From your charging history to your next stop. Kwhit helps EV owners organize charging records and understand running costs. Import supported charging bill screenshots or connect your Tesla to receive charging data automatically. Bring energy, spending, and vehicle information together in one place. AUTOMATIC TESLA CHARGING RECORDS — PRO Connect your Tesla account and complete virtual-key setup to receive charging data automatically. When charging ends, open the reminder to review your record. Battery level and odometer readings can be included when reported by your vehicle. • Follow charging progress on Dynamic Island and your Lock Screen. • Set your home location and electricity rates to identify home charging and estimate its cost. • Choose a flat rate or custom peak/off-peak settings. • Import charging records and fees supplied by Tesla, with billing details added when available. • Use vehicle location to find nearby third-party charging stations, then confirm the station and enter the fee. REDESIGNED REPORTS See charging spending, energy use, mileage, and other ownership expenses together. Pro adds cost, energy and unit-price trends, period comparisons, charging highlights, time-of-day patterns, operator breakdowns, report images, and CSV exports. SMARTER STATION SEARCH Search by operator, station name, or area. Improved matching handles Chinese and English brand names and common spelling mistakes. Explore nearby station details and available prices. Pro recommendations consider your charging habits, distance, and pricing. Planning a trip? Find charging stops along your route. Pro compares driving detours to help you choose a suitable stop. FOR EV OWNERS, WITH OR WITHOUT A TESLA Import supported screenshots or enter records manually. Track charging energy, fees, discounts, mileage, vehicle details, maintenance, insurance, and other ownership expenses. The free plan includes 8 new charging records and 5 ownership-expense entries per month, basic summaries, and nearby station search. Pro removes these entry limits and adds multiple-vehicle management, deeper analysis and exports, AI insights, and iCloud sync. Automatic Tesla recording requires a compatible vehicle and vehicle software, account permissions, and virtual-key setup. Data may be incomplete or delayed; locations and fees may need confirmation. Home charging costs are estimates, not utility bills. Dynamic Island requires a supported iPhone. Station details and prices may vary; check with the charging operator. Kwhit is independently developed and is not an official Tesla app. Pro is an auto-renewing subscription. Prices and billing periods are shown before purchase. Manage or cancel your subscription in your App Store account settings.
