Frequently asked questions

How do reviews work?

After a completed purchase, buyers and sellers can review each other within 14 days. Reviews become visible once both have submitted, or when the review period ends. About reviews

How do I find a book?

Enter a title, author or ISBN. On iPhone, you can scan the barcode or read the title with the camera. If the wrong cover appears, compare the ISBN and select the correct edition; different editions of a book may have different covers.

How do I publish a book?

Add the book to your iPhone Shelf, enter its condition and price, and optionally add up to eight of your own photos. A draft stays on your iPhone. Only “Publish on Relibro” sends it to the marketplace; you need a seller account for this.

How do I remove a listing?

Open “My Shelf”, tap the three dots next to the book and choose “Remove listing”. If the book has been published, it is also removed from the marketplace. If an error message appears, send us the listing number or link.

Report a problematic listing

If a book listing is incorrect, misleading or unlawful, send the listing link or number, the specific content you object to and your reason to info@apptheism.de. We review that specific listing and reply to the sender’s address. If you disagree with a decision about your own listing, you can also request another review there.
