Golfshot Golf GPS
This one is for all those budding Tiger Woods' out there who aren't lucky (or talented) enough to earn their own caddy. Thankfully, the Golfshot is the next best thing, providing you with accurate stats so you can knock some strokes off your game. It has 22,000 courses ready to view, allows you to guage distances, helps with club selection and can even keep score. Best of all you can hurl abuse at it and it will still do your bidding... Like a real caddy, except marginally cheaper. It may just give you the edge over your rivals, but don't expect an invitation to the PGA overnight.

The pathologist's new best friend - Interpath allows those disease detectors to view high-res images in the palm of their hand so that they can diagnose patients remotely.

Lexi-COMPLETE is your one stop shop for diagnosis info, disease management, medicines and all the other things that a competent doctor should probably already know.

Luminair
You know when you're at a show and the lights magically change to enhance the action on stage? Well it's not magic (no really), that's the hard work of theatre technicians. This ingenious little app allows said technicians to control lighting fixtures through their iPhone, and basically gives them a license to show-off. Needless to say, if they get too cocky or drop the phone there could be a few surprises in store for the performers and audience.

Nursing Constellation Plus
Another medical related app, this time for nurses. It includes features such as a medical dictionary and, erm... calculator. The "drug dosing calculation tool" doesn't exactly inspire confidence in our medical staff, does it?

The ROSIE home automation system allows users to control their a/v systems, lighting, security, and other services all from one app. When you're feeling particularly lazy, this'll gift you control pretty much everything from the comfort of your couch.

SAP Business One
This particular financial worry syncs with SAP's BusinessOne financial management software - which is designed for sales reps or marketing/finance execs.

TomTom app
A fully fledged navigation app from one of the leading sat-nav manufacturer was never going to be cheap now was it? The layout will be welcome to TomTom lovers, but we still feel that £60 is a bit harsh. This is just the tip of the iceberg however...
Price: £59.99 @ the iTunes store

Wolfram Alpha
The Wolfram is the Jekyll and Hyde of apps. The good side is that it's a search engine promising more intelligent search results than the current breed. In fact, from the promo, you'd think you were buying some sort of advanced military tech; "Drawing on 20+ years of development, 50,000+ built-in algorithms, and 10+ trillion pieces of continually updated and curated data, the Wolfram Alpha app is the ultimate replacement for any kind of calculator or reference book-and much more." The downside is the £30 price tag; a bit pricey, especially when the ever useful Bing/Wikipedia combo is gratis.
