Notes for iPad users:

  • Help files are not supported for the iPad version, so this version is most appropriate for experienced CRW users.
  • The iPad version does not allow Excel data exports.
  • Data entered on a Windows PC or a Mac can be used interchangeably between platforms. For example, a facility that creates mixtures, adds custom chemicals, etc. can copy the PC or Mac runtime file containing all of their customized work to the iPad version and have all of that work available there.
