Ampio

Ampio is a simple, offline-first EV charging tracker for drivers without a companion app. Start charging, walk away, and still know when your battery will be ready. Many EVs don’t provide real-time charging updates on your phone. Ampio fills that gap by giving you a smart estimate of charging progress and remaining time, fully offline. Key Features: - Track charging without internet - Save vehicles with battery capacity - Save chargers with power (kW) - Set current and target battery levels - Estimate charging time and progress - Monitor percentage and remaining time - View session history and details - Resume active charging after app restart Built for simplicity: No accounts. No syncing. No distractions. Just a clean, focused tool that works when you need it. Important: Ampio provides estimated charging progress, not real-time data from your vehicle. Privacy: No login required. No personal data collected. All data stays on your device. Who it’s for: EV drivers without a companion app, users who want quick charging estimates, and anyone who prefers simple offline tools.
