This app works great, but I want to be able to use my own dynamic dns. It prohibits you to enter a URL, only IPs or Paradoxs own DNS solution (free but difficult to set up, you need their proprietary software to set it up on your home pc, which then links it to the DNS service) Dyndns links to my modem, which cuts out the pc. Wonderful for monitoring and arming/stay/sleep arming your alarm. Missing the Bypass feature though, and I need to use it! The app worked fine on iOS4, but started crashing and simply does not work on iOS5. Please fix these few issues, and Ill upgrade it to 5 stars.
