Catalytic converter pricing for iPhone
What’s it worth? One tap.
Enter the converter code — CatXapp shows the live buy price instantly. No more guessing at the scale.
20,000+ converter codes, one search.
Type the whole code, or just the letters you can still read if the stamp is rusty. CatXapp finds the matches. Check it is the right one before you pay. GM, Toyota, Diesel, Ford, and more.
Real-time metal prices, in your pocket.
Platinum, palladium, and rhodium spot prices — refresh on tap so every quote reflects today’s market.
Build the buy. Send the invoice.
Add cats to a cart. No code on it? Add it yourself — brand, price, and how many. Leave the brand blank and it shows as Unknown. If a cat is damaged, lower the price. Then make a one-page invoice: how many catalytic converters and the total. The seller signs with a finger. Preview it first, then save and share the PDF.
Pro feature
Your company. Your sellers.
Save your company name and the people you buy from. The invoice shows your company as Issued by and the seller on the other side. Old invoices stay in the app, so you can open or share them again.

FAQ
What is CatXapp?
An iPhone app for professional buyers. Look up a full code or the part you can still read, see live metal prices, and on Pro save clients and send a signed invoice.
How do prices update?
Catalog prices adjust with live platinum, palladium, and rhodium spots. Tap refresh on the market strip for the latest.
Essential vs Pro?
Free: 5 lookups a week. Essential: unlimited lookup and live metal prices. Pro: cart, margin, saved loads, clients, and one-page invoices with a finger signature. You can see Cart and Clients on any plan. Pro is what lets you use them.
Is there a free trial?
Yes. Download free and get 5 code lookups per week with no account. Pro monthly also includes a 7-day free trial via the App Store. Cancel in Settings → Apple Account → Subscriptions.
What if the converter has no code?
On Pro, tap + in the cart and type a brand, price, and how many. If you leave the brand blank, the cart shows Unknown. These rows keep the price you typed.
What is on the invoice?
One page. Your company, the seller, how many catalytic converters, and the total price. Not a list of every code. You can add a finger signature, preview it before saving, and open it again from Invoices.
Android?
iPhone only for now — requires iOS 17 or later.
Buy like a professional.
Look up the code, even if it is rusty. On Pro, finish with a signed invoice.
