iPhone Simulator - the 3 best websites

An iPhone simulator is particularly useful for web designers or programmers who develop mobile websites and want to test their layout in various screen formats without great effort. We present 3 sites that make the iPhone look'n'feel possible in the normal desktop browser.

Simulates smartphones, tablets and even TV: Screenfly

On screenfly you can not only reduce your website to iPhone format; the tool also simulates other common mobile devices - from the Samsung Galaxy III to the Nexus 7 to the large and small iPad.

• With the "Rotate" button you can switch from portrait to landscape.
• Various TV resolutions can also be simulated.
• Alternatively, you can freely configure the desired display size.
• When testing the iPhone portrait format, however, a horizontal scroll bar appears in the viewport, which does not appear on the "real" iPhone.

ipadpeek: The Apple specialist

ipadpeek is - as the name suggests - specialized in iOS devices.

• The iPad and iPhone (4) view are supported; there is also an extra option for the iPhone 5.
• The iPhone simulation looks "cleaner" than with screenfly - no horizontal scroll bars appeared, even mobile forms of advertising are displayed correctly.

Responsinator: Everything at a glance

While the respective devices have to be selected individually for the iPhone simulators mentioned above, the Responsinator provides you with all possible screen formats at once. This allows you to check relatively quickly whether your website is displayed correctly on the most common tablets or smartphones.

• In addition to iOS and Android screen sizes, there is also a website preview in Kindle format.
