Zolt: Tesla Companion App

Zolt is a secure, lightweight, and completely free companion app built specifically for Tesla owners who want clear, fast insights into their vehicle's telemetry, battery health, and charging statistics.

Say goodbye to heavy, cluttered user interfaces and expensive monthly subscriptions. Zolt is designed natively for Android to deliver a fast, responsive, and secure utility dashboard to optimize your EV ownership experience.

KEY FEATURES INCLUDE:

⚡ REAL-TIME TELEMETRY
Track speed, power output, climate states, and live vehicle diagnostics. Monitor your car's physical system performance at a glance with zero lag.

🔋 BATTERY HEALTH & DEGRADATION
Watch your vehicle's maximum capacity and battery health trends over time. Identify battery degradation metrics using historical charging logs and tracking tools.

💰 DETAILED CHARGING LOGS
Accurately calculate your total driving costs. Log every home or public charging session, track energy usage, and understand your exact utility spending.

📉 DEEP SLEEP & NO PHANTOM DRAIN
We care about your car's range. Zolt is built with an optimized background synchronization protocol that only queries your car's status when the vehicle is already awake or driving. Once parked, the app stops polling to let your Tesla enter "Deep Sleep" mode naturally.

🔒 SECURE, OFFICIAL LOGIN (OAUTH)
Your security is our absolute priority. Zolt operates strictly using Tesla's official Fleet API and secure OAuth login flow.
• Your Tesla password never touches our servers.
• The app only requests secure, scoped access tokens directly from Tesla.
• We do not store or keep personal login credentials.
