The BIG4 Office Applications
- Microsoft Office 365 - Subscription Or One Time Payment.
- Pages, Numbers and Keynote - For Mac and iOS Only (sold separately in the App Store).
- Open Office - FREE Open Source.
- Libre Office - FREE Open Source.
If you're looking for simple and FREE Office applications then either Open Office or Libre Office should do you fine. If you're on a Mac or iOS device then Apple's own offerings should do the trick as they integrate brilliantly into the operating system as you would expect from Apple.
A business or professional should probably go for Microsoft Office 365 on subscription basis as this also bundles cloud storage and exchange email services.
