Heart Juice
A local-first Android activity logger that calculates heartbeats, estimated blood pumped, and beats per mile.
Heart Juice helps make the physical work of intentional activity more tangible.
The app lets a user manually enter activity type, distance, duration, average heart rate, notes, and tags. From those inputs, it calculates total heartbeats, estimated blood pumped, and beats per mile.
Why it exists
Heart Juice is meant to feel factual, fast, and lightly playful. It is not a full fitness tracker, training planner, or social exercise app.
