We do not have a native app from an app store, but we do have a web app.  

To install the webs app on your phone, follow the directions here.  The app looks and runs like a regular app.

We are no longer recording "manual only" prices on modern consoles like Switch, PS4, and Xbox One.  

We do record prices on 3DS games because some of them do have manuals.  

I would love to get a list of games without manuals so we can eliminate those manual only prices and mark them in our "item details" sections as being games without manuals.

Any idea where to get such a list?  Or how to tell which games didn't have manuals originally?

We have the console option on the site:

But there are no games yet.  A user said they would help us add these missing games so hopefully they are added soon.

Thanks for the email. We’ve decided to stop tracking new console bundles, unless the console itself is unique. Once these are opened they are basically the same thing as a regular console with the game downloaded. That makes it very difficult to find prices for these exact versions.

I hope you can understand. Thank you

Sorry for any problems.  Can you take a screen shot of the page you are on and where you go when you click the link?  This will help me address this issue.

Can you elaborate on this a bit more?  The UPC scanner should take you directly to a game page that matches that UPC.  On every game page there is a "+collection" button in blue.  

What do you have in mind that is different than this?

CLosing.  Duplicate of this:

I saw this and I can see why it is useful.  I do hope to add something like this in the future.  The timing will depend on the vote totals vs other features and the development time to implement.
