## What is EngineIQ?

Stop guessing. Start diagnosing.

EngineIQ Diagnostic is an AI-powered automotive diagnostic app built to help drivers, DIYers, mobile mechanics, and technicians find problems — not just replace parts.

Most code readers stop at the trouble code. EngineIQ helps you go further.

Enter your vehicle symptoms, diagnostic trouble codes, freeze-frame data, scan notes, repair observations, and test results. EngineIQ Diagnostic analyzes the information and helps rank the most likely problems from most probable to least probable, giving you a smarter path forward before you waste money on random parts.

Whether you are dealing with a check engine light, drivability issue, no-start condition, sensor fault, misfire, fuel problem, electrical concern, or confusing scan data, EngineIQ helps organize the diagnostic process so you know what to check next.

EngineIQ Diagnostic helps you:

• Rank likely causes based on the information you enter
• Follow a step-by-step troubleshooting workflow
• Avoid guessing from codes alone
• Reduce random parts swapping
• Organize symptoms, notes, reports, estimates, and invoices
• Build a clearer diagnostic path before making repair decisions
• Work smarter as a DIYer, driver, mobile mechanic, or technician

EngineIQ is not just another scanner app. It is designed to help you think through the problem, understand possible causes, and follow a structured workflow toward the real issue.

Codes do not always tell the whole story. A DTC trouble code may point you in a direction, but it does not automatically tell you which part failed. EngineIQ Diagnostic helps you combine codes, symptoms, data, and observations into a ranked diagnostic approach.

No more guessing.
No more throwing parts at the car.
No more wondering what to test next.

Start with EngineIQ Free — connect your OBD-II adapter, read and clear codes, and diagnose your first vehicle at no cost. When you're ready for more, EngineIQ Pro unlocks unlimited vehicles, the Tina Diagnostic Assistant, Drive-Test Diagnostics, and the complete diagnostic toolbox — starting at just $4.99/month, or save with $39.99/year. Prefer to pay once? Get EngineIQ Pro Lifetime for $79.99 — one payment, no subscription, diagnose for life.

### 5/5 — Great App!

*2026-08-20*

I actually use this for all my vehicles even my 2001 Goldwing which diagnosed the grinding sound in the engine so it’s pretty darn good.!

### 5/5 — Revolutionary app

*2026-07-23*

Works well, lots of features and options, stands out from the others.

### 5/5 — Revolutionary app

*2026-06-20*

This app stands out from the rest, to have all the features of a professional PC based program in the palm of your hand is crazy! I’m lucky to be one of the first to try it out, I noticed the print button doesn’t do anything so hopefully in the next revision that gets fixed but everything else works, the versatility to add vehicle by name or VIN, to set prices and labor and everything to make into a report for the customer is really neat, at first it’s a lot to look at but it’s all there and extremely helpful!

## Version history (last 5 releases)

### 2.0.6 — 2026-10-10

What's New (2.0.6):
Tina now keeps up with your latest conversations, so she stays focused on the vehicle you're working on and doesn't pull in details from older jobs. Forgot your password? You can now reset it right from the login screen with a code sent to your email. We added a Contact Support button in Settings so you can reach us directly, and moved Terms, Privacy and account options there for easier access. This update also includes stability and memory improvements under the hood for a smoother experience.

### 2.0.5 — 2026-09-30

Tina can see now. Plus pro-grade paperwork.

• Show Tina a photo (Pro). Tap + in Tina's chat to send up to 3 photos: scan tool screens from any brand, freeze frame data, scope readings, parts, leaks or warning lights. Tina reads them, flags what matters and tells you where to test next.
• Cleaner Tina replies. Easier to read at a glance, with key findings highlighted and clear next steps.
• Tina's deep diagnostic now tells you what to expect: about a minute, with a few things to read while she works.
• Professional estimates and invoices. Full shop letterhead, customer and vehicle details, diagnosis, itemized labor and parts, warranty, terms and signature lines.
• Preview before you send. Saving a report, estimate or invoice opens a PDF preview you can zoom in on, then print or send.
• Your Document Defaults (notes, warranty, terms and disclaimer) now appear on estimates and invoices, and clearing a box in Settings really clears it.
• "Save Draft" on invoices is now "Save Invoice," and saving no longer resets a sent or paid invoice to draft.
• Bug fixes and wording improvements.

### 2.0.4 — 2026-09-29

Tina just got smarter.

• Real vehicle data. Tina now checks your exact vehicle against official NHTSA records (VIN details, recalls and owner complaints) before she diagnoses.
• Straight answers. Tina tells you what she looked up and what comes from her own know-how, so you know exactly what you're working with.
• Pro: deeper diagnostics. Multiple codes, intermittent problems, no-code drivability issues and comebacks now get Tina's most advanced reasoning.
• "Check for Recalls" now always shows you a result instead of sometimes appearing to do nothing.
• Full System Scan is now "View Live Data" for clarity.
• Fixed the back button on the Scan Data screen so it returns you to your vehicle.
• Performance and stability improvements.

### 2.0.3 — 2026-09-20

Bug fixes and a smoother UI experience for the user

### 2.0.1 — 2026-09-11

What's New — EngineIQ Pro Pricing Update

Introduced simple, transparent EngineIQ Pro pricing: $4.99/month, $39.99/year (save 33%), or $79.99 one-time for lifetime access — pick whichever fits how you use EngineIQ.
Redesigned the Pro upgrade screen.
Added Lifetime Pro: pay once, unlock EngineIQ Pro forever — no subscription, no renewal, no recurring billing.
EngineIQ Free now clearly includes one vehicle with core OBD-II diagnostics, so every user can experience the app before upgrading.
Improved messaging when a Free user hits a Pro feature (like adding a second vehicle or running Drive-Test Diagnostics) — clearer, more specific explanations of what upgrading unlocks.
General reliability improvements to purchase, restore, and subscription-status handling.
