Carb Goblin
A local-first Android fueling tracker for endurance activities where execution matters.
Carb Goblin records timestamped fueling and note events during endurance activities, compares actual intake against hourly carb, fluid, and sodium targets, and exports a Markdown activity log for later analysis.
The app is meant to feel like a small scientific instrument panel rather than a coach.
Why it exists
During an activity, fueling decisions are often made quickly. Carb Goblin keeps quick-access items large and touch-friendly, shows current-hour progress, and preserves the timeline for later review.
