About

ARStain

Features
Read full description

Create together with ARStain, an AR drawing experience for children and parents. Choose a Bird or Car and place it in the live AR view. Move and resize it to explore. For Birds, move the colorful AR Bird aside to reveal its sketch. The sketch guides your drawing; the color Bird gives you a visual reference. Switch to Draw and make your picture with a finger. Return to AR to check the sketch or color reference, then keep drawing. When you're ready, save your drawing to Photos. The saved image contains only your drawing, not the camera view, AR objects, or app controls. Hummingbird and all Cars are free. A one-time, non-consumable Premium in-app purchase unlocks nine additional Birds; it is not a subscription. If you purchased Premium before, open a locked Bird and choose Restore Purchases.

If you are the kind of person who values privacy and wants to keep your generated images private, our software is the perfect solution for you. Run Stable Diffusion locally! No need to connect to the Internet, guarantee privacy, no ads, unlimited times! It is recommended to use iPhone 14 or above, or iPad/Mac with M2 or higher chip. In order to provide a smoother experience, iOS 17 / MacOS 14 or above is recommended. iOS 16 / MacOS 13 is the lowest supported version. If you use lower chips, the loading time will be longer. iPhone 14 will take about 3 minutes to load the model, but M1 will take about 12 minutes. The generation speed depends on your phone configuration. It takes about 6 seconds for iPhone 14 to generate an image under the default configuration. If you generate multiple times in a row, the phone may overheat and slow down the generation speed. If the generation effect is not good, you can repeat the generation several times to see. It is also recommended to learn prompt skills before you use this App. If you found translation errors or want to add more languages, please contact me via comment or "Developer Website" -> "Support". Note: This app is based on Stable Diffusion 2.1 (SD2.1) and is optimised for speed and compatibility on lower-end devices. For users who have newer devices and want higher-quality output, we also offer a separate app powered by Stable Diffusion XL (SDXL), called "AI Art - Private Diffusion Pro". Each version is designed to serve different performance needs. You can also purchase our bundle to own both apps and switch between them as needed — saving nearly 50% compared to buying separately.
