Among all the AI apps I've used for running lightweight models locally on iPhone, **LocalChat stands out as the absolute best**. The interface is clean, intuitive, and beautifully organized — no clutter, no confusion. It supports the **widest variety of models**, from open-source LLMs to vision-language models, and switching between **local and cloud inference** is seamless with just one tap. Even more impressive, it has **multimodal capabilities**, letting users work with text, vision, and more — all from a single app. This is a game-changer for anyone exploring real on-device AI. **Highly recommended**. If you're serious about local AI, **download this app now**.

I've downloaded and tested three AI apps the run directly on your phone, and I've gotten by far the best results from this one! All the apps allow you to download and experiment with different models, but this one has given me the best results right out of the box! Like all AI models, it can make mistakes, but this is the most reliable app I've tried that runs directly on my phone!

Shortcuts integration just works. Connects to my local OpenAI compatible LLM server perfectly. Finally, I have just one app as my go-to AI chat client. Deleted all the others that I’ve bought and tried. THIS is the one.

The free version offers a limited selection of models, while the best ones require a pro upgrade. However, since they don’t develop the models themselves, the app functions the same regardless of which one you use. The only difference is access, which feels like more of a paywall than an added functionalit. It would make more sense if they were offering something unique, but that’s not the case. You also can’t load custom models so you can’t choose one. That’s not in their list.
