Gadgets: Making travel easier

Currency Simple Converter App
There are plenty of currency conversion apps out there, most entirely functional and practical, but usually aesthetically-challenged. Currency Simple Converter delivers a smoothly intuitive interface and doesn't stint on the financials. 160 currencies in the database, easy to set favourites and a graphic 6-month rate tracker all work a treat, along with a big keypad. But it's touches like the cool number animation and swiping interaction that lift it above the common currency.

Blink/Steady Bike Light
With each one machined from a chunk of aluminium, Blink/Steady is already easy on the eye before we even get to the smarts inside. Because its compact body is all brains, and just a couple of AAA batteries. No on-off switch, for instance, because an accelerometer triggers it when you're moving or not. And its LEDs come on automatically in low light thanks to a photosensor. Two light modes, the eponymous blink or steady, are set by which ever side is turned up or down. And the whole waterproof unit is bolted onto the seat post.

USB Utility Charge Tool
Although its Swiss second cousins once-removed are unlikely to be too welcoming of the comparison, the USB Utility Charge Tool's design muse is as obvious as its name is clunky. Still it's a neat conceit: 4 connectors (standard, micro and mini USB and an Apple 30-pin Apple) flip out from the penknife-ish body. It comes a range of colours, but no Lightning connector yet for newer Cupertino fare.
