Laptop computers are great tools both in and out of the classroom. But they are bulky to carry around morning, noon and night. Leave your laptop behind and still get heavy writing and note-taking done on your Android phone or tablet.

All you need to convert your tablet or smartphone into a top-grade learning tool is a comfortable Bluetooth keyboard and a good, free writing app. Add an audio recording app to further increase portability.

Check out this list of the best writing tools for smartphones and tablets. These apps are free, flexible, and compatible with the Microsoft Office suite. Pair them with a free cloud storage service such as Dropbox or Google Drive and access your assignments wherever you are on any device—mobile phone, tablet, laptop, or desktop computer.

Polaris Office

Polaris Office is among the most reliable mobile writing tools out there, and its features are impressive. Use it to convert documents to PDF on your smartphone or tablet or add notes in PDF documents. It also features presentation tools that allow you to organize key information and create or edit content for group presentations using 37 slide transition effects.

If your learning style involves study groups, you can share documents via email, instant messaging, and social media messaging. It even works with Google Chromecast, as well as cloud services like Google Drive, Amazon Cloud Drive, Drop Box, OneDrive, and more.

This Android app includes more than 300 formulas for math and finance. It has 24 templates, 20 2D/3D charts, and 173 different shapes.. All of this is free. For $3.99 to $5.99 per month, you can upgrade to more features in the Smart and Pro versions.


WPS Office

WPS Office automatically synchronizes your files with Google Drive and Dropbox and can access documents stored on Box, OneDrive, Evernote, and FTP/WebDAV. This Android writing app is completely free and offers in-app purchases that expand the functionality. But the free version is fully capable of letting you get your assignments (and a lot more) done. If your mobile device is running out of storage, this is a app to get around it. At 25MP, it is one of the smallest on the market.

Its features compare nicely with Polaris Office. For instance, it includes Writer, Presentation, and Spreadsheets modules and lets you encrypt your documents to protect your work. It works effortlessly with USB and Bluetooth keyboards and uses many of the same keyboard shortcuts you use on a standard computer, such as Ctrl+C for copy and Ctrl+P for paste. Plus, WPS Office has many of the features you use in a PC office suite. These include advanced text and paragraph formatting options and the ability to add and edit images, shapes, tables, and charts directly into your presentation or document.

Jotterpad

 JotterPad is one of my favorite writing tools for taking notes and cranking out content on my  smartphone and tablets. The only drawback is the lack of a JotterPad program that runs on a  standard desktop or laptop computer. But when I work on a computer, I can still load the  JotterPad file and continue where I left off because JotterPad is fully interchangeable with  Microsoft Word.

Writer specializes in text—it has no presentation or spreadsheet modules. It’s a minimalistic text  editor that is perfect for any type of writing task and note-taking. Its user interface and feature  set are likely very familiar to whatever word processor you use on your computer.

I use JotterPad as a makeshift database and planner. First, I set up a document for each topic  and task. Then I save the entire collection of notes to a folder in my cloud storage. JotterPad  forms an index with search capability, and soon all of my files are also accessible in the cloud  storage folder installed on all of my computers and mobile devices. Accessing my information  could not be simpler or more reliable. Plus, whatever device I use, all of the files remain up to  date.
