There’s no shortage of iOS file-viewer apps out there, but TechCrunch drew our attention to Doctape Viewer, a freemium app which claims to support more file formats and more cloud services than any other. The app enables you to view more than 80 different types of file, spanning office documents, images, audio, video and more.

The free version of the app offers two conversions per day, with unlimited conversions available via a $0.99 upgrade to the Pro edition. You do, though, need a net connection as the conversion is cloud-based, using the conversion engine from the company’s own cloud storage service doctape – files to go.

Supported file formats include:

  • Adobe PDF files (PDF)
  • Microsoft Office files (Word DOC/DOCX, Excel XLS/XLSX, Powerpoint PPT/PPTM/PPTX)
  • Libre Office & Open Office files (ODT, ODT, SXW, STW)
  • Text-files (RTF, TXT, CSV)
  • Audio files (MP3, M4A, AACF, AIFF, WAV, ALAC)
  • Video files (MP4, MOV, MPV, M4V, 3GP)
  • Image & vector files (JPG, PNG, TIF, BMP, AI, NEF, ARF)
  • Adobe Photoshop files (PSD)

The app is available from iTunes.
