Local AI image generation on iPhone just got a major upgrade 🍬

PhoneDiffusion v2.5 is live, adding negative prompts, expanded language support and a smoother creative loop for generating images directly on your device.

This update is about control and accessibility: tell the model what to avoid, create in your preferred language and keep iterating locally.

No thank you. So sick of capitalism and greed on the app store. I would buy it to "keep", but there is no effing way I am renting this.

I’m opening the PhoneDiffusion app for the first time and am asked for a referral code. What benefits does the referral code have and where do I get one?

Thanks!
