Big Clock
he Coding Monkeys’ Big Clock HD app is a must for visually impaired travelers. Just double tap to rotate iPad orientation to landscape view and set it atop a hotel room TV or table. You’ll be able to read it with a glance while lying in bed. The clock displays time and date in the region format and language the device is set to. The app prevents devices from auto-locking when displaying the time.
