Acuwin.com is not an application, but a web-based service that “guarantees”:
– thousands of contest entries per month
– user-selected contests
– a contest-specific email address
These are all the things the casual contest enthusiast needs!
While their site does not provide any testimonials nor explicity state that their members have won prizes, the site implies that their members won 96 cars last month and a total of 873 last year, among other prizes. (I suspect that these numbers don’t ever change on the site–we’ll let you know.)
From our perspective, this is not the kind of thing we want interfacing with our clients’ contest entry pages and, since I’m skeptical about it, we’ll be testing their service and publish our findings.
