Naubat vs EV Chargebook

Designed for EV owners who want independent, technically rigorous insight into their battery. Naubat connects to your electric vehicle through a Bluetooth diagnostic dongle and gives you structured access to your battery data. Monitor live battery signals, review your trips and understand how temperature, driving style and energy usage affect your vehicle. Built on professional automotive diagnostic standards, Naubat reads data directly from the vehicle’s diagnostic system — without relying on manufacturer APIs. Requires a Bluetooth Low Energy (BLE) OBD-II dongle.

Every charge. Every penny. Every mile. EV Chargebook is the charging log for your electric car. You note what you charge, and the app works out what it cost, what your car really uses and when you paid too much. For iPhone, iPad and Apple Watch, kept in sync through your iCloud. LOGGED IN SECONDS When you plug in, the app already knows where you are, who you charge with and how you usually do it. EV Chargebook Intelligence fills in charging type, connector, provider, energy and cost, so you only confirm. You can even start straight from your Apple Watch. HONEST NUMBERS Charged isn't consumed. If you like, EV Chargebook separates what the charger metered from what actually reaches the battery, so your consumption matches your car's trip computer. Add cost per kWh and per distance, free charges, AC against DC, and a comparison with a petrol or diesel car. YOUR OWN POWER Charging at home from solar panels? Split every session into solar, home battery and grid. The cost follows automatically, and so does your self-generated share. EVERY COST OF YOUR CAR Insurance, tax, servicing, tyres, leasing and everything else: enter it once and recurring items carry on by themselves. Photograph a receipt and the app reads the amount and date. Together with charging you see what your car really costs per month and per 100 km, with depreciation if you like. TYRES AND TEMPERATURE Note when you fit summer, winter or all-season tyres. EV Chargebook compares consumption at the same temperature, so it measures the tyres rather than the cold, and reminds you to change them in spring and autumn. INTELLIGENCE THAT THINKS AHEAD Every charge gets a score from 0 to 100, every month a score of its own. With Pro, the timeline flags unusually expensive sessions, new records and free opportunities. You don't search, it finds. TRIP LOG WITH ROUTE Log trips with purpose, type and odometer reading. With Pro the app can record the whole route, even in the background, and start recording through a Shortcuts automation as soon as your iPhone connects to your car. Export trips as PDF, CSV or GPX. SHARE WHAT'S WORTH SHOWING After a standout charge the app offers a ready-made image: monthly summary, single charge or trip, light or dark, sized for stories, feed or square. Your location stays out unless you switch it on. TWO DESIGNS Alongside the classic look there's Mosaic: calm tiles, clear numbers, your accent colour. Switch in Settings. YOUR DATA STAYS YOURS No account, no ads. Your data lives on your device and in your iCloud. Automatic backups before every update and every day, with a preview before you restore. PRO Pro adds Intelligence suggestions for every field, the timeline and all reports, unlimited vehicles, full analytics, route recording, total cost per 100 km, CSV export and import, the trip log as PDF, widgets, the Live Activity in the Dynamic Island and six more accent colours. Pro is available monthly, yearly or as a one-off purchase. The monthly and yearly plans start with a 7-day free trial. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
