If you are someone who works on the go then I have found some apps that will work well for creating documents/files. These apps are free and you can connect them to your Dropbox, thus giving you access to specific files and documents. The following apps are ideal for work or school:
1. Notable Notes
2. Access Note, this app is free for a limited time
3. MP3 Recorder
The above apps are ideal for any business person or student who would need to both be able to access and work while on the go.
The following apps are for fun:
1. Bangla Notes
2. Write to light
