It used to be a great app which let you test your connection, find nearby cell towers (of any provider), and compare coverage and performance. It was really helpful for finding where you needed to be to get better coverage (something increasingly valuable when you're in rural areas with spotty coverage). Lately they've commercialized and most of those features seem hidden. You can still contribute and test your performance, but what good is that if you don't get the benefits of being crowd-sourced? (there's plenty of alternatives for "speed" tests out there). Time to look elsewhere. Would be nice if it were non-profit, maybe even open-sourced.
