the author of this app says:
iZman calculates prayer times, or Shaot Zmaniot, used by Jews worldwide to determine when to pray.
In this version of the app, users can select their location from a predetermined list, or use their iPhone's GPS to automatically give them prayer times based on their geographic location.
Our next update will include more cities and the ability to add custom cities.
- Requires iPhone OS 3.0 or later.
