I wanted to set one my other apps to follow the same timings as my local mosque, but they only allow you to choose between groups like ISNA or MWL ect. This is the only app I found that allowed me to simply look up my mosque, and presto the timings came exactly the same as my mosques. Theres also a nice intro section where you can read all sorts of info regarding how the timings have been calculated from past till present.
