Modwise

The App For Car Enthusiasts

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

AI-powered car diagnosis and mod planning, running entirely on your iPhone. Track builds, log maintenance, and get real answers — private by design. Modwise is the garage companion for anyone tracking, maintaining, or modifying their car. YOUR GARAGE, ORGANIZED Add every vehicle you own or build, with make, model, year, mileage, and baseline horsepower and torque. See your mods, maintenance history, and next steps in one place — no more spreadsheets or notes scattered across apps. YOUR AI MECHANIC Describe a noise, warning light, or symptom and get a real diagnosis — powered entirely by on-device AI running right on your iPhone. Nothing you type is sent to a server or a third party; the model runs locally, so your questions stay yours. PLAN YOUR NEXT BUILD Tell Modwise your budget, timeline, and goals, and get an AI-generated modification plan ordered by what to install first. Add steps to your build map, track estimated cost and hours, and check things off as you install them. MAINTENANCE, HANDLED Log oil changes, tire rotations, brake work, and everything else. Modwise surfaces what's coming up next so nothing slips through the cracks. HOW-TO GUIDES Step-by-step reference guides for common DIY procedures, built right into the app. PRIVATE BY DESIGN Your data lives in your own iCloud account, synced only across your own devices — Modwise has no company servers and no way to see your data even if it wanted to. AI diagnosis and recommendations run entirely on-device using Apple Intelligence, not a cloud AI service. No ads, no tracking, no analytics. SIGN IN YOUR WAY Use Sign in with Apple, or create a fully local account with just an email and password — your choice. MODWISE PRO Free accounts get a handful of AI diagnoses each month. Modwise Pro unlocks unlimited AI diagnoses and mod recommendations for $9.99/month or $59.99/year, with a 3-day free trial. Cancel anytime in your Apple ID subscription settings. Modwise is a tool to help you understand and plan your build — always verify safety-critical work (brakes, suspension, fuel systems) with a qualified professional.
