This app allows you to create interesting shapes using affine transformation. Affine transformation can do translation, rotation and scaling on object's coordinate. We do iterations, and in each iteration we apply the affine transformation on the object (circle, rectangle, star, polygon or line), coloured in gradient. At the end, you may like the result. Have fun.
Arbor AI
Read full descriptionHide full description
Arbor AI is a multimodal AI assistant built for conversations with text and images. ASK WITH AN IMAGE Take a photo or choose an image, then ask Arbor AI to translate text, explain what it sees, summarize the content, or answer follow-up questions about the same image. KEEP THE CONVERSATION GOING Use text and images together in one conversation. Arbor AI keeps the context so you can ask natural follow-up questions instead of starting over each time. PRIVATE CLOUD BY DEFAULT Arbor AI uses its Private Cloud experience by default on supported devices. You can also view the current daily Private Cloud usage status from Settings. OPTIONAL LOCAL AI For users who want an on-device option, Arbor Vision can be downloaded separately. When Local AI is enabled, Arbor Vision provides visual AI processing on your iPhone and can be used offline after the model is installed. SIMPLE MODEL CHOICES There is no model marketplace and no need to enter repository names. Arbor AI keeps the main experience simple, while Local AI remains an optional advanced feature. MULTILINGUAL The app interface supports Traditional Chinese, English, and Japanese. Private Cloud and Local AI availability depend on device capabilities and system configuration.

Verdict
The clearest difference is update cadence: Arbor AI at every 3 weeks against A's every 70 months. A's advantage is iOS requirement (15.6 vs 27.0). On price, ads, in-app purchases and device support there is nothing between them.
