DegradeLog

DegradeLog is a mobile + web app that helps EV owners and used-car buyers track battery degradation over time using repeatable, comparable tests. Users run a guided “baseline” routine (same charge level, route, temperature notes) and optionally pull vehicle telemetry via supported APIs/OBD adapters where available. The app normalizes results for weather and driving conditions, then produces a simple health trendline, confidence score, and resale-ready report you can share with a buyer or dealer. It also flags suspicious range drops that may indicate tire issues, alignment, HVAC drain, or a failing module—without pretending it can magically diagnose everything. Reality check: coverage varies by make/model and some OEMs block data access; the app is most accurate when users follow the protocol and can connect telemetry. Monetization is subscription plus one-time “report” purchases for private sales.
