Seeking Islamic Guidance on Using a Real-Time Silent Transcription App for Salah and Khutbah

Assalamu Alaikum wa Rahmatullahi wa Barakatuhu, My name is Rishan Kahar, and I am a Muslim student and developer currently working on an Islamic educational application aimed at helping: Beginner-level Muslims understand what is being recited during Salah (prayer) by displaying real-time silent transcription and translation of the Ayahs on their mobile screen. Non-Arabic speaking Muslims (especially foreigners living in Arab countries) understand the Friday Khutbah (sermon) by providing real-time text transcription and translation into their preferred language, silently, as live on-screen text. The purpose of the app is purely educational and spiritual—to support understanding and connection during worship for new Muslims or learners. My two respectful Fiqh-related questions are: Is it Islamically permissible for a beginner-level Muslim to look at their phone screen during Salah to view silent, real-time text translations of what is being recited (only for learning purposes while they are still memorising and understanding the prayer)? Is it allowed for a person to view silent real-time text translations of the Khutbah on their phone screen while listening attentively, especially when the sermon is in Arabic and the person is not fluent or a non-Arabic speaker? In both cases, the app does not play any audio, and the screen can be dimmed or simplified to avoid distraction. The goal is not to change the structure of Salah or Khutbah but to support understanding for those who are still in the process of learning. I would be grateful for your scholarly guidance to ensure this project remains fully respectful of Islamic teachings and boundaries. Jazakum Allahu Khairan for your time and consideration.
