Zmantime (Alarm) Clock for Android

By Aba Zman Apps Free

Developer's Description

The Zmantime Alarm Clock app is a world first - a clear and well-designed sha'ot zmaniot (Jewish halachic time) alarm clock, with home screen widget to show the time in halachic time (what we've called ZmanTime) AND the ability to set alarms based on the shaot zmaniot time so that you never miss a zman again whether at home traveling or when the clocks change.

The alarm feature is the key - for Zmantime alarms automatically adjusts to your location and the changing seasons, so you can set an alarm, e.g. to alert 30 minutes before shkia every day (or on selected days), and it will AUTOMATICALLY adjust to seasonal daylight changes or if your location changes.

Latest revision (1.1) includes the following improvements:

Improved location search efficiency; Adjustment of 'play when on silent' to include meeting/vibration only settings, and general improvements to app functioning.

Major features of ZmanTime Alarm Clock app:

** Built-in and customisable sha'ot zmaniot alarms

** Clear home-screen Sha'ot Zmaniot clock widget to view Jewish time, in real-time (NOTE: due to an android limitation on loading widgets from external storage (e.g. SD card), please ensure the app is installed on Internal Storage for the widget to function properly.

** Toggle between GRA and Magen Avraham opinions

** Updates and synchronises via mobile network or GPS

** Automatically adjusts to new locations and time-zones (advises when not synchronised to avoid mistakes).

** List of zmanim for next 3 days at current location

** Contains descriptions of how Zmanim are calculated, including brief details on the major opinions, and how the Zmantime widget works. (This section to be greatly expanded in future versions).

**** Next version to include calendar reminders for significant upcoming dates, such as fast days and Rosh Chodesh, as well as other additions and improvements ****

The ZmanTime app calculates all zmanim using the kosherJava zmanim API, with much thanks and appreciation due to the guys at Kosher Java for enabling the development of apps like this and general assistance with Judaism observance (

If you have any questions about how the zmanim are calculated on the app, or other zmanim-related requests please read our explanatory sections and/or send your questions on to us and we'll answer whenever we can (for any halachic decision please consult a competent halachic authority).

Note: we have calculated zmanim based on sea level altitude and average atmospheric conditions, so you may find up to 2 minutes discrepancy with alternatively calculated times, depending on altitude and conditions used in the calculation.
