Who it is for

Car owners and DIY mechanics who want to understand the job, read the estimate, and know what to ask at the counter — and a place to keep cars, logs, codes, parts, and notes.

How it works

  1. Buy once and install. Open the app in your browser and add it to your home screen: Safari on iPhone, or Android, or PC.
  2. Save your car. Type in year, make, model, engine and transmission, or decode it from your VIN.
  3. Go in prepared. Run the checks, read the estimate, and bring your Shop Sheet to the counter.

One wrong part or wasted bay hour costs more than $19.

See it on your phone

Save the car once. Research the problem, look up codes, read the estimate, compare prices, check recalls, and keep each repair and its warranty on file, so you can make a smarter call before you pay for a repair or DIY it.

What it is not

Not a scan tool — it doesn't plug into your car. Not a substitute for a technician — a qualified tech still does the diagnosis and the work. Not a subscription — you pay $19 once. Not an App Store app — it installs from your browser.

FAQ

Can I try it first?
Yes. The estimate check is free at app.jetisys.com/check. Type in the lines from a shop quote and get the questions to ask. No key, no account.
Is this a subscription?
No. It's $19 one time, with no renewals and no account.
Does it work offline?
Yes, after install. Repair checks, the estimate reader, your Garage and logs, and the code and parts lookups all work without a connection. Recalls and complaints come from NHTSA, so checking for new ones needs a connection.
Does it work on iPhone?
Yes. Open it in Safari and add it to your home screen — not the in-app browser in TikTok, Instagram, or Facebook. It also works on Android and PC.
How many devices can I use?
Up to 3 devices on one license, for example your phone, a second phone and a computer. Hit the max? Reply to your Gumroad receipt.
Where does my data go?
Nowhere. It stays on your device. There's no account and there are no ads. Use Backup and Restore to keep a copy or move to a new phone.
Is it a scan tool?
No. It doesn't connect to your car. It helps you understand the problem, read the estimate and know what to ask. It's not a substitute for a technician.
Where is my license key?
Your license key is emailed to you right after purchase by LicenseSeat (our license service). Check spam/promotions. Can't find it? Go to jetisys.com/key, enter the email you bought with, and you'll get a link to your key. One purchase unlocks up to 3 devices. Paste the key in the app to unlock. Trouble? Email support@jetisys.com.
Can I share the app link?
No. Personal license. Do not share your license key or the private app link.
What if it's not for me?
