Teslatlas gives you a clear, native view of your driving and charging history on iPhone, iPad and Mac, imported from a source you host yourself. Try the built-in offline demo before connecting your own source. YOUR HISTORY, MADE CLEAR • Browse drives with route, distance, energy and available costs • Review charging sessions, energy, prices and charging curves • Explore battery-health estimates, efficiency trends and parked drain • Build trips, compare periods and export selected data • Check source and local-database readiness LOCAL RECORDS, USEFUL OFFLINE Connect your separately configured source and import your history. Prepared local records can then be browsed offline. Source updates, purchases and restore, Apple map assets, eligible weather requests and external links need network access. Feature access and available source coverage still apply. READ-ONLY SOURCE IMPORT Teslatlas does not send vehicle commands or write back to your configured source. History is stored and analysed on your device. Teslatlas does not operate a vehicle-history relay or upload product analytics to Magrathean. SIRI, SHORTCUTS AND OPTIONAL AI Ask supported questions about locally recorded drives, consumption, charging and costs with Siri and Shortcuts. Numeric answers read local facts without preparing an AI model. Missing values and estimates remain identified. Available answers depend on your imported records and permitted history window. Optional AI explanations (experimental-beta) require supported Apple hardware, software and language, and explicit in-app consent. WEATHER WHEN YOU OPEN A DRIVE Eligible Drive details can request weather context from Apple when opened and cache the result locally. This does not reconstruct weather for old drives. The offline demo does not request weather. 30 DAYS FREE. ONE-TIME FULL ACCESS. Browse your last 30 days at no charge, with no trial countdown or automatic paid conversion. A one-time Full Access purchase expands the history window to a full year (365 days), where records are available from your source. The App Store shows your local price. Restore purchases from Settings. Previously verified access can be used offline while its local entitlement cache remains valid. WHAT YOU NEED The built-in demo uses fictional records and needs no source account. To import your own history, connect a self-hosted TeslaMate PostgreSQL database or a MyTeslaMate account that your device can reach. Source hosting is separate from Teslatlas. The demo does not provide real-data Siri answers. Battery-health, energy and cost estimates are informational, not diagnostic, repair or warranty advice. Teslatlas is independent and is not made, endorsed or supported by Tesla or MyTeslaMate.
