Get your binder ready for offline

Offline access is most useful when you know what was saved before you lose the connection. A card-show venue is an awkward place to discover that you have the collection record but not the image or price evidence you wanted.

Prepare while connected

Open the binder you plan to take and use Prepare offline. Download the available owned and wanted card data, images and saved pricing information. Add relevant sets when you need more reference material, rather than assuming the full catalog lives on the phone.

Keep the app open while preparation finishes. A saved collection and a complete image library are different things, so inspect the result instead of treating the first successful download as proof that everything is ready.

Verify the coverage

Use Verify saved data and read the report. Look separately at cards, images, finish prices, asking records and sold records. Partial coverage means one or more parts are missing. Unknown download size or absent evidence should stay visible as a limit.

Reopen the app offline before the trip. Try the binder and the particular wants you expect to check. Browser storage can be cleared or evicted, so a successful preparation on an earlier occasion is not a permanent promise.

Use saved evidence as saved evidence

Last-known prices can be useful context, but they are not live quotes. Check their age and do not treat an offline chart as a current market feed. Cards or images that were not saved still need a connection.

Collection edits made offline queue for later sync. When you reconnect, let synchronization finish and check the result before repeating an edit or switching devices for the same task.

Keep the plan practical

Charge the phone, make the hunting list specific and verify again before an important event. Preparation should give you a reliable reference for your day, with the limits visible before they matter.
