What is subralabs?
SubraLabs is an independent software development studio that builds iOS apps, web products, and AI-powered tools from concept to launch. Its public work focuses on a practical question many mobile teams face: should a large language model run on-device or in the cloud when it needs to call tools and act autonomously. Through a real iOS application, SubraLabs demonstrates agentic tool calling with both approaches and compares how they perform. On-device models keep data local and can respond without a network round trip, while cloud models offer more capacity but add latency and dependency on connectivity. The studio surfaces these trade-offs, benefits, and limitations so developers can see how each method behaves in an actual app rather than in an isolated benchmark. Because the material is grounded in a working product, it is most useful as a reference for iOS and AI engineers weighing where to run inference for agent features. SubraLabs itself operates as a studio, taking client and in-house projects across mobile, web, and AI from idea through launch.
What is subralabs used for?
iOS and AI developers reference SubraLabs to compare on-device versus cloud LLM agentic tool calling inside a real iOS application.
How much does subralabs cost?
Pros and cons
Pros
• Demonstrates real agentic tool calling inside an actual iOS application • Compares on-device and cloud LLM performance side by side • Highlights the trade-offs and limitations of each approach • Grounded in a working app rather than abstract benchmarks
Cons
• Primarily a demonstration and studio showcase, not a standalone product to buy • Scope is limited to iOS and the studio's own examples • No pricing or self-serve access is published
