Having been a Pageonce user since their initial beta releases, I have to say, while this was a long time coming I'm sure as heck happy to see it. Pageonce has released version 2.5 of their Personal Assitant application and with this release they have indeed added push notifications to the mix.
Now as your customized accounts have changes happen, you are instantly notified of what went on. Anything from flight changes, bills that arrive or even credit card transactions. It all is captured for you and delivered to your device so that you can quickly and accurately keep track of the things that are important to you. The basic Personal Assistant is made available for free while premium services with added features are available for only $6.99. Both of which offer the email alert system.
