Web clients are available as companions to the desktop version: AnkiMobile for iPhone, iPod touch or iPad (paid) AnkiWeb (online server, free to use; includes add-on and deck hosting) AnkiDroid for Android (free of charge, under GPLv3; by Nicolas Raoul) The flashcards and learning progress can be synchronized both ways with Anki using AnkiWeb. With AnkiDroid it is possible to have the flashcards read in several languages using text-to-speech (TTS). If a language does not exist in the Android TTS engine (e.g. Russian in the Android version Ice Cream Sandwich), a different TTS engine such as SVOX TTS Classic can be used. History The oldest mention of Anki that the developer Damien Elmes could find in 2011 was dated 5 October 2006, which was thus declared Anki's birthdate. Version 2.0 was released on 6 October 2012. Version 2.1 was released on 6 August 2018. Utility While Anki may primarily be used for language learning or a classroom setting, many have reported other uses for Anki: scientist Michael Nielsen uses it to remember complex topics in a fast-moving field, while others are using it to remember memorable quotes, the faces of business partners or medical residents, or to remember business interviewing strategies. In 2010, Roger Craig obtained the then-all-time record for single-day winnings on the quiz show Jeopardy! after using Anki to memorize a vast number of facts. Medical education Anki is an important resource for many medical students in the US. A study in 2015 at Washington University School of Medicine found that 31% of students who responded to a medical education survey reported using Anki as a study resource. The same study found a positive relationship between the number of unique Anki cards studied and USMLE Step 1 scores in a multi-variate analysis. Some third-party resources, such as Boards and Beyond, have Anki decks based on them. One Anki deck developed by students at the University of Utah School of Medicine, AnKing, aggregates information from multiple third-party resources and has become the primary method of USMLE Step1 and Step2 study for many students, having been downloaded over 200,000 times as of 2021. Copera Inc.'s Anki for Palm OS An unrelated flashcard program called Anki for Palm OS was created by Copera, Inc. (formerly known as Cooperative Computers, Inc.) and released at the PalmSource conference in February 2002. Anki for Palm OS was sold from 2002 to 2006 as a
