Decay Radar

Decay Radar is anti-productivity telemetry for developers who want honesty—not guilt—about how long it has been since they last touched code. Log an optional “code session” when you actually sit down to practice. No line counts. No sprint boards. No assigned tasks. Just a timestamp, an optional focus tag, depth minutes, and a short note if you want one. WHAT YOU GET • Fluency index — a live percentage that cools over time using a half-life you control • Decay curve — visualize how your optional sessions reset the clock and how fluency falls away • Cadence gap — plain-language time since your last anchor • Session log — focus tags (General, Debug, Feature, Reading), notes, and swipe-to-delete history • Insights — projections to 50% and 25% fluency, rolling 7/30-day pulses, median gaps, and comfort-cadence drift • Calibration — tune decay half-life and set a comfort cadence (max days between optional sessions) • Export — share a text digest of your archive when you want a snapshot outside the app PHILOSOPHY Skill maintenance is not a leaderboard. Decay Radar treats “time since last optional session” as signal, not shame. Use it when you care about staying warm—not when you need another task manager. PRIVACY Your pulses stay on device. Decay Radar uses local storage only; no account, no cloud sync, no analytics SDK in this build. WHO IT IS FOR • Developers maintaining side skills between shipping cycles • Anyone returning from a break who wants a gentle decay clock instead of streak pressure • Engineers who prefer a minimal log over yet another habit app Open Radar for the dashboard, Log for pulses, Insight for projections, Decay for calibration. That is the whole loop—small on purpose.
