Questions

Where do the prices come from?

From real eBay sold prices. The average uses the card price plus shipping — what the buyer really paid.

Why is the app showing up in colors?

The colors tell you how much to trust the match. Green — it captured a great picture, the match is solid. Yellow — somewhat unsure, so check the card against the picture. Red — it's guessing: a hint only, not a price.

Are Auction and Buy It Now prices mixed together?

No. Auction and Buy It Now are never mixed together. They are shown apart, and each one gets its own average and its own graph.

What does watching a card do?

You mark a card to watch, and the app saves it with the average price at that time. When you look the card up again, it flags a big price move for you.

Does this app set my price for me?

No. The app suggests a price and shows you the numbers. It does not set prices — you set the real price.

How much does it cost?

It is $9.99 a month, or $99.99 a year. You get 7 free days first. One free trial per eBay store.

Can I start another free trial with a different account?

No — the free trial goes with your eBay store, not with one login. One free trial per store, for each app. If your store already had its 7 free days for an app, that app starts as a paid subscription.

How does “Delete all my information” work?

Click the “Delete all my information” button and it asks you twice, to be sure. Then it wipes everything the app has saved and starts empty. It cannot be undone.

Delete all my information wipes everything this app has saved and starts it empty. It asks first. It cannot be undone.

Link my store

Link this app to your own store, so it pulls your information.

Link your store by typing or pasting your store address — for example, https://www.ebay.com/str/yourstorename. This app never asks for your eBay password.

For flipping

When this is on, a raw card's results show a suggested buy price worked backwards from the average sale price, with the math written out under it. It starts off — turn it on if you flip cards.

Selling for cash instead of on eBay? Turn the eBay percentage off. Selling in person, from a local store? Turn shipping off — that won't happen all the time. The buy price figures again with just what's left on, and its math line says what was actually taken off.

Flip cushion: %

The cushion is the room you leave yourself, on top of fees and shipping. It starts at 20% — set it bigger to buy cheaper, smaller to pay a little more.

Card picture guide

The snap-a-picture screen shows a card-shaped frame to line your card up in. It starts on — a great picture is how a lookup earns green.

How to get a great picture

A good picture is how a lookup earns green. Hold the card straight-on, not at an angle. Line the whole card up inside the frame, and fill the frame — closer is better. Use good light, with no glare shining on the card. Take the photo of the front first — the front is the picture the app needs. When your picture comes back, check the card sits inside the frame; if it is crooked or cut off, take it again.

What the colors mean

🟢 Green: it captured a great picture, the match is solid.
🟡 Yellow: somewhat unsure — check the card.
🔴 Red: it's guessing — a hint only, not a price.

YOUR CARD
GOES HERE

Line the card up inside the frame to get a good picture.
Fill the frame — closer is better.
Good light, no glare.

Your photo, shown inside the frame — check the card fills the frame and nothing is cut off. If it looks crooked or cut off, take it again.

Best guess from the photo — check the card before trusting it.

The fields below are pre-filled with a best guess. Fix anything that doesn't match the card in your hand, then look it up.

➕ Photo of back

Photo of back — optional. Add it if you want, for even more accurate information: the back has the card number and the set. The app never requires it — the photo of front is all you need.
