I found a mistake in your Quran app.
In Surah Yasin:
This is in ur app:
While this is in Quran:
I was doing a wazeeda in which i had to read this Ayat 11,000 times and i conpleted 4,000 times. Just because of ur mistake i did not pronounce it right and i have to start it again. I purchased a paid app and still there is mistake.
