About

Instant Zmanim

Features
Read full description

There are some excellent and very well-made Zmanim apps out there that have lots of features and special customizations. This app is not one of them. Instead, it aims to be able to quickly get a glimpse of the daily zmanim for the area. As of this first release, please be warned that the zmanim have not been verified and should be treated as approximate times. This app should not be relied upon for exact halachic times. Please confirm these times with another more well established zmanim calculator, or check the times of your local community. There are plans to improve accuracy and verify in the future.
