Common questions

What are credits, and when are they used?

You get 3 free credits a day. The grade at the end of a Sort or Count drill, and Auto sort after a scan, each use one. Practicing itself never costs a credit.

I bought the unlock and switched phones. What now?

Sign in to the App Store on the new phone with the same Apple account, open the purchase sheet and tap "Already bought? Restore". No second payment.

The scanner misread a card

On the review screen, tap that card's tag and correct it. If a card wasn't seen, tap "add them" in the "N missing" line to add it. Then sort as usual.

Our local rules are different

Home → More → Rules. Choose what may be returned as tribute and how big a bomb can get, and sorting, grading and counting all follow.

Are my photos uploaded?

No. Recognition runs on your phone. Photos never leave your device and are not saved outside the app.

How do I delete my data?

Drill records and scores live only on your phone. Deleting the app clears everything. We hold no data of yours.
