Identify mold and know if it's dangerous. Mold Ace uses AI to tell toxic Stachybotrys from harmless Cladosporium, so you know whether to clean it yourself or call a professional. Save your scans, add notes, chat with AI, and export a PDF report for your landlord or insurance company. FEATURES • AI Mold Identification Take a photo of any mold, mildew, or household fungus to identify the species. Get scientific and common names, where it grows, why it appeared, and how to remove it safely. Works on bathroom mildew, kitchen mold, ceiling spores, and outdoor mushrooms. • Health Risk Tier Every scan returns a clear risk rating — High, Medium, or Low. You instantly know if you are looking at toxic Stachybotrys, problematic Aspergillus, or harmless surface fungus. Each result tells you when you can clean it yourself and when to call a professional. • PDF Report Export any scan as a formatted PDF with date, location, high-resolution image, and full risk assessment. Useful for landlord disputes, insurance claims, and water damage documentation. • AI Mold Chat Ask follow-up questions about removal, exposure, prevention, allergies, or any mold topic. Revisit past conversations anytime. • Mold History Save every scan with high-quality images, dates, and locations. Track problem areas in your home over time. • Personal Notes & Location Add observations to each scan and tag the room where you found it. The location prints in the PDF header — useful documentation for your landlord or insurer. • Favorites Mark notable scans to find them quickly. Keep your most important findings easily accessible. • Private by Design Your scans stay on your device. No account, no cloud sync, no GPS tracking. Back up your history to a local file anytime, restore it when you change phones. Stop guessing whether mold is dangerous. Mold Ace gives you a clear health-risk rating — and a PDF report when you need to share what you found. There is an optional Premium subscription for unlimited access. The subscription will be charged to your iTunes account upon purchase. Your account will be charged for renewal 24 hours before the current period ends. You can turn off auto-renewal at any time in your Account Settings.

About

Auto AI Diagnostics

Read full description

Your check engine light is on. Now what? Auto AI Diagnostics turns your iPhone into an AI-powered car diagnostic tool. Plug a Bluetooth OBD2 adapter into the port under your dash, tap scan, and AXEL — your AI shop foreman — reads the fault codes straight from your car's computer and explains what's going on in plain English or Spanish: what's happening, how serious it is, whether it's a DIY fix or a shop job, and what to do next. FEATURES: • Real fault codes pulled straight from your car's computer — engine and control modules • Automatic VIN read directly from your vehicle's ECU • AI-powered diagnosis with evidence and an action plan — not just a code definition • Fault code descriptions verified against the web for accuracy • View Conditions: see the mileage, battery voltage, and speed recorded when each fault set • Live engine data — RPM, coolant temp, battery voltage, throttle, and more • Odometer tracking with every scan • Scan history so you can track issues over time • DIY repair guidance and YouTube repair video suggestions for your exact vehicle • Ask AXEL follow-up questions about your specific car • Works with older, pre-2008 (K-line) vehicles too • The entire app in English or Spanish — including AXEL's AI diagnosis. Switch anytime. WHAT YOU NEED: A Bluetooth OBD2 adapter (ELM327-compatible, sold separately). It plugs into the OBD port under the dashboard on the driver's side — and on iPhone there's no pairing needed, the app finds it automatically. Works with most gas-powered cars and light trucks sold since 1996 (OBD2), including many pre-2008 K-line vehicles. Auto AI Diagnostics helps you understand your car and make informed decisions — it's information and guidance, not a substitute for a professional inspection when safety is on the line.
