Notes (included in the help.htm):
From my experience, the calculation for Asr prayer time sometimes 15-30 minutes earlier. At least in my home country. Maybe different in your country, so just brace yourself and try it out ;0
   I think this app. has the most complete feature set than other FREE apps in this category. But in terms of accuracy I recommend: Shollu, Athan Basic, Muslim Prayer Times, or Munadi.[]
