Concise, Curated, and Comprehensive
1) Besides being free, it has no ads,
2) Urdu and English (to learn multi-lingual as you learn the Arabic)
3) its simple to navigate but you can dive deep if you want to learn a verse, a root word, down to the context in time of revelation.
4) Tafseer in both urdu and english - beside each ayah rather than a 2 hour marathon
5) Its pretty. Meaning the curators truly have spent time bolding words, creating tool tips, expanding into tafseer; it all flows gracefully graphically.
SUGGESTION FOR FUTURE: as sincere as your team is to make this free, I would pay to use it offline. Be mindful, as its connected to data/wifi we are interrupted with notifications from other apps. This unfortunatley disrupts the Quranic Hive im building with my Lord - private, peaceful, and often outdoors. I would cherish this immensely and it could generate revenue to further your sadiqa jariya (continuous charity) for other remarkable projects. JazakAllahu Khairan, you gave humanity a gem with this app and glorified Our Lord in ways gratitude (nor my long review) can express :)
