A workout tracker that doesn’t interrupt your training
What it does
Most workout trackers felt too heavy for actual gym sessions. Too many taps. Too much friction. Too many features while lifting.

No ads. No extra paywalls.

We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
