Hiri
Hiri
An incredibly easy way to manage your inbox. Built for the Microsoft email ecosystem. We also support: outlook.com, hotmail.com, live.com and msn.com. Email doesn’t have to be ugly. A cluttered inbox is like a cluttered desk - it makes it difficult to get in the right headspace. We’ve used the UX principle of progressive disclosure throughout Hiri so you only see what you need when you need it. Good design is at the heart of what we do. For example, regardless of what resolution or what size monitor you use the center pane in Hiri will always remain the same width. This is because the optimum readable length of a sentence is about 96 characters. Any longer and it can be difficult to find the beginning of the next sentence. Any shorter and your eyes need to work harder, causing fatigue.Starting Price: $39 per year -
