The app keeps ASPRS competitive and continues to provide members with the tools they find essential, such as real-time access to association news, member directories, information on ASPRS webinars and conferences, and critical industry alerts all from their iPhone or Android smartphone. The app is available on both iPhone and Android platforms. Now everyone can have the association The Conference side of the app allows Downloading the new ASPRS app is experience right at their fingertips.
