The Word Online web app comes with a few default resumes, however these are likely the most commonly used resumes out there. To make your resume look unique, you can use these additional resumes to give your resume a different look from the normal - and hopefully stand out from the rest of the resumes.
Even if you don't have Microsoft Word (the downloaded program), you can still use Word Online and these extra templates for free as long as you have a Microsoft account. These programs aren't as feature-filled as the paid versions however.
Resume Companion is buddied up with numerous other websites to polish their pocket. Checked by default are 2 ways that sites can spam your email. Even their own business model is sketchy - if you forget to cancel or upgrade your $2 14 day trial, you will be automatically enrolled in their $39.95/month plan while the alternative $7.95/month plan is the exact same - they are hoping you forget to cancel so they can gouge your wallet.
To use this service, you will need to pay money. The first 14 days will cost $1.95 (you can have this refunded if you aren't satisfied). If you forget to cancel that subscription, you will automatically be renewed at a plan that costs $39.95/month.
You can also sign up for $7.95/month, which will save you from the hefty $39.95 monthly cost.
Resume Companion takes care of all the formatting - all you need to do is enter your information in text boxes. It's a fool-proof way to get a good looking resume, although the content is still up to you (they have a link to an expensive resume writing service that starts at $99 if you need help there).
There are 8 templates available to you - from Classic, Harvard, Elegant and Chicago styles to more modern Dublin, Modern, Milano and Park templates which add a splash of color.
