A tricky problem I had to be thoughtful about.

As phones get larger, reaching the top parts of the screen gets much harder. My one regret with my current phone is that it's too large, I wish I'd prioritised having a smaller screen more, but for the price, camera and battery performance, this was the best I was able to do. Marcin Wichary writes that the iOS browser Quiche Browser handles this by letting users adjust how far up the screen they want UI elements to sit in "Comfort Mode".

When laying out the icons on my home screen, I do something similar. The weather and time widgets go at the top since I rarely have to interact with them, and the most frequently used apps go at the bottom right so I can easily reach them with my thumb.
