Question: I'm looking for an app that can generate images from text prompts on my iOS device, do you know of any such app?

One top pick is Avolo, an offline, professional-level text-to-image AI client that doesn't need a subscription. It's got a lot of controls, including AI text-to-image generation, texture mode, AI upscaling and a prompt enhancer. Avolo runs on Apple Silicon and Intel Macs, and it doesn't collect data.

Another top contender is Draw Things, built for iOS and iPadOS. It uses Stable Diffusion models for fast generation and comes with a rich editing pipeline with tools like inpainting masks, outpainting and adjustable controls. It's private since it runs offline, and it supports multiple models for different styles.

If you're looking for a standalone, free app, check out DiffusionBee. It uses Stable Diffusion to generate AI art on your device without any cloud-based services. DiffusionBee can generate text-to-image art, generative fill and video, and since it runs offline, it handles your data privately. It's good for people who want to combine AI with their own creativity.
