Assalamualaikum wa rahmatullah, may Allah be pleased with you. Ruling on prayers that were prayed before due time due to false information (such as isha or fajr because the apps have different timings) do we have to repeat oder does it fall under the rule of ignorance. Jazakallah kheir

It seems to me like you just relied on the application (correct me if I am wrong) and you haven't investigated enough. There are so many means that you can take. Therefore, you should repeat these prayers, inshallah.
