Appmakr is a free web service that lets you make your own iPhone apps for your blog or Website and cutomizing it without any coding. All you need is a RSS feed url of your blog and a iOS Apple Developer account. App makr is completely free and charges no extra fee for creating an iPhone App. iOS developer account will cost 99$ per year but in my opinion it is worth getting an account. App Makr also lets you make Android and Windows Phone apps but they are currently in BETA.
Update: Please try AppGyver too. It works almost the same way.
App Makr allows you to add Your Blog, Photo albums, Messaging, HTML/ Phone Gap tabs, and much more into your app….
The first tab namely ‘Art’ allows you to configure the Icon, Splash Screen, Name of the app, etc. The next tab namely ‘Tabs’ allows you to add all sorts of features into your app. The ‘Customize’ tab is used to change the look and feel of your app. The ‘App info’ tab is used to give information about app. Mind you, If apple finds any irrelevant information in the description of your app, they may reject your app. The ‘Monetize’ tab is used to monetize your app. The ‘Publish’ tab is used to publish your app into the App Store. You will have to login to your Apple Developer account and publish your app directly from oyr App makr account.
Here’s a good video demonstration of App Makr.
