I use my phone on a rather profound constant throughout the day. I start the day checking my Hive account and write, reply, respond to mentions. I also do some Hive work in the evenings.
During the day it is Chrome/Google, Google maps, weather apps and so much more that I use my time on. Not to mention Whatsapp...
But phones have become massive productivity tools that we just cannot ditch! They are mini computers.
That said. Social media and games and advertising have a way to drain our time from the important stuff.
