Asalamualekum :
This app would help you take care of your salah only if you are willing to do so. Nothing else then you yourself can take care of your salah and other ehkaam. As ALLAH subhanawatallah has given us tremendous niyamat for our wellness and also he has gifted us some duties in form of salah(Namaz) and roza. They are two of the most important aspects of our day to day life. And most of us try to take full advantage of these beautiful gifts. But sometimes due to any difficulties or due to lack of will or by the actions of Shaitaan Mardood we get distracted from the right path (Sirat-e-mustakeem).
