Questions

Do I need to know Arabic already?

No. Every word comes with its transliteration and meaning, so you can start from nothing. If you can already read the script, the Arabic is always there.

Why start with 500 words?

A small set of words makes up a large share of the Quran. Learning the most frequent ones first means you recognise more of every page, sooner.

Which surahs can I learn?

All 114. Open any surah and learn its words ayah by ayah, with each word marked as a noun, verb or particle.

How does review work?

Tadabbur uses spaced repetition: each word comes back just before you would forget it. One review covers everything you have learned, from any surah or topic.

Is my progress saved?

Yes. Sign in and your progress is saved to your account, so it follows you to a new phone.
