How is this product different from the competitors? Is there any possibility to delete spam?
I like the app as it helps me to focus on the real work to happen. Simple and straight forward. Get me my mails in doses. It's a good help on a way to more discipline.
If you value your time and work you need big, focused time intervals to focus and creative thinking. Connection to the network should be restricted to 1 hour 1-3 times per day max for email, phone calls, and whatever social crap you are stuck into.
