Qdrant Viewer is a client app for connecting directly from your iPhone to vector databases hosted either self-hosted or on Qdrant Cloud, allowing you to inspect collections and perform semantic searches. Key Features: - Built-in Demo Environment: Immediately try vector search with approximately 30,000 MeSH (Medical Subject Headings) vectors, with no configuration required. - Flexible Connection Settings: Supports connection via REST API, including authentication with api-key, Bearer tokens, and custom headers. - Collection Information Display: View the number of points, segments, vector dimensions, and distance function. Alias names are prioritized if set. - Semantic Search: Perform vector searches using natural language. Adjust the number of results and score threshold for each search. - Flexible Result Display: Select and list any field within the payload (supports nested structures). Detailed inspection in JSON format is also available. - 3D Visualization: Project search results into a three-dimensional space to visually explore the distance relationships between vectors. - Multiple Embedding Engines: Supports Qdrant Built-in, OpenAI, Google, Hugging Face, Cohere, and custom APIs. - Data Source: Uses MeSH (U.S. National Library of Medicine, public domain) as demo data. The embedding model is intfloat/multilingual-e5-small, licensed under the MIT License.

Doom Coder sends a notification to your iPhone and iPad the moment your AI coding agents finish, fail, or stop to ask for approval — so you can start a long run, walk away, and trust your phone to call you back. It pairs with the free Doom Coder app for Mac, which watches your agents and keeps your Mac awake while they work. When an agent needs you, the alert reaches your phone in seconds. WORKS WITH YOUR AGENTS Doom Coder understands the events from Claude Code, Cursor, VS Code Copilot, Copilot CLI, Windsurf, Codex CLI, and opencode. You choose exactly which events alert you — completed, failed, waiting for approval, waiting for input — and mute the rest. USEFUL THE SECOND YOU OPEN IT No account. No sign-in. No Mac required to get started. • Prompts — A prompt refiner, not a chatbot. Type a rough request and get back a clean, structured prompt you can paste straight into your agent. Keep refining over follow-up turns, and pull from a built-in library of developer prompts grouped by Refactor, Tests, Debug, Review, Explain, Git, Docs, and Scaffold. • Notes — On-device notes with checklists, reminders, pinning, and search. Turn any note into a prompt with one tap. • Dashboard — Once you pair a Mac, see every agent's live status and drive the Mac's keep-awake controls from your phone. PRIVATE BY DESIGN No servers. No analytics. No tracking. Everything you write stays on your device. When you pair a Mac, sync happens only through your own private iCloud account using Apple CloudKit — your data is never visible to us or anyone else. ON-DEVICE OR BRING YOUR OWN KEY The prompt refiner runs on Apple Intelligence entirely on your device, so nothing leaves your phone. Prefer your own model? Add an OpenAI or Anthropic API key — it is stored only in your device's Keychain, and only the text you choose to enhance is ever sent. Enhancing is always optional. BUILT FOR iOS 26 AND iPadOS 26 A native interface with the system Liquid Glass design, a macOS-style sidebar on iPad, and time-sensitive notifications that reach you even through Focus. Doom Coder is open source. Source, documentation, and support: github.com/katipally/Doom-Coder

Verdict
The clearest difference is update cadence: Qdrant Viewer at daily against Doom Coder's weekly. Qdrant Viewer also leads on iOS requirement (17.6 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
