How to install an earlier version of ArtRage for iOS that is compatible with an older iPad 3 or other iOS device
If you are still using an older iOS version that is not supported by the latest update to the iOS app then you can still use the older versions of the app. To get the App Store to let you install an older version, you must already have the app listed as a download in your purchase history.
To install an older version for the first time try the following steps:
- Install the app on a compatible device or iTunes on the desktop first. it will then be automatically available to your older devices.
- Access the app from the ‘Purchased’ section of the App Store on your older device.
This should only affect users who are purchasing the app for the first time or are trying to reinstall after uninstalling the app. Anyone who already has ArtRage installed should not be affected by future updates. We do not remove older versions of ArtRage, so if you are still unable to install our app, you may need to contact Apple Support for further assistance or see their official FAQ.
The ‘stroke gap’ resembles a lag when using ArtRage but is actually part of the realistic painting process
Many new ArtRage users notice what appears to be lag when they first use the app. While ArtRage can lag when performing demanding operations, the ‘stroke gap’ is a consistent, non-performance related phenomenon. It is the possible area of effect for your next movement.
It exists as an empty gap between the leading edge of a stroke, and your cursor, or the pressure point of the stylus. This gap will stay empty until you move or lift the stylus (or finger).
It is part of ArtRage’s real time stroke calculations; much like painting with a real brush, the stroke on a canvas is not finished, nor visible, until you move the brush on (if you stop and hold a brush in one spot, you won’t be able to see the stroke that has not yet been finished in that spot).
Size of the gap
The size is based on your current tool size, so the gap increases with larger brushes. The gap is literally the ‘largest possible stroke that you could be about to make’. The larger the selected tool, the larger the gap.
It is extremely visible on mobile devices, because they do not have a cursor to indicate brush size. The Outline cursor on the desktop will circle the entire stroke gap, making it clearer that it is part of the brush stroke, and not just a lag in the program. You can see in the images below that the ‘stroke gap’ actually extends in front of your cursor as well as behind. The gap measures the distance between the midpoint of the stroke (i.e. where you are placing pressure with a stylus) and the end of the current stroke.
Why it Happens
The gap is there because ArtRage is waiting to see what you’ll do next. The next part of the stroke will look very different if you lift the stylus away, double back, change pressure, run into and blend with other paint, or just continue exactly as you are. It would be much more confusing to project a stroke that changed after you kept going.
How can I avoid it? It bugs me.
You can’t ‘turn it off’, as it’s built into the way ArtRage works, but you can reduce the visibility of the gap by zooming out of your canvas view, decreasing the tool size, experimenting with different tools (some display it more clearly than others), or by turning on the Outline cursor in the desktop versions.
It tends not to be noticeable once you become familiar with ArtRage, as you learn what will happen when you make particular strokes.
How can I tell if I’m seeing ‘stroke gap’ or real lag?
Stroke Gaps are constant
A stroke gap will always be a constant size as you draw, and will scale relative to the tool size.
To estimate the size the ‘stroke gap’ should be, make a full pressure ‘dot’ on the canvas with your current tool. The ‘gap’ will be about half the width of this dot.
Note that settings such as Softness (eraser), Hardness (Airbrush), Paper Wetness and Bleed (Watercolor) will affect the apparent size of strokes. For example, in the image below, you can see that the eraser make very different marks at 0% and 100% Softness. The 0% Softness is the closest to the actual tool size.
Lag varies depending on what you do
Lag will cause the stroke to be further behind as you draw longer, faster and bigger strokes, or as your device runs out of memory for other reasons (e.g. multiple apps running, large canvas sizes, little free space). It will not be directly tied to the brush size (though larger brushes use more processing power). There are a few ways to reduce the memory usage.
If you see a very noticeable difference between drawing fast strokes and slow strokes, or between drawing the same stroke at different canvas sizes, that is lag.
Note: Some mobile devices cannot process fast strokes above a certain speed. This isn’t ArtRage lagging, but a built in limitation of the device.
Why don’t the mobile apps support canvas rotation?
The ArtRage Mobile apps (iOS, Android and Windows Touch) don’t support canvas rotation (the ability to just turn the canvas around using fingers), but we added it as an option to the iPad app in 2015.
This is because canvas rotation is memory intensive feature which isn’t absolutely necessary, as it is possible to rotate the entire device. While we may consider adding this feature in the future, we will only add it if it does not compromise app performance. Currently, most devices will struggle with this feature.
How can I rotate the canvas?
ArtRage for Android
The entire canvas and interface will rotate as you turn the device. To prevent this, you can turn on “Lock Interface Rotation” under Settings.
ArtRage for iPad
Update 2.1 added canvas rotation to the iPad app, as most current iPads can now handle the performance requirements, and the iPad Pro is too large to physically turn easily.
- Default Setting: The interface will rotate as you turn the device, but the canvas will not.
- Canvas Rotation Active: You can turn ‘Canvas Rotation’ on by going into the menu > Preferences. This will allow you to turn the canvas using two finger gestures while you work.
- 15 Degree Increments: You can ‘lock’ the rotation angles to 15 degree increments in Preferences, or allow the canvas to turn freely.
ArtRage for iPhone
Neither the interface nor the canvas will rotate when you turn the device.
ArtRage Touch (Windows 8)
The interface will rotate as you turn the device, but the canvas will not. You can also use the Canvas Positioner to rotate the canvas. The Canvas Positioner is a floating ‘compass’ that allows you to turn, scale and move the canvas, similar to the desktop versions. Find it by going to Layers > menu button in the top right > Canvas Positioner.
