iWatch is a simple and accurate digital watch with a largest display. You can freely change the theme color and the font. In digital clock apps, we often see apps that cause so-called "time skipping", in which the number of seconds that should be updated every second is rarely updated, or skips one second and advances to the next number of seconds. You can rest assured that the iWatch is expertly programmed to prevent such erroneous second display. The design is particularly simple and easy to read the time. Long tap “AM”, “PM” or “24h” on the screen to switch between 12-hour and 24-hour time. Long tap ⓘ (information button) to customize the theme color and the font. Supported Multi-Window on iPad. The developer assumes no responsibility for any loss or claims by third parties which may arise from the use of this app. Terms of Use: This application is provided under the Apple Standard End User License Agreement (EULA). https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
