Reviewer's note: this review is for version 1.0 of the app. A new version (1.1) has just been released, promising great GPS accuracy; we're currently trying to acquire a copy of this latest version for review.
At first blush, TomTom on the iPhone looks remarkably like TomTom on, well, TomTom. The somewhat blocky map, with its range of pastel colours, looks almost unchanged, while the status boxes underneath have been given the merest lick of paint, along with some smoothed out fonts for good measure. It flits between portrait and landscape modes quickly and attractively.
Tap the map to bring up the main menu, though, and it's apparent that you're now on Planet iPhone. The Dutch company has dumped its usual icon-based interface for Apple's suite of swipe to scroll menus and lists. To make it easier to use when Apple's fruity phone is stuck to the windscreen, menu items are double the normal height and feature big friendly icons.
