Assalamu alaikum.
Brothers and sisters, jazakumullah for the apps.
I am building a quran course and would love to have my students be able to listen to alquran while looking at word by word of a combination of
  1. Arabic script
  2. Indonesian transliteration
  3. Indonesian translation.
Yes, only the "inline" transliteration in the word by word that is still missing.
I think i ever looked at the apps database in 2018 or so and i found that transliteration is available. I am not sure if it was word by word, but i believe this is only 1 to 1 mapping, not difficult.
I found several apps with transliteration, but none has word by word transliteration like in quran.com if you activate the transliteration.
Insya Allah this will help students to simultaneously hear and see the sound ie the recitation and help them develop connection of audio and visual pathway.
Please have the idea discussed. Jazakumullah brothers and sisters.
