DrillLedger

DrillLedger is a mobile + web app (traditional + AI) that forces deliberate practice to be specific, measurable, and reviewable. Instead of vague goals like “practice guitar,” users create drills with a clear metric (BPM, accuracy %, time-to-solve, error count) and a short constraint (e.g., “left hand only,” “no backspace,” “slow tempo”). The app schedules drills in tiny blocks, captures results fast, and plots progress with brutally simple charts. The AI layer helps users design better drills, spot plateaus (e.g., too hard, too easy, too repetitive), and suggest the next constraint or progression based on their data—not motivational fluff. It also supports quick “post-rep notes” and tags to identify recurring mistakes. The core value is accountability to the process: you can’t hide behind time spent; you see performance change (or not).
