Settings
Appearance
Show status bar
Use this setting to switch the status bar visibility on and off.
Show coordinates
Use this setting to display the current coordinates in the status bar. In the Deep zoom mode, only approximate coordinates will be displayed.
Scrollbar orientation
Use this setting to set the scrollbar orientation.
You may choose from the following options: shorter device's edge, longer device's edge, top, bottom, vertical (primary hand side).
The app adjusts the position of the buttons to the position of the scrollbar and the available space. When your device use gesture navigation, the app leaves appropriate margins depending on the system gestures sensitivity.
Large buttons and menu items
Use this setting to enlarge buttons and menu items, making them easier to touch. May push the scrollbar to the bottom ignoring your preference.
This setting is not available on devices with screens big enough to use large buttons by default, or too small to fit large buttons.
Hide zoom buttons
Use this setting to hide zoom buttons for a cleaner interface.
This is particularly useful on devices where the optional large buttons might clutter the screen.
Hide scrollbar menu button
Use this setting to hide the scrollbar menu button 
when swipe gesture is available, and access the menu exclusively through sweeping.
Scrollbar menu sections always expanded
Keep all the scrollbar menu sections always expanded, just like it was before the 3.4 update.
Left-handed layout
Mirror the interface for left-hand use.
Show grid
Use this setting to display a grid that helps center the image.
Small tags in the palette editor
Use this setting to reduce the height of the color tags in the Palette editor.
Advanced mode
Use this setting to switch the Advanced mode on and off.
Hide preview OK button
Use this setting to hide the OK button on the Advanced image control screen. You may simply tap the preview to confirm your changes, so this button is not necessary.
Behavior
Smooth movement deceleration
Use this setting to control the duration of the manual image movement deceleration (pan, zoom, rotation, and stretching). Select the "Never stop" option to make the movement continue until you stop it by tapping the screen. Disabling this feature can reduce the battery consumption.
Palette adjusting
When this setting is switched on, the app automatically adjusts the palette length and offset after a paint mode change.
See the Adjust now option description in the Paint parameters section for more information.
Reset coordinates on parameter change
When this setting is switched on, the app automatically sets default coordinates and zoom after you change the value of the fractal parameter at zoom 10 or higher.
This helps to avoid a blank image that might appear if the fractal with new parameter value will not have any details in the current coordinates and zoom. Instead, you will see the entire picture of the changed fractal.
Smart scrollbar switching
Use this setting to enable or disable the Smart scrollbar switching.
Interior stabilization
When this setting is switched on, the app automatically switches from the detail level control to the iteration limit control after you set interior paint mode.
See the Controlling iteration limit section for more details.
Back action undo
Use this setting to customize the device's Back action.
Admire mode
Use this setting to customize the Admire mode.
Disable tutorial hints
Use this setting to disable popup messages with tutorial hints. Not recommended if you are not familiar with the app, as it may make you miss out on some useful features.
Auto-zoom
Auto-zoom speed
Use this setting to change the speed of real-time zoom videos.
You may choose a speed from x1.2s (which means that zoom is changed by 20% per second) to x6/s (really fast).
This setting is also applied to zooming-in by long-pressing the screen.
Auto guiding
When this setting is switched on, the app automatically adjusts coordinates during real-time zoom-in video to avoid areas without details. This is an experimental feature not working perfectly yet.
Touch to set center
When this setting is switched on, you may touch the screen during real-time zoom video to set the coordinates to that point.
Use the stop button 
to stop auto zooming.
Aim sight
When this setting is switched on, the app displays an aim sight at the screen center during real-time zoom controlled by tilting the device. It can help you to choose where to move on.
Auto-zoom on long press
When this setting is switched on, you can zoom-in the image by long pressing the screen. It was the built-in feature prior to version 3.1, but is now disabled by default.
Image rendering
Iteration limit
Use this setting to change the maximum iteration count in the Advanced mode. See the Controlling iteration limit section for details.
Interior prediction
When this setting is switched on, the app optimizes image rendering performance by guessing fractal interior pixels basing on the pixel surrounding.
This optimization may produce some inaccuracy and can be done only when interior paint mode is set to Solid (which is always true in the Simple mode except for the Lyapunov fractals). It may be useful while rendering an image with a large interior area and with a high iteration limit.
Save location in image metadata
Use this setting to save the location (including your custom content) in the image EXIF data when saving or sharing images. This allows you to open locations from images.
Include custom photos in the location data
Use this setting to include your custom photos in the location data when saving images or sharing images and links.
NOTE: this can make the resulting files much larger.
This setting is disabled by default (the default photos are used instead).
Advanced video settings
This section settings described in detail in this section of the tutorial.
Encoder
Select a video encoder from those available on your device.
Color format
Select the color format of the images delivered to the video encoder.

About
Displays a short info about the app including the version number.
Privacy Policy
Displays the app's privacy policy.
What's new
Shows the app's change log with the changes from the latest update at the top.
Save custom content
Save your favorite locations, custom fractal types, paint modes, and palettes to a JSON file. Use it to backup or to transfer content to another device.
You may opt for human-readable format. NOTE: on devices running Android versions prior 7.0 the file may contain encoded coordinates for zoom factors greater than 1e+12. Do not use human-readable format to be able to load the file containing locations with zoom factors greather that 1+e12 on devices running Android versions prior 7.0.
Restore custom content
Restore favorite locations, custom fractal types, paint modes, and palettes from a saved file.
WARNING: your current custom content WILL be deleted and replaced by the file content.
Restore default settings
Restore the app's default settings. All permanently dismissed tip messages will be displayed again.
Show the intro again.
Your favorite locations and custom content WILL NOT be deleted.
