From publisher blurb:
The Creature Companion is a collection of simplified stat cards with artwork for all 88 beasts (including dinosaurs) from the 5E Monster Manual. it is a way to make Shapeshifting, Polymorphing and Conjuring Animals a lot more fun for players and putting beasts into any encounter a lot more dynamic for a DM.
The layout was designed with print in mind, with the aspect ratio of poker size cards, but can also be easily used on a smartphone/tablet. The digital product doesn't just contain a booklet with all the creature cards (back and front) but also a Zip file that includes all the digital stat cards (for ease of use on a tablet or phone). You can also find a legend of the icons that were used in the layout to highlight specific stats and actions in the preview of the product.
