Obama Or McCain Polls is an iPhone app that will be useful for exactly one day: Today. Once the election is over, assuming we don't have a recount situation like in 2000, no one is going to use this application ever again.
Sure, it has some nice features such as overall poll results, Obama polling breakdown, McCain polling breakdown, poll results by state, poll results by ethnicity and so on, but there's a big barrier to entry aside from the fact that will only be useful today: It's not free.
Surely that's a part of Relativity Solutions (the company behind the app) plan. After all, why create an app that will last for a day if you get absolutely nothing out of it? But even if the $0.99 app sells like crazy today, will it really have been worth it in the long run for the developers? I guess we'll know if they release another one in 2012.
If you really feel the need to pay a buck to have a one day application, find Obama Or McCain Polls here.
