Mellow is an Android app developed by tetsuoyamashita that offers a custom-tailored selection of inspiring fine art and images. It aims to bring pleasure, tranquility, and inspiration to its users through a range of artworks, including paintings, drawings, sculptures, ceramics, photographs, graphic arts, and much more. The app showcases works by exceptional artists such as Vincent van Gogh, Claude Monet, Pierre-Auguste Renoir, as well as contemporary and emerging artists.

Mellow is designed to deliver up to 10 daily art images that refresh and delight based on your preferences. It also allows you to discover more artworks outside your daily Mellows and search for artworks according to the artist. The app also lets you follow your favorite artists, share the artwork you like, and invite your friends to join in an art escape with you. Additionally, you can support your favorite artists on the platform by donating vibes conveniently using in-app purchase. If you are an artist, you can apply within the app to be a Mellow artist and manage your profile all within one platform.
