These are apps that I use on a daily or weekly basis, and in most cases these are free. As with anything Mac-related, opinions will vary, but these are the iPhone apps that I think no self-respecting marketer should be without. You can download them from the App Store or via iTunes.
Scribble – Ever found yourself in a meeting looking around the room to see if there's a whiteboard you can write on, only to discover you are out of luck? Scribble is a straightforward doodling application that I use as a mini whiteboard when I need to quickly illustrate a concept. Unlike a real whiteboard, however, my diagrams or drawings can be easily emailed to myself or others within moments.
AirSharing – This very cool app turns your iPhone into a wireless file server, allowing you to drag and drop documents between your iPhone and other computers without the hassle of connecting any cables. I use it to store backups of PowerPoint presentations for talks I am giving, and because AirSharing includes a built-in document reader, I can review and rehearse my presentations right on my iPhone.
DomainScout – Want to quickly check if a domain name is available to register? Or curious to know who the current owner is? DomainScout is a fast and easy tool that allows you to quickly conduct a WHOIS search. You can even customize it to search for your favourite TLDs, so if you only care about .com, .net and .ca domains, DomainScout can be configured to check up to three TLDs of your choice by default.
iTalk – If you're like me, you get ideas for things at all hours of the day and night. But what do you do when you don't have pen and paper handy? iTalk is a wonderfully simple voice recorder that allows you to quickly capture your thoughts, or record an entire presentation, on your iPhone. A very handy little app that turns your iPhone into a digital voice recorder, without the expense of the real thing.
Urbanspoon – Need to find a nearby restaurant or café to meet up with someone for a biz meeting? Urbanspoon is a wickedly handy tool that helps you locate whatever kind of eating establishment you are looking for. For example, if you've just landed in a strange city and need to find an affordable Vegan restaurant that's open for lunch near a client's office, just consult Urbanspoon. In seconds you will have restaurant hours, phone number, and a map of how to get there.
