How Card Rainbow works

A step-by-step tour of the real app, from your first rainbow to sharing your want list with friends.

Screenshots are from the real app using real cards from the built-in checklists. Prices and values shown are example data.

Pick a year, a set and a driver

Tap Browse sets to open the built-in NASCAR checklists: Panini from 2017 to 2026 and Press Pass from 2009 to 2015 (93 releases). Choose a year, then a release, then a subset like Base or Optic.

Each subset shows its parallels and print runs up front, then the full card list. Tap a driver to start their rainbow.

Or just search a driver

Type a name in Search a driver in all sets to see every card that driver has across every release, with how many parallels each one has.

Cards you already track show a Tracking badge with your count, so you never start the same rainbow twice.

Open a rainbow and check off parallels

Base and every listed parallel are added for you, each with its print run (like /199, /10 or 1/1) and a color swatch.

Tick the box on each card you own. Owned cards turn green, and the ring at the top updates right away. This 2024 Prizm Chase Elliott #68 is 17 of 23, or 74%.

Log what you paid and what it's worth

Tap any parallel to add the price paid, the current value and the date you checked it, plus a source and notes.

Not sure what it's worth? Tap eBay sold comps to open recent sold listings for that exact card. You can also bulk-update values from a file.

See exactly what's missing

Unchecked cards stand out, so you can see at a glance which parallels you still need, like this Carson Hocevar 2025 Donruss #57 still missing Lime Green /199, Artist Proof /25 and Mojo /25.

Each rainbow shows Paid, Value and your Gain/Loss across the cards you own.

Progress rings and your collection value

The home screen lists all your rainbows with a progress ring and bar for each, showing the percent complete and how many you own.

At the top you get your totals: number of rainbows, cards owned, and the estimated value of your whole collection. Filter the list to jump to any rainbow.

Pick a username and share with friends

Set a username in Account settings, then open the Friends tab (🤝). Search a friend by @username, or add their email, and tap Share.

Friends can see what you have and need but can't change anything. Lists shared with you appear under Shared with me. Remove someone any time.

Tips

Little things that make the chase easier.

Start with base

Check off the base and the cheap unnumbered parallels first. Seeing the ring move keeps you going.

Update values before a show

Use eBay sold comps on the cards you plan to buy or trade so you know a fair price.

Share your want list

Send friends your username so they can turn on Need only and spot your cards for you.

Card not in the checklists?

Tap + to build a custom rainbow for any card or sport, or use a quick-add template like Prizm or Optic.

Install it on your phone

Add it to your home screen so it opens fast and works with no signal.

Back up now and then

Your lists sync to your account, but an exported JSON file is a nice extra copy.
