PhoneDiffusion
#1 Local iOS AI Image Generator: Free, Unlimited & Offline
PhoneDiffusion brings Stable Diffusion to iPhone without the usual cloud workflow. Generate images locally on supported devices, keep prompts and outputs on-device, and save everything in a private local gallery. The app routes each phone to a curated launch model - either SD 1.5 or SDXL. Pro adds premium curated models plus manual CFG, step and batch controls.
Hi Product Hunt, I’m Rok Bozic, Co-Founder of PhoneDiffusion.
I built PhoneDiffusion with Rok Gregoric because most AI image apps still depend on cloud generation. That is convenient, but it also means prompts, experiments, and unfinished ideas usually leave your device.
PhoneDiffusion is my attempt at a more private iPhone-native creative workflow: choose a model, pick a style, write a prompt, and generate with Stable Diffusion locally on supported iPhones. Your prompts, generated images, render history, and downloaded model files stay on-device unless you choose to export or share something.
The hardest part was making the product honest about mobile tradeoffs. Instead of pretending every iPhone should run the same huge model, PhoneDiffusion routes supported hardware across curated launch models: SD 1.5 or SDXL. The free tier includes a local base model and standard controls. Pro unlocks premium curated models plus manual CFG, diffusion step, and batch controls.
I’d love feedback from people who care about private AI tools, Core ML, or local creative workflows:
- Which model or style would you want next?
- What controls should stay simple, and what should be Pro?
- What would make on-device generation feel more trustworthy?
Thanks for taking a look. Let me know if you try it out, I ready every comment and feedback!
This is such a cool launch - running Stable Diffusion fully on-device on an iPhone is so impressive, and privacy-first is so refreshing when everything hits a cloud GPU these days. Love that it actually works in airplane mode.
Curious: how do you handle the model selection for different iPhone hardware? Is it a hard cutoff (e.g. A17 Pro gets SDXL, older chips get SD 1.5), or is there some dynamic profiling that figures out what the device can handle? And are you planning to let power users sideload their own fine-tuned models at some point?
