable any automatic image stabilization features on your device when using Camera Angilator.
