Physical Description
iPhone OS 1-tan, or also known as iOS 1-tan or Alpine is shorter (3’0”) then Julia (iPhone 2G-tan) and has long, loose blonde hair, an oversized light green sweater with white irregular shapes on it, a large cream and brown coloured skirt that covers her feet, black shoes and a pair of tiger ears and tail. She also has a compass around her tail which is the Safari icon. Sometimes Alpine has an envelope in her mouth for no reason.

System 6-tan
Alpine and System 6-tan (Antares McIntosh) first met when Antares was told to look after Alpine one day. Antares did not agree to look after her as she was afraid it would ruin her tough image but eventually, once Antares noticed Alpine was being treated terribly by Julia she was willing to look after her.
