About this app

■ A difference of 0.01 seconds can make a difference. Whether it's securing tickets to a popular concert, registering for university courses, or purchasing limited edition merchandise... Have you ever narrowly missed a chance? Now, check the site's "real server time" instead of your smartphone's time. "Chalna" will dramatically increase your chances of success.

■ Why "Chalna"? (Key Features)
1. Ultra-precise synchronization down to the millisecond (ms) level. It goes beyond simply retrieving server time. It calculates network latency (RTT) and the average deviation that occurs during data transmission in real time to correct for errors. With Korea's highest level of precision, it pinpoints the true 0.01 seconds.
2. One-touch server preset support: Interpark, Yes24, Melon Ticket, and even major university course registration sites! Register and track your desired server with a single search, without having to manually enter addresses.
3. Intuitive countdown & target setting: Set a target time and see the remaining time in real time, down to the millisecond. Prepare for the tense moments before the game opens with a visual countdown.
4. Clicking practice for a realistic feel. Game theory and real-life are two different things! Test your click reaction speed with the in-app "Time Matching Practice" feature and get used to clicking at the 0.00 second mark.
5. "Reminder Reservation & Schedule Registration" to help you never forget (HOT!). Register important ticketing or class registration schedules in advance. Customized reminders will be sent before your target time, ensuring you'll be prepared even during your busy schedule.
6. Direct access to the website for instant access. Checking the time and accessing the site are separate things? "Challna" provides an outlink feature that instantly connects you to the relevant website, reducing your connection time.

■ Highly recommended for: • Performance enthusiasts who always suffer defeat in picketing (the bloody, often tedious, ticketing)
• College students desperate to successfully register for popular majors
• Anyone who needs to connect on time, such as when booking holiday train tickets
• Perfectionists who don't tolerate even a 0.01-second error
■ Note
• This app may experience slight errors depending on network conditions, so we recommend using it in a stable Wi-Fi or 5G/LTE environment.
• Be sure to use the click practice feature beforehand to ensure successful results!
