I've used Elfster (desktop and mobile version, not the app) for 11 going in 12 years, and I'm sticking by it for now, but each year brings changes to the site that make it less and less intuitive slash user friendly. The interface changes and features get moved around, shuffled, recategorized or disappeared altogether. I find it's much more time-consuming than in years past, and seriously, I just wish they'd return to the original (ca. 2011) version. I'll keep using it for now only because it's slightly less aggravating than starting from scratch on another platform.
