Slabbie works with the Slabbie printer and with these models if you already own one: Niimbot D110 and D110_M, Nelko P21, and Phomemo D30. If yours is not on the list, email us the make and model and we will look at it. The FAQ covers activation and label stock.
Turn the printer on with Slabbie open. It connects on its own within a few seconds, and it stays connected while you work. You do not need to pair it again each time.
A Bluetooth label printer accepts one connection at a time, so if something else is holding it, Slabbie cannot see it. Check each of these:
A printer that is switched off and a printer another phone is holding look identical to your phone. If a connection times out, checking both is worth a moment.
Blank labels almost always mean the roll is loaded the wrong way round. Thermal paper only prints on one side. Take the roll out, flip it, and reload it.
If the print lands across the gap between two labels, open the printer, pull one label forward so a gap sits just past the head, close it, and print again.
Keep the printer within a few feet of your phone while a batch runs, and leave Slabbie in the foreground. If a batch stops partway, the remaining cards stay selected so you can print them again without re-picking them.
Align the slab inside the on-screen frame and hold steady. The brightness controls either side of the shutter help when the case is reflecting a ceiling light. Tilting the slab a few degrees kills most glare.
If the label still will not read, type the certification number in by hand and tap Cert Lookup. The result is identical.
Slabbie prices from real completed sales rather than asking prices, so a card with very few recent sales will show a wider range and lower confidence. Where there is not enough clean data to be honest about a number, Slabbie says so instead of guessing.
If you believe a specific card is priced incorrectly, email us the certification number. We look at every one of these.
Send us the certification number and we will chase it with the data provider. You can still add the card and price it yourself in the meantime.
In the app, go to Settings → Account → Delete Account. Deleting removes your account and the collection data associated with it. This cannot be undone.
Use Forgot password on the sign-in screen to get a reset code by email. Codes are six digits and expire after one hour. If a reset email does not arrive, check the spam folder for a message from support@slabbieapp.com.
Changing your email address sends a confirmation to both the old and the new address. Both have to be confirmed. Receiving two emails is expected.
Slabbie is free through December 2026. Every feature is unlocked, nothing expires, and no payment details are collected during the beta.
