MT助手 is an iPhone application developed by keke Cai under the utilities and tools category. This free app is an effective solution for securing limited-stock items such as Feitian Maotai. The app provides a floating window with millisecond-level precision, which can float on top of any app and help users accurately snatch up various limited-stock items.

One of the main features of MT助手 is its floating window that can be displayed on top of any page to enable precise time management for limited-stock item purchases. Additionally, this app provides a unique feature that highlights the clock digits in red as soon as the set time for a specific purchase is reached, allowing users to grasp the exact time without any error or delay. The app also provides a "pre-color-change" feature that enables users to set a time to enter the purchase page in advance, making it easier to purchase limited-stock items such as Feitian Maotai.
