Android's native Clock app to get some timely changes to its look in Android O
Version 5.1 of Clock has a new color scheme inside as well. Instead of the purple with red button seen with the current version, Clock 5.1 has a black background with a cornflower blue button. And the digital clock widget shows the time for a secondary location in a thicker, heavier font. That makes the information easier to read.
While Android users will be able to choose between Square, Rounded Square, Squircle and Teardrop for the Clock icon's shape in the launcher, Cylinder is gone, replaced with Teardrop. Overall, the features remain the same, but the Clock app is nicer to set your eyes on, both inside and out.
