What is the best app to read the Quran?

It depends on what you need, because there is no single best app. A good Quran app has accurate Arabic text, a trusted English translation, clear audio, easy bookmarks and no ads in the middle of reading. Try two or three free ones for a week and keep the one you actually open.

What to look for

Accurate text: the standard Uthmani script, ideally in a page layout like the printed mushaf.
Translation: at least one well-known English translation, with the option to hide it when you want to focus on Arabic.
Audio: several reciters, with verse-by-verse playback and repeat.
Bookmarks and resume: the app should remember where you stopped.
Offline use: useful on trains, flights and in poor reception.
Search: to find a verse by word or topic.

Helpful extras for new Muslims

Tafsir (explanations), transliteration and word-by-word meaning can make reading easier while you learn the letters. Don't rely on transliteration forever, though, since it can't capture the sounds of Arabic accurately. If you are choosing a translation, see Which English translation of the Quran should I read?

Apps to try

Widely used options include the Quran.com app (a free app from a non-profit), Quran Majeed and Muslim Pro. Features, prices and ads change often, so check the current version before you commit. Choose one from a clear publisher and compare its text against a printed copy if you can.

Ads and privacy

Ads between verses are distracting, so look for an ad-free or paid option you are happy with.
Check what permissions the app asks for. A Quran reader doesn't need your contacts.
Switch on Do Not Disturb while reading to avoid notifications popping up over the verses.

Reading well on a phone

Reciting steadily is part of the Quran's own advice:

وَرَتِّلِ ٱلْقُرْءَانَ تَرْتِيلًا "And recite the Quran in a measured way." Quran 73:4

So slow down, listen, and follow the words. The Prophet ﷺ said: "The best among you are those who learn the Quran and teach it" (Sahih al-Bukhari 5027). An app is simply a tool for that. A phone isn't a printed mushaf, which is why many scholars say you can read from it without wudu. See Can I read the Quran on my phone without wudu? And if you wonder about carrying it around, see Can I take my phone into the bathroom if it has a Quran app?

Listening counts too. See Is listening to the Quran as good as reading it?

Key points

No single app is best; pick one with accurate text, translation and audio.
Prefer ad-free or low-ad apps and check permissions.
Use transliteration only as a bridge to Arabic.
Recite slowly (Quran 73:4); learning and teaching are rewarded (Sahih al-Bukhari 5027).

Tip: Put your Quran app on your home screen and set a gentle daily reminder. Even five minutes a day builds a lasting habit.
