TangiLM — Run AI Locally on Your iPhone TangiLM is a mobile language model app that lets you run powerful chat and reasoning locally on your iPhone. No account required, no cloud subscription, and no need to send your prompts to remote servers. Download your own GGUF models easily, manage them easily, and chat with full control over what runs on-device. Key Features Offline-first private chat Run your language model locally for everyday conversations, brainstorming, Q&A, and writing. Keep your data on your device to support a more private workflow. Download and manage local models Browse, download, and load your favorite GGUF models from Hugging Face. The app scans your model directory, tracks download progress, and lets you switch models anytime. Optional web search for up-to-date answers When enabled, TangiLM can perform web searches and pull relevant page content to help answer time-sensitive questions. This hybrid approach keeps casual chat fast while still supporting more current information when you choose. Built-in search workflow (analyzing → searching → evaluating → fetching) For improved relevance, the app uses an advanced internal agent loop to refine search queries, decide whether to fetch a page, and combine results into the final context used for generation. Thinking and searching controls If your selected model supports advanced reasoning, you can enable a “thinking” mode for better step-by-step answers. You can also toggle the web search feature per conversation. Fine-tuned performance and stability TangiLM also lets you fine-tune inference parameters for better speed and stability. For newer model releases, the app provides strong compatibility and optimized inference behavior, which helps reduce the likelihood of overheating and crashes commonly seen in other iOS AI tools. Session and history support Your chat sessions are saved automatically so you can continue where you left off. Review messages, edit user content, and keep your workflow organized. Multilingual UI and prompts The interface is localized across multiple languages, and the app supports multilingual prompts for smoother international use. Why TangiLM Whether you’re building a private assistant, experimenting with different models, or asking questions that benefit from fresh web information, TangiLM gives you a practical, flexible toolkit: local speed and privacy by default, with optional online search when you need it.

Verdict

The call

The clearest difference is ads: TangiLM at none against Opus's shown. TangiLM also leads on monetization model (free vs free with in-app purchases) and update cadence (every 8 days vs monthly). Opus's advantage is device support (3 vs 1) and iOS requirement (16.0 vs 18.6). On price and in-app purchases there is nothing between them.
