Robust. Artful. Concerned. Considered. Measured. The newest update took more time from the dev so it couldnt ship right for ios 8. But instead of looking elsewhere I saved my pennies by not trying other apps and waited. Completely worth it. Pushpin remains a work of love and one of complete and total utility. It makes me love Pinboard and makes a great tool for my life. I also love Spillo for Mac, and find that these solutions are the best way to manage bookmarks and by extension - research. What a great app, boy oh boy.
