AppAdvice has teamed up with Emendo Media in order to offer you a chance to win one of 10 promo codes for Templates for Numbers Pro ($4.99) for iPhone, iPod touch, and iPad.

Templates for Numbers Pro is a productivity app that allows you to expand the possibilities of Apple’s Numbers app for iPhone and iPad by providing you with 115 professionally designed spreadsheet templates.

The templates are divided up into three main categories: finance, time, and personal. Each main category has sub-categories that allow you to refine your search even further and quickly discover exactly what you’re looking for. Tapping on a listing will bring up a preview of the template, which can be zoomed in on using the usual pinch to zoom gestures. Arrows at the bottom of the screen allow you to quickly scroll through all of the templates in a sub-category.

Templates, templates, and more templates.

Exporting a template from Templates for Numbers Pro to Numbers is as easy as tapping the share button in the upper right corner of the screen and selecting the “Open in Numbers” option. You’ll then automatically be brought into Numbers as the template is importing, and it should appear within seconds on the Documents screen. From here you can edit and customize the template however you wish.

Here’s just a sampling of the types of spreadsheet templates included in Templates for Numbers Pro in order to give you an idea of what to expect: accounting, budgets and proposals, invoices, calendars, time tracking, health and fitness, home and family, and lists. Of course, you need to have Numbers installed on your iDevice in order to utilize Templates for Numbers Pro.
