I'm looking for an app to help make my work easier and more efficient?

I work as a retail manager and I have to merchandise my stands daily and look at sales. I want an app that makes my life a bit more efficient. I want something that lets me plan what is on my stands and keep track of how much money it is taking something simple and easy to use. Any ideas? I have a iPhone btw so anything in the apple store preferably

EBay

Forget so called technology (the bane of life enjoyment and efficiency) and go simple and effective… Such as learning and using a tickler (43 folder) filling system. Then, when you have made it big, if you ever come down with Alzheimer's, that's the time to wile away your workday, playing with app's and getting paid just the same.

  • What's easier FB safari or FB app? I can't decide if I should the FB on either of my devices I got an iPod Touch and a Samsung phone if you don't have the app on either you can't do timeline photos. On iPod FB safari it will go to mobile uploads or IOS I don't want that plus the safari on either makes the photo albums look weird. Which one is easier?
  • What apps can make living in New York easier? My sister is moving to New York in a few weeks. She has never been and is somewhat intimidated by the whole change. What can make the transition easier? Ipad or iphone apps are the things I'm actually looking for. Maps, restaurants, discounts, anything goes. Anything you think that will make life easier there?
  • More you use an app the more space it takes up on iPhones and iPads? I have an iPad and new iPhone 5 that I just got. I have rhapsody on both the same app and amount of music basically (iPad as seven more songs on app) but on the iPad the rhapsody app takes up 2.8 GB and the iPhone takes up 1.8GB. Why is that? The more use the app the more space it takes up even if you're not adding new content?
  • Looking for a calendar app for both iPhone and laptop, besides standard iCal app? IIm trying to find a nice calendar app that can be used between both my laptop (Mac) and iPhone. I need it to be able to be color-coordinated and also to have daily, weekly, and monthly views. Preferably free, but willing to pay a little bit for it. Found one I really enjoy, but between the desktop version and the phone version, it's more than $30 and IIm not sure I want to pay that much.
