I'm confused by the title. Is PoGo the first app to reach x downloads in the first week of release, or is it the most downloaded app of all time, just one week after release? Slow internet won't let me view the article.
1. Pokemon Go has more downloads during its first week than any other app has had during its own first week.
2. Pokemon Go has more downloads during its first week than any other app has had in its entire existence.
The first seems much more probable. Honestly the second isn't even reasonable when you consider apps like Facebook. Facebook has more users and more possible downloads because their app also works on tablets.Update: I don't disagree with you. It seems all articles have used the same (possibly intentionally) ambiguous quote.
Something like "Apple says Pokemon Go is the most downloaded app ever, after just one week," would have been much more clear, IMO.