Can I get a refund? I don’t want the app anymore.
The Google Play Store allows you to refund your purchase automatically within the first fifteen minutes, and we can refund purchases if you have a problem with your product (although not if you just got bored with the app), but we are unable to directly refund purchases made through GALAXY Apps or iTunes. You will need to contact the individual store support directly.
If you are having a specific issue with your app, please contact us and we will try and help.
I purchased ArtRage for Android from one app store. Can I transfer it to the other?
Unfortunately, the Google Play Store and GALAXY Apps are completely separate, and we have no way to transfer sales information.
Can I run my purchase on devices that don’t support the app store I bought it from?
Unfortunately, this isn’t possible. ArtRage app licences are tied to your app store account.
This will mostly only apply to users who purchased through GALAXY Apps (or received it free from GALAXY Gifts) and want to use ArtRage on a non-Samsung device.
Can I run my purchase on multiple devices that have the same app store account?
Yes! This is controlled by the policies and technology of each individual store, but we have no restrictions on you using the ArtRage iOS and Android apps across multiple devices.
ArtRage for iPhone App Incremental Update History
This app has been discontinued and replaced by a universal version of the full iPad app.
ArtRage for iPhone provides 8 painting and drawing tools with a set of variant types for a range of painted effects. The ArtRage painting simulation is still in there, letting you spread and blend thick oils, or bring out canvas textures with shading pencils, and the interface has been designed for quick and convenient operation on a handheld device. ArtRage for iPhone lets you share your paintings with other versions of the application, via the iTunes file sharing system or by email.
ArtRage for iPhone 1.1
- Updated for iOS 8 and larger phone screen resolutions.
- Fixed a bug that caused rendering artefacts on the iPhone 6 Plus – Paintings were being created properly but displayed with white bands.
ArtRage for iPhone 1.0.4
- Fixed a problem that could cause paintings to be created at 1/2 screen resolution on Retina devices.
ArtRage for iPhone 1.0.3
- Added support for iPhone 5 screen resolution.
ArtRage for iPhone 1.0.2
- Added properly upscaled tool icons for the tool pod on Retina Display devices.
- Improved the reliability of 3 finger tap to show/hide the toolbar.
- Fixed a problem that could cause paintings to fail to generate a thumbnail preview in the gallery if they are too large (eg. Retina display paintings displayed on a non Retina iPhone).
- Fixed a problem that could cause the Merge buttons when editing layers to update incorrectly after deleting or moving layers.
- Fixed a problem that prevented emails with Painting files attached correctly opening the Painting in ArtRage when tapped.
ArtRage for iPhone 1.0.1
- Fixed a crash bug that would happen on iOS4 when returning to the gallery. You should now be able to manage your files properly. This was due to an unsupported feature relating to gallery rename gestures.
- Replaced the non-working loaded palette knife preset. Please note that you may need to uninstall the app and reinstall it to see this change made, as the presets use files that the installer may not clean up. Before doing this, please back up your files.
What is the PTG Extension?
ArtRage paintings all use a unique, proprietary, file type, the .PTG extension. The file type can only be opened by ArtRage and can be used across all the different editions (including the free demos and iOS versions).
The reason we use a special file type is because ArtRage needs a way to preserve all the unique traditional painting aspects of the program, such as paint thickness, canvas texture, realistic colour mixing, lighting and how the different media should interact. It also records more standard attributes, such as layers and transparency, and preserves ArtRage-specific attributes such as pinned References, tracing images and symmetry.
What does “PTG” stand for?
PTG means “Painting” (PainTinG).
The iOS editions of ArtRage are compatible with multitouch swipe and tap gestures
iPhone and iPad Gestures

You can purchase and download the iPhone and iPad apps through the iTunes App Store.
iOS Device Tips
ArtRage is a processor intensive app that does a lot of work behind the scenes to generate realistic paint effects. This means that it is sensitive to situations where your iPad is using processor time on other tasks. In addition, if the OS detects that memory is low when you are using an app it may shut that app down without warning.
If you are experiencing any speed issues or crashing when using ArtRage for iPad or iPhone, it may help to clear out any parked applications and reboot your device (all versions).
How To Close Parked Apps:
Applications that you have run previously will not be automatically closed when you quit them, instead they are ‘parked’ in the background. Rebooting your device does not close these apps for you. While most apps should sit in the background without using too many system resources, it can help to close them if you are experiencing speed or crashing issues.
Here’s how you do it:
1. Double tap the Home button on the iPad/iPhone. This brings up the list of parked applications which scrolls from right to left.
2. To close an application, tap and drag upwards on its screen preview to drag the screen off the top. When the screen vanishes off the top, the app has been closed.
3. Repeat this process to close all applications then tap the small ‘home screen’ preview to return to the home screen.
iOS 6 and earlier
1. Double tap the Home button on the iPad/iPhone. This brings up the Parked Apps bar with all of the currently ‘parked’ apps listed.
4. Press the Home button twice to return to the normal home screen.
Rebooting the iPad/iPhone
- Press and hold down the Home and Power buttons.
- Keep holding them until the device shuts down (ignore the Power Off slider and keep holding the buttons, the device will shut down a couple of seconds later).
Note: Release the Home button as soon as the device powers down, as holding down the home button during reboot if you have a USB cable plugged in to your iPad causes it to go in to recovery mode.
- Press and hold the Power button until the device starts to reboot.
This clears out the device memory and gives applications a more stable base to run from.
