Reviewers largely see Fajr Calendar as a simple, practical way to block prayer times on their calendar and avoid clashes with meetings, calls, and other work commitments. Many say it helps them plan busy days, stay consistent with prayers, and reduce interruptions. Users also praise the ease of setup, clean design, and helpful options like reserving prayer duration, location-based time updates while traveling, and alarm or Athan settings. The only real criticism is indirect: several reviewers are mainly hoping for future updates rather than pointing to current flaws.
