The shop-floor toolkit for aging Toyota, Honda & Ford hybrids: five calculators, a full service checklist, 60 quizzes, and the complete guide — all 100% offline. Hybrid Service Essentials is a shop-floor toolkit for diagnosing and repairing aging hybrid vehicles — built for independent technicians and hands-on DIYers working on out-of-warranty Toyota, Honda, and Ford hybrids. This is a TOOL app, not just a book. Five interactive calculators turn the hard calls into fast, confident answers: • HV Battery Health Estimator — enter module readings and get an estimated pack health with a clear rebuild-vs-replace verdict. • Repair Cost Estimator — compare rebuild, remanufactured, and dealer options with a return-on-value read. • Regen Brake Wear — predict pad life from mileage and duty cycle, and know when to inspect rotors. • Inverter Coolant Service — track the 100k-mile interval and follow the bleed procedure step by step. • 12V Battery Check — convert resting voltage to state of charge and get a replace-or-keep call. Everything works fully offline. No account. No subscription. No ads. MORE THAN CALCULATORS • Service Checklist — a repeatable, phase-by-phase hybrid job from intake to road test, with progress saved automatically. • Quizzes — 60 questions across 12 chapters with instant feedback and plain-language explanations. • Glossary — quick definitions for the codes, components, and acronyms you meet on the bench. • Progress & Achievements — track reading, service, and quiz progress and unlock badges as you go. THE FULL REFERENCE, INCLUDED As a bonus, the complete illustrated guide is bundled inside — every chapter and diagram, readable offline with adjustable text size, bookmarks, and resume. BUILT FOR THE BAY • iPhone and iPad • 100% offline — nothing leaves your device • No sign-in, no tracking, no ads Whether you're quoting a high-voltage battery, chasing a no-start, or deciding rebuild vs replace, Hybrid Service Essentials gives you the numbers and the procedures to work faster and quote with confidence.
