Use Apple Private Cloud Compute, your API keys, or an OpenAI-compatible endpoint. I built Cumbersome because consumer AI apps kept dumbing things down. Cumbersome is the manual transmission of AI apps: more complex, but with far greater control. WHY I BUILT THIS Consumer AI apps hide the controls I want and lock me into one provider. I wanted direct API access, the freedom to pick and compare models, and to pay providers for what I use. This is the app I use every day, so I pay attention and try to get it right. SUPPORTED PROVIDERS - Apple Private Cloud Compute - ChatGPT / OpenAI - Claude / Anthropic - Gemini / Google AI Studio - OpenRouter multi-provider - Vercel AI Gateway multi-provider - Z.ai - OpenAI-compatible custom endpoints, including Ollama, Azure, LM Studio, Groq, Together, and self-hosted backends WHAT YOU GET - A versatile API client. One app, every major provider and model. - Total control. Pick your model, tune the parameters, switch providers mid-conversation. - Compare models head to head. Stream multiple chats in parallel and let an AI judge pick the best. - Bring your own tools. Local browser use, reasoning, web search, image generation. - Rich, editable conversations. Markdown, LaTeX, code blocks, attachments, edit and export anything. - Private by design. iCloud sync across devices. Nothing saved to our servers. - Native and accessible on iPhone, iPad, and Mac.

LLMster is a fast, private iPhone and iPad client for models running on your LM Studio server (https://lmstudio.ai). Stream replies, reasoning, tool activity, and image-based conversations from the models you host—in an app designed to feel at home on iOS. Private by design LLMster connects directly to the server you choose. There’s no LLMster account, telemetry, hosted chat service, or cloud relay in the middle. Your conversation library stays on your device, while model context stays with your configured server. External integrations run only when you choose to enable them. Your models, wherever you run them Keep your models on the machine built for them: a workstation, home server, or always-on computer. Run the LM Studio desktop app or LM Studio’s headless daemon, point LLMster at the host, and start chatting. No companion desktop client is required. Choose the right model without leaving the conversation: • Search or sort by name, size, or format, then pin favorites • See which models support vision, reasoning, or tool calls • Change models without starting a new chat Organized from the start Search chats by title, model, or folder. Browse recent conversations across every folder, then organize, rename, pin, or duplicate important threads. Move and protect your chats Share individual conversations as .llmster files and import them on another device while preserving messages, images, reasoning, tool history, and chat settings. Back up and restore your entire local chat library—including folders, pins, drafts, and attachments—with optional password protection. Backups do not include server addresses, authentication keys, or app-wide settings. LLMster also verifies transferred response context against your configured LM Studio server before continuing a chat. Vision, direct to your server Attach up to four screenshots, photos, or scanned pages to a message and send them to a compatible vision model. LLMster resizes and compresses images on your device before sending them, so the originals remain with you. Open any attachment and pinch to zoom when you need to inspect the details. Hands-free voice chat Talk naturally using on-device speech recognition and text-to-speech. Audio stays on your device; only the resulting text is sent to your configured server. Natural turn-taking and subtle haptics keep the conversation moving without touching the screen. Control each conversation Every chat can have its own: • Integrations already configured in LM Studio • Custom system prompt • Tool-call visibility • Live reasoning preference Stream reasoning as Markdown while the model works, or keep the interface quiet with a compact Thinking indicator and open the completed reasoning when you want it. Control response auto-scrolling, and choose System, Light, or Dark appearance with your preferred accent color. Rich responses, as they arrive LLMster renders streaming Markdown smoothly, including syntax-highlighted code with copy controls, inline and block math, tables, links, lists, and more. Export or share transcripts with their original Markdown intact. Keep going while you move on Run LM Studio on a workstation or headless server and connect from your phone. With Tailscale on both devices, you can keep chatting over cellular or another Wi-Fi network while your models run at home. Setup instructions are available at https://llmster.app/support

Verdict
The clearest difference is in-app purchases: LLMster at none against Cumbersome's 2. LLMster also leads on review sentiment (100% vs 88%). Cumbersome's advantage is ratings volume (100 vs 3) and update cadence (every 4 days vs every 10 days). On price, rating, ads and device support there is nothing between them.
