Each weekend, Mashable selects startups we think are building interesting, unique or niche products.
In celebration of the release of the iPhone 4S, were featuring three startups with iPhone applications that will help you maximize your mobile lifestyle.
CardFlicks answer to the digital business card is one of the best weve seen. Crowdmug could help you figure out where to go for a exciting night out. And Floop proffers both an entertaining and informative mobile polling experience.
CardFlick: iPhone Business Cards
Quick Pitch: CardFlick lets you create and share digital business cards with your iPhone.
Genius Idea: Digital business cards with panache.
Mashables Take: We know youve got (too many) options, but if youre still searching for just the right digital business card application, consider giving CardFlick a whirl.
The application offers by far the simplest and most elegant card creation experience on the market, and it provides you with top-notch card design themes. Best of all, if youre in the same room with another CardFlick user, you can literarily flick to send your card to your new contact. Our only gripe is that wed love to be able to create more than one card.
And despite competition from a boatload of similarly-purposed applications, CardFlick reports it saw nearly 50,000 downloads in a 30-day period.
Crowdmug: See Whats Happening
Quick Pitch: Crowdmug lets you request photos or videos of places to see what the scene is like before you go.
Genius Idea: Cash-incentivized visual status updates.
Mashables Take: Finding the right bar scene can be a pain, so much so that startup Crowdmug is testing the theory that youll offer up a few bucks to get a first-hand glimpse at whats happening at a particular venue.
The Crowdmug iPhone application lets you make location-related requests. You tell Crowdmug what you want to see (either a photo or video), where you want to see it and how much youre willing to pay for your request. Your request is then sent off to app users in the area.
The app could, theoretically, come in handy if youre curious about iPhone 4S lines, the crowd at the pub across town or the status of tables at your favorite local coffee spot.
You can also use Crowdmug to follow city-specific feeds of photos and videos being shared by other users who are out and about.
Floop: iPhone Polling

Quick Pitch: Floop is an iPhone app for polling and visual opinion graphing.
Genius Idea: Poll graphs that update in real time.
Mashables Take: This nifty iPhone application lets you measure the pulse of your friends or the community at large on a topic of your choosing. You can watch the opinion line graphs fluctuate in real time as responses pour in, cast your vote in others polls, and participate in group text or picture threads related to polls.
Plus, playing with Floops voting tool can be rather fun just slide the yellow dot up or down to express your response to a question. Then, rotate your phone to landscape mode to see how others have voted over time.
