I am writing because I use your application regarding prayer times and I have a concern about your calculation of al fajr prayer. I have heard many Muslim scholars talk about thruth fajr (assadik) and the wrong fajr (al kathib) and I also learned that there is a gap of 30 minutes between them. I do not know if you understand what I'm talking about and if in your calculations, you took into consideration these religious criteria?
I would appreciate your answer, it is a big burden for me and I do not know how to solve it.
Thank you for your cooperation on this.
