Every Local AI App for iPhone, Compared (2026)

Solair AI — Best Overall Local AI for iPhone

Solair AI runs 60+ models from Qwen, Llama, Mistral, Gemma, and DeepSeek on your iPhone's Neural Engine using Apple's MLX framework. It's the only local AI app on iPhone that offers voice conversations, vision AI, and private health intelligence — analyzing 15+ Apple HealthKit metrics (steps, heart rate, sleep stages, HRV, VO2 max, workouts, blood pressure, and more) entirely on-device.

The Private Space feature is unique: because everything is 100% on-device with zero data collection, Solair is the only AI safe enough for deeply personal conversations — anxiety, journaling, emotional support — with built-in prompts to get you started. Other standout features include Auto Mode (picks the best model per task), conversation forking, personal memory, document analysis, private web search, and a duress code for emergency data wipe. If you need more power, the Remote Server feature connects to your own LLM servers via Tailscale VPN for 70B+ models. Free, no account, no subscription.

PocketPal AI — Best Open-Source Local AI

PocketPal AI is a free, open-source app for running GGUF models from HuggingFace locally on your iPhone. It supports a wide range of models and includes benchmarking tools. The open-source nature means full transparency. Available on both iOS and Android. The trade-off: no voice mode, no vision AI, no health data access. It's a solid model runner, but lacks the features that make Solair a full assistant.

Locally AI — Clean Local AI Chat

Locally AI runs Llama, Gemma, Qwen, DeepSeek and other models directly on your iPhone, iPad, and Mac. Clean interface, easy model management. Works across Apple devices. Free. No voice, no vision, no health data — it focuses on doing text chat well without the extra features.

Private LLM — Simple Paid Offline Chat

Private LLM offers basic offline AI chat on iPhone and iPad. Smaller selection of models, clean interface, straightforward experience. It does one thing — on-device text chat — and does it well. The main limitation: it's a paid app with fewer features and models than free alternatives like Solair AI.

Enclave AI — Local AI with On-Device Voice

Enclave AI is a private local AI assistant for iPhone and Mac with on-device voice recognition and synthesis. Supports Llama, Qwen, SmolLM, and Gemma models. The voice feature is a differentiator among local AI apps. Premium pricing model. Less model variety than Solair, no health data access.

Opal AI — Basic Offline AI Chat

Opal AI runs MLX-compatible models locally on your iPhone. Clean SwiftUI interface, works fully offline after downloading models. Curated model selection from HuggingFace with pausable/resumable downloads. One-time purchase with no ads or tracking. Lacks voice mode, vision AI, health intelligence, and the advanced features found in Solair.

MLC Chat — Open-Source Mobile AI

MLC Chat uses the Machine Learning Compilation framework to run models on iOS and Android. Fully open-source. More of a technical project than a consumer-ready app — the interface is basic and setup requires some technical comfort. Useful if you want to understand the underlying technology or contribute to the project.

OneLLM — Local AI with Ollama Integration

OneLLM combines local on-device models with the ability to connect to an Ollama server running on your computer. Also includes offline OCR and voice-to-text transcription. Useful as a bridge between mobile and desktop local AI. Supports Llama, Gemma, Qwen, and Mistral models locally. Free and Pro versions available.
