Adobe Acrobat Reader for iOS enables you to view, annotate, and sign PDFs from your phone. Subscribe for a free Adobe Document Cloud account, or connect to another online storage account like Dropbox, and work across all your devices.
Annotate, fill, sign, and send PDFs: Adobe Acrobat Reader for iOS provides all these tools for free. You'll have to pay for premium features like converting PDFs to Word or Excel, unlimited conversions from mobile, exporting PDFs to Word or Excel, or editing and reorganizing PDF pages. But most users will not need these.
Access PDFs across devices: Connect Adobe Acrobat Reader to Adobe Document Cloud or Dropbox and access files from anywhere.
Scan to PDF: Capture anything from a Word document, whiteboard, or receipt with your camera and easily convert it to a PDF.
Easy to navigate: All the tools you need are in a single menu. Just press the Home button to open.
Costly extras: Adobe Acrobat Reader for iOS performs most functions you need for free. But power users may find advanced functions cost prohibitive. An Adobe Acrobat DC subscription, for example, costs $24.99 per month. What's more, Preview and Foxit PDF offer some of these tools for free.
Adobe Acrobat Reader for iOS should be your go-to app for reading and doing much more with PDFs.
