Take the Reins of your AI. Reins connects to your Ollama, LM Studio or any OpenAI-compatible server and runs local AI models directly on-device. It brings powerful AI models like Gemma, Qwen, Llama and more to your iPhone and iPad — with tools, web search, and full control over every conversation. No login. No data collection. PLUG-n-PLAY Either connect to your Ollama, LM Studio or OpenAI-compatible server, or run models on-device. Reins just works, keeps everything private, every chat stays yours. TOOLS & WEB SEARCH Go beyond chat. Reins gives models the ability to search the web, fetch pages, calculate and reason across multiple steps — no API key required for web search. FULL MODEL CONTROL Download, switch and manage your models directly from the app. Connect multiple servers, configure API keys and custom headers and switch between them instantly. Access Ollama Cloud when you need it. POWERFUL CHAT Attach images, PDFs, CSVs and text files to any conversation. Enable thinking mode for deeper reasoning when you need it. Branch chats to explore different paths without losing your original thread. Never lose a cut-off response, pick up exactly where it stopped. Export or back up your conversations anytime. FINE-GRAINED CONTROL Set a different system prompt for every conversation. Dial in temperature, context size, max tokens and more for precise control over model behavior. ON DEVICE MODELS Run AI models directly on your iPhone and iPad without any setup. It's powered by MLX to achieve the best performance on Apple Silicon. You can download any MLX model even if it's not listed in the library. Reins also works with Apple Intelligence's on-device Foundation Models. BACKGROUND PROCESSING No need to wait around for complex reasoning, long responses or model downloads. Switch apps or lock your screen and Reins keeps generating in the background. Come back and it'll be waiting for you. (Requires iOS or iPadOS 26.0+) Reins works with your Ollama, LM Studio or OpenAI-compatible server, or runs AI models on-device with no server required. Self-hosted or Ollama Cloud both work too. Privacy Policy: https://getreins.app/privacy Terms of Use: https://getreins.app/terms

About

Button API

Features
Read full description

Button API turns your iPhone or iPad into a physical-like remote control for web services. It is a smart, interactive button for instant HTTP/HTTPS requests, designed specifically for automation, testing, and integrations. The app is built for developers, system administrators, smart home enthusiasts, and QA engineers. It helps you trigger automation scenarios (IoT, Node-RED, Home Assistant), test webhooks, manage server processes, send notifications, or demonstrate API functionality with a single tap. Key Features: Flexible Request Configuration Full control over your requests: support for GET, POST, PUT, PATCH, and DELETE methods. Custom headers and request body. Dynamic templates: automatically insert press timestamps or battery level data into the request body. Complete Interface Customization Button builder: adjust text, shape, size, and colors to suit your needs. Custom graphics: set your own images for normal and pressed states. Screen background: choose a solid color, an image, or a live feed from the device's camera. Control & Stability Prevention of accidental triggers: rate limiting and cooldown modes. Security: restrict access to settings with a 6-digit PIN code. Logging & Data Portability Built-in log: keep track of sent requests, server responses, and errors locally. Export data: save history as CSV or TXT files. Quick setup: import and export configurations to quickly replicate your setup across devices. How It Works Setup takes less than a minute: specify your target URL (endpoint), customize the button's appearance, and send your first request. Button API eliminates the need for writing console scripts or using bulky tools when you need a simple solution: one tap, one action, reliable results.
