Hey Product Hunt 👋 I’m the maker of VoltKeep — an iOS app that turns Tesla driving data into automatic trip logs, efficiency insights, and AI-powered recommendations. I built it because Tesla owners generate a lot of useful data every time they drive, but it’s surprisingly hard to review it in a simple, native, privacy-conscious way. VoltKeep does a few things: ⚡ Automatically records every Tesla trip 🗺️ Visualizes routes on Apple Maps, color-coded by speed 🔋 Tracks efficiency, battery trends, and phantom drain 🧠 Uses AI to explain how to improve range 🔐 Encrypts driving data so it can only be decrypted on your iPhone It’s built on Tesla Fleet Telemetry and designed for owners who want useful insights without setting up servers or relying on browser dashboards. The current app UI is Japanese-first, but the experience is visual and available globally. English UI is in progress — and I’d especially love feedback from Tesla owners outside Japan. What would you want to see in a Tesla driving analytics app?
