Update: Pixelmator for iPhone is now available. Download it here.
Pixelmator is releasing an update to its iOS app tomorrow, making the app available on the iPhone for the first time ($4.99). The universal app means you can buy once and download Pixelmator on both iPad and iPhone. Existing iOS users of the app naturally get the iPhone version for free as an update. The new version also brings the Distort tools, like warp brushes, to the iOS app for the first time.
Pixelmator for iPhone works very similarly to the iPad version but scaled down for the smaller canvas. You can read our full review of the iPad app from last year. Rather than popover panels, selecting an action opens full-width menus encapsulating options. This is a necessary concession for the size of the display.
