Pass through a London tube station at the moment and you cannot fail to see a poster campaign for the Apple iPad, reminding potential owners of the hundreds of thousands of apps available.
This plethora of apps is not just restricted to those favouring toys from the Apple stable - fans of Android-hosted devices have a multitude of choices of available.
Travel-related tools, inevitably, feature strongly.
For obvious reasons, we choose not to write about every travel app that we hear about - there would be no room for anything else, let's face it.
But every now and again we are told about a new app that could either be the must-have of the day/week/month (depending on the hyperbole of the publication) or a head-scratcher.
Step forward Visual Currency Converter, a new Android app available in the Google Play Store.
Developed by Polish company Visuu, Visual Currency Converter asks the user to take a picture of a price (say on a menu, product listing, poster, etc), select the original currency and then it converts to up to ten other currencies simultaneously.
Sounds fantastic, right?
But if you remove the apparent wow-ness of the fact that the user can take a picture of the price to get the result, is it actually adding a layer of complexity into something as simple as getting the value of a service or product into the user's home currency?
Existing (and extremely popular) free currency converter apps from the likes of XE.com do the same job without the need to take a picture, just by - old school-style - keying in the price into the device.
So it begs the question as to whether the Himalayan mountain range of travel-reated services in the respective app stores are actually solving a problem or just adding to the noise of products available which possibly prevent the potential Everests from poking through.
In fairness to Visuu, the app is free in the Google Play Store.
Anyway, here is a clip of the app in action:
