The differences between iPad and iPhone apps

Thanks for sharing. I enjoy it.

I still can't understand why we need to separate these apps(iPhone and iPad).moreover its good to have a single apps for different gadgets................

While I see many people won't pay for the "same" app twice, I'm not sure how much that will affect whether or not they charge for an iPad version. I think it depends on how much work is involved in redesigning the app to take full advantage of a different device. In my opinion, depending on the app, I will pay a second time for a version that is substantially improved the new form factor. I think that is fair. However, if it is simply the same core app only bigger, I'll just use the existing older app.

I think the smart developers will completely redesign some of their apps to make the most of what is likely to be an almost completely different experience. In my mind, that is worth paying more for in some cases. Again, it depends on the app, what purpose it serves for me, and what improvements were made. It takes time and resources to make some of these changes and it is thus reasonable to expect compensation if people want those improvements.

Some good points here.

Apple made trade-offs in allowing iPads to run iPhone software. They give iPad a running start with a smashingly successful platform, but the actual apps are just "good enough" for that device and not tailor-made.

Apple definitely has to think about how best to accommodate the apps that offer smaller functionality. I agree that a widget mode or Dashboard is an interesting potential solution, but that will entail allowing third-party app multi-tasking, something that Apple has been resistant to doing on mobile devices with batteries and (relatively) low powered chips.

I wish I had the answer!

The differences is indeed noticeable. I have documenting on my blog the changes we have been making on our game as we redo it for the iPad. To read in detail the changes we have had to made, especially to the interface go to http://www.smartboxdesign.com/blog/.

The real difference between iPad and iPhone IM clients will probably be that IM clients on the iPad will adapt a safari browser pane to go along with the IM client so that people using the app can "multitask".

You'd be crazy not to take advantage of the iPad space. For instance, my basketball scoring app BBKeeper on the iPhone has to navigate between screens to view the boxscore - on the iPad I have space to have it displayed full time, AND increase the size of the UI elements for easier use.

The human-interface guidelines and SDK docs have said this from the get-go. There will be 3 classes of apps. The first is iPhone apps that work out of the gate in tiny or 2x mode. The second is custom-built iPad-only apps. The third, preferred, form of app will be a universal app that tests for what hardware it's running on and adapts to either the iPhone or iPad HIGs that are clearly layed out.

I thought it was obvious that there would be a separation between iPhone apps and iPad apps. The initial selling point is that right from the start there will be thousands of apps that will run on the iPad, but clearly the larger form factor makes different, better interfaces possible.

I would not expect, if I have a license for an iPhone app, to get the iPad optimized version for free. That may vary from publisher to publisher, but given the redevelopment required to create a new interface and add new features, I don't think it's unreasonable to have to pay an upgrade fee, or buy the new app outright.

For an example of how bad an iphone app may end up looking on the iPad, look at the tower defence game Fieldrunners on a Playstation 3 - the graphics are pretty ugly on the big screen because the publisher didn’t bother to redo the graphics for the high definition PS3, simply enlarged them so that the game ends up looking rough around the edges so to speak.
