With an expected transition to a larger screen on the iPhone 6, MacRumors forum member pgiguere1 has taken a look at how non-optimized apps would appear on a rumored 1704 x 960 display that would move from the current "2x" pixel doubling technique to achieve Retina quality to a "3x" technique.
In Apple's earlier transition to 2x Retina displays, it was relatively simple for non-Retina assets to be scaled up using automatic pixel doubling techniques to represent a single non-Retina pixel as a 2x2 grid of Retina pixels until developers could get up to speed. But with a potential move to 3x (or 1.5 times current Retina), many have wondered if that transition would be awkward.
As pgiguere1 shows, while developers will undoubtedly want to optimize their apps with new 3x graphical assets, automatic scaling of current 2x assets will look considerably better on this new iPhone display than non-Retina assets did during the transition to 2x.
Keep in mind however that unlike with the @1x -> @2x transition we had in 2010, this time we’d only have a 50% enlargement rather than 100%.
The thing is, a 50% enlargement with interpolation doesn’t look worse than a 100% enlargement with pixel-doubling, despite the loss of details due to the interpolation. [...]
As you can see, older non-@3x-optimized apps would actually look better on an @3x iPhone than non-@2x-opitmized apps did on an @2x iPhone. Add to this the fact that the screen's pixel density would be higher this time around, and the perceived image quality difference would be even smaller.
While Apple is unlikely to announce a new resolution for the iPhone 6 at next month's Worldwide Developers Conference, the company is likely to begin providing more tools and encouraging developers to speed a push toward resolution-independent vector graphics and other changes that will facilitate a smooth transition to denser displays. But for those developers who are not ready by iPhone 6 launch day, their users are likely to still have a decent experience with unoptimized apps.

Apple is preparing a "bold" new iPhone Pro model for the iPhone's 20th anniversary in 2027, according to Bloomberg's Mark Gurman. As part of what's being described as a "major shake-up," Apple is said to be developing a design that makes more extensive use of glass – and this could point directly to the display itself.
Here's the case for Apple releasing a truly all-screen iPhone with no...

Apple's iPhone development roadmap runs several years into the future and the company is continually working with suppliers on several successive iPhone models simultaneously, which is why we often get rumored features months ahead of launch. The iPhone 17 series is no different, and we already have a good idea of what to expect from Apple's 2025 smartphone lineup.
If you skipped the iPhone...
Apple may have updated several iPads and Macs late last year and early this year, but there are still multiple new devices that we're looking forward to seeing in 2025. Most will come in September or October, but there could be a few surprises before then.
We've rounded up a list of everything that we're still waiting to see from Apple in 2025.

Apple today released iOS 18.4.1 and iPadOS 18.4.1, minor updates to the iOS 18 and iPadOS 18 operating systems that came out last September. iOS 18.4.1 and iPadOS 18.4.1 come two weeks after the launch of iOS 18.4 and iPadOS 18.4.
The new software can be downloaded on eligible iPhones and iPads over-the-air by going to Settings > General > Software Update.

Apple today updated its vintage products list to add the 2018 Mac mini and the iPhone 6s, devices that will get more limited service and repairs now that they are considered vintage.
The iPhone 6s initially launched in 2015, but Apple kept it around as a low-cost device until 2018, which is why it is only now being added to the vintage list. The iPhone 6s had Apple's A9 chip, and it was...

Any perception of how "rough" or "smooth" this will be is irrelevant.
The complaint originates from developers who spend more time complaining than developing.
Remember how "rough" it was getting native iPad apps in 2010? Remember how "rough" it was waiting for retina iPhone apps later in 2010? Or how "rough" it was for iPad retina apps in 2012? Or how "rough" it was for developers to move to the iOS 7 design language? Or my personal favorite, how "rough" the Intel transition was? And the "rough" transition to OS X retina apps for the rMBP? And why stop there? Remember how "rough" System 7 to Mac OS 8 was? And OS 9 to OS X?
The point is, they'll always call it "rough", and it's never as bad as they say it is.
My One M7's 1920x1080 res is obviously much sharper than the 1136x640 of my 5s. People keep telling themselves higher res is pointless, and most of them have never tried.

That's a nice list. Where is your evidence that it's not rough? It was and is. It often multiplies the time and effort that is needed to complete a project. A limited number of screen resolutions is an advantage that iOS developers have enjoyed for a long time. Customers on the platform value a pristine look and polish and the competition is very heavy. When someone tells you your job is about to get twice as hard and you aren't getting any more time or money to work on it, it's not such an unusual thing to complain.
