Applin Tester vs Qdrant Viewer

Applin is a framework for making mobile apps. It uses server-driven UI. If you know computer programming, you can use an Applin server library to make an app server, with pages and functions defined in the server's code. Then use the Applin client library for iOS to quickly make an iOS app that connects to your server and displays the pages. Applin Tester embeds the Applin client library for iOS and connects to any Applin server. As you develop your app server, you can use Applin Tester to connect to your server and display your app's pages. Applin Tester also displays Applin demo apps, with links to their source code.

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.
