Tezlo vs TezLab · Tessie
TezLab and Tessie are great at logging your Tesla. Tezlo covers the core toolkit - battery health, Sentry log, mileage, widgets, a second car - and adds what a logging app was never built for: Genie, an assistant that talks, a Send to Tesla you can say out loud, and a local owner community. Keep your logger. Add Genie.
