Here are the tools I've used since the beginning to have a web presence in order to complement the information on the App Store:
- Domain Name hosting: www.godaddy.com
- Web hosting: Google's Blogger: www.blogger.com (for www.buildingiphoneapps.com)
- Web hosting: Posterous: www.posterous.com (for http://buildingiphoneapps.posterous.com)
- Web editing tool: Apple's iWeb for www.tinysofty.com and My Developer Notes web site
- Web hosting: FatCow for hosting www.ultpassmgr.com
- Screenshots of my application in action for iTunes Connect are taken from my iPhone 3GS or the Xcode simulator and for that I'm using LittleSnapper from RealMacSoftware.
- Screencasts showing my application in action are done with ScreenFlow (which is very cool software BTW)
- Email address of TinySofty is using gmail.com
- iPhone 4S as my development and testing device.
- Using www.testflightapp.com to get beta testers on my iOS app testing.
- File hosting for some of blog posts containing files to download: some on MobileMe's iDisk or www.dropbox.com
- Apple's Keynote for user interface prototyping and many user interface elements
- Pixelmator from www.pixelmator.com for a few graphic elements
- Remember The Milk for my hosted to-do list manager (also includes iPhone app)
- Google Analytics for my blog statistics (very useful)
- Google Feedsburner to manage the blog's RSS feed and stats
- www.appfigures.com for my application sales figures management
- www.mailchimp.com for mail announcements
- www.observerapp.com for a better looking view of my web sites analytics
- iMockups HD for iPad, a prototyping tool. I'm not using this one anymore.
- Blueprint for iPad from www.groosoft.com, is very a very good prototyping tool for iOS apps. But now my favourite is App Cooker from www.hotappfactory.com (see my review).
- Sketch: better tool than DrawIt.
