I first purchased iA Writer in 2010 (I think?) when I was working on my Masters Thesis and wanted an app with a clean focus mode to help me write and keep me engaged in the work that needed to be done. Since then, there has been continuous updates and a clear dedication to keeping the app relevant. I continue to use it as my go-to writing app for research, course prep (I’m a Professor), and random info I like to keep track of.
