Welcome to our App of the Week series where we highlight Smartphone applications for business.

This week we are going to take a break from complex GPS apps to feature a simple, but highly useful app.  In fact, it's considered by many to be an ideal "first purchase" for new business iPhone users. This week's app of the week is AppBox Pro (iTunes link).

The best way to describe AppBox Pro is a cross between a Swiss Army knife and a Loonie Store.  It's one app with dozens of features and costs only $0.99.  Here is a list of some of the functions included in the app (again, all of this is $0.99).

Battery Life - detailed view of your iPhone's battery level including remaining talk, standby times and Internet usage.

Currency Converter - convert from CAD to 194 world currencies.

Dashboard - quick view of your battery, memory and upcomming holidays.

Date Calculator - calculate days from a date (for example, what is 83 days from next Thursday?).

Days Until - countdown of days until an event.

Flashlight - turns your screen bright white (or other colors) - ideal if you're trying to open a door lock on a dark night.

Holidays - displays holidays for 95 different countries.

Level - uses the built-in iPhone sensors to display a bubble level. Not a replacement for a carpenters level, but great to hang a picture in the office.

Loan Calculator - accurately calculates payments based on specified term and interest rate.

Random Number Generator - pick a number between 1 and 1000?

Sale Price Calculator - easily calculate a sale price discount, including taxes.

Tip Calculator- so very handy when out for a business lunch.

Translator - basic translation for 61 languages.

Unit  Converter - 17 categories and 357 units covering things like meters to feet and Celsius to Farenheiht.

There's even more, but the point is clear: you get a lot of usable features for your (almost) dollar.

From a business perspective, this app makes sense - especially for a new iPhone user. Each mini-app that is included in AppBox Pro is perfectly  functional and for $0.99 it's a low cost way to try out a large selection of features.  Features like the savings calculator can help save time and others like Battery Life can help new users learn to manage their iPhone better.

And did I mention it's only $0.99?
