Newsflash, Android users: the Google Drive/Docs app is terrible. It's just about competent enough to read the documents you've written elsewhere, but for editing and creating new Word, Excel, and PDF documents, you need something with a little more oomph. One of the best choices out there is OfficeSuite, and it's also one of the most expensive, at $15. But right now you can - and should - pick it up for a single dollar.
If you missed out the last time OfficeSuite Pro 6 was on sale for $0.99, you can stop being sad now - it's back on sale until July 4th! OfficeSuite Pro is my personal favorite office suite for Android, as its blend of excellent features, intuitive and easy to use interface, and cloud storage integration (yes, I did quote myself there), make it as top-notch of a choice that you'll find on the Store.
I'm not going to lie: I have an unhealthy obsession with mobile office software. I've tried nearly every one available in the Play Store, but I keep coming back to OfficeSuite Pro. Its blend of excellent features, intuitive and easy to use interface, and cloud storage integration (Box, Dropbox, SugarSync, and Google Drive) makes it my personal favorite document, spreadsheet, and presentation editing software for my Android devices.
For a limited time, you can snag this excellent office suite for a mere $0.99 - a full $14.00 off of its regular price.
