ArkRecord is a free and open-source Chrome add-on that allows users to track and analyze gacha data from the popular mobile game Arknights. By continuously monitoring and recording the gacha data displayed on the Arknights website after logging in, ArkRecord provides users with a way to keep a comprehensive record of their pulls and perform basic statistical analysis. This is particularly useful as the Arknights website only displays gacha data for a maximum of 30 days or 100 pulls.

With ArkRecord, users can track and analyze various aspects of their gacha pulls, such as the rates of obtaining 5-star and 6-star characters, as well as the rate of duplicate pulls. The add-on also supports data export and import, allowing users to easily backup and transfer their gacha data.

Additionally, ArkRecord offers features like chart analysis, statistical analysis, analysis of pity values, and the ability to hover over tables to view the corresponding operator names. Users can also view a timeline of gacha pool releases and track their recharge and originium stone consumption data.

Please note that ArkRecord is developed by fiammetta and is available for the Chrome platform. It falls under the category of Browsers and the subcategory of Add-ons & Tools. The add-on is free to use and is licensed under an open-source license.
