AnkiMobile is a mobile companion to Anki®, a powerful, intelligent flashcard program that is free, multi-platform, and open-source. Sales of this app support the development of both the computer and mobile version, which is why the app is priced as a computer application. AnkiMobile was written by the lead developer of Anki and AnkiWeb, and it has been around since 2010. Beware other apps using "Anki" in their name that have sprung up recently - they are not compatible with the rest of the Anki ecosystem, and they offer far fewer features, despite charging expensive subscriptions. Some of AnkiMobile's features include: - A free cloud synchronization service that lets you keep your card content synchronized across multiple mobile and computer devices. This makes it easy to add content on a computer and then study it on your mobile, easily keep your study progress current between an iPhone and iPad, and so on. - The same SM2 and FSRS scheduling algorithms that the computer version of Anki uses, which remind you of material as you're about to forget it. - A flexible interface designed for smooth and efficient study. You can set up AnkiMobile to perform different actions when you tap or swipe on various parts of the screen, and control which actions appear on the tool buttons. - Comprehensive graphs and statistics about your studies. - Support for large card decks - even 100,000+ cards. - If your cards use images or audio clips, the media is stored on your device, so you can study without an internet connection. - A powerful search facility that allows you to find cards that match criteria such as 'tagged high priority, answered in the last ten days and not containing the following words', and automatically place them into a deck to study. - Support for displaying mathematical equations with MathJax, and rendering LaTeX created with the computer version. - Support for adding images drawn with the Apple Pencil to your cards. Please note that AnkiMobile is currently intended as a companion to the computer version of Anki, rather than a complete replacement for it. While AnkiMobile is able to display and schedule your cards in the same way the computer version does, certain changes like modifying note types need to be done with the computer software. Add-ons are not supported, so while you can study image occlusion cards created with the computer version, they can not be created within AnkiMobile. For this reason, please start with the computer version of Anki before you think about buying this app. The cloud synchronization service is optional, and data can also be imported/exported from the app via a USB cable or AirDrop. Like all apps, AnkiMobile can be purchased once and then used on multiple devices in a household using the same Apple ID. Family sharing is also supported (apart from in India). For information on bulk discounts for educational institutions, please see Apple's Volume Purchase Program. For more information on AnkiMobile, including a link to the online manual, please have a look at the support page: https://docs.ankimobile.net/support.html. If you have any questions or want to report an issue, please let us know on our support site and we'll get back to you as soon as possible.
