Quran app features: a checklist for a reader people trust

Start with a verified Uthmani text

The first feature of any Quran app is a text readers can trust. The Uthmani script (rasm) is the spelling of the Quran used in printed mushafs across the Gulf, and the app should display it from a verified digital source, never from text that was typed, copied from a website or produced by an AI model.

• Choose a known source. Use a verified text from an established source, such as the King Fahd Glorious Quran Printing Complex or a well-established project like Tanzil, and record which version you used.
• State the riwayah. Most readers in the Gulf use Hafs 'an 'Asim. If the app offers others, label them clearly.
• Test the data. Check that every surah has the expected number of ayahs and that ayah numbers, sajdah marks and juz and hizb boundaries match the printed mushaf.
• Lock it down. Treat the text as read-only content; changes go through review, never through an admin edit field.

Aalim, the Quran learning app FLUIDS designed and built, presents authentic Uthmani script in a clean, calm reader. That restraint suits its purpose: the reader is usually the part of a Quran app people open most, and it should feel like a mushaf, not a feed.

Page layout vs ayah-by-ayah layout

Most serious Quran apps need both layouts, because they serve different reading habits. A page layout reproduces the printed mushaf, which matters to people who memorise by the position of verses on the page. An ayah-by-ayah layout reflows the text so each verse can carry its own actions: play, bookmark, tafsir or a note.

Page layout is technically demanding. The well-known Madinah mushaf has a fixed 604-page arrangement, and matching it on screens of every size means either rendering images of each page or using fonts and line data designed to reproduce those exact lines. Ayah layout is simpler to build and scales better with large text sizes, which helps older readers.

Whichever you start with, keep the reader's position consistent when switching modes and between sessions. Losing someone's place in the Quran is a small bug that feels large.

Reciters and audio playback

Audio turns a Quran reader into something people use while commuting, before sleep or while teaching children. A good player lets the reader choose a reciter, play from any ayah, continue to the next surah and follow the highlighted verse on screen.

• Named reciters. Show each reciter's name and riwayah. Aalim offers a choice of reciters, including Al-Husary and Al-Afasy.
• Licensed audio. Confirm the right to stream and download each recording inside an app.
• Verse timing. Follow-along highlighting and repeating a range need timing data that maps audio to ayahs.
• Background playback. Audio should continue with the screen locked, with clear lock-screen controls.

If your audience includes learners, repetition and slower playback matter more than a long list of reciters. We cover those practice features in tajweed learning apps.

Search, bookmarks, highlights and a personal notebook

Readers need to find a verse quickly and return to the ones that matter to them. Search by keyword or ayah number, bookmarks, highlights and a notebook are the features that make an app feel personal.

• Search that understands Arabic. Ignore diacritics, treat the different forms of alef and hamza as equivalent, and handle ta marbuta and ha, so a reader typing from memory still finds the verse. Accept references like a surah name with an ayah number.
• Bookmarks. Let readers keep several named bookmarks, not only a single last-read position.
• Highlights. Highlight whole ayahs rather than arbitrary characters, so highlights survive font and layout changes.
• A notebook. Store reflections linked to a surah and ayah, so they can be found from the verse or browsed together.

Aalim combines these: search by keyword or ayah number, bookmarks and highlights for favourite ayahs, and a personal notebook where reflections on any ayah are organised automatically by surah and ayah. Linking each note to a verse reference, rather than to a page number, keeps notes correct when the reader changes layout.

Werd plans, reminders and offline reading

A Werd is a regular portion of the Quran a person commits to reading, and a reading plan helps them keep it. The plan should start from the reader's goal, such as completing the Quran or a juz within a chosen period, and turn it into a daily portion they can see.

In Aalim, readers set up a Werd to track reading and memorization together, with memorization progress broken down by surah, juz and time spent. Reminders belong with plans, but they need restraint: one well-timed reminder the reader chose is better than several the app decided on. Our guide to Quran habit apps looks at consistency in more depth, and prayer times apps cover notifications tied to the day's prayers.

Offline reading is expected. People read in the car, on flights and in places with weak signal. Aalim makes surahs available offline; for any reader, the text should ship with the app or download once, and audio downloads should show their size and be easy to remove.

Arabic design, translations, accessibility and privacy

The details around the text decide whether readers trust the app. Arabic must be designed right-to-left from the start, with a Uthmani font that renders marks correctly and interface text in a clear modern Arabic typeface. Mirrored icons, digits in the form the reader prefers (Arabic-Indic or Western) and correct alignment in mixed Arabic and English lines all need explicit testing.

• Translations labelled by source. Show the translator and publisher for every translation, and keep translation visually distinct from the Quran text. A translation conveys meaning; it is not the Quran itself.
• Tafsir labelled by book. The same rule applies to tafsir. Our guide to AI tafsir apps explains how to keep AI explanations tied to named sources.
• Accessibility. Support large text, dark and sepia themes, and good contrast. Screen readers handle Quranic text inconsistently, so make audio easy to reach from every ayah.
• Privacy. Reading history, highlights and notes reveal personal devotion. Keep them private by default, avoid advertising trackers, and let users export or delete their data. Saudi Arabia's Personal Data Protection Law (PDPL) applies to personal data; confirm specifics with qualified counsel.

What to put in a first release and what can wait

A first release should be a reader people trust; everything else can be added once that is solid. This table is a starting point for a scope discussion, not a fixed rule:

FLUIDS designs and builds Quran apps for associations, mosques, schools and founders in Saudi Arabia and the GCC. See the Aalim case study, read about launching an Arabic product, or start with the mobile app MVP guide. Our guide to adhkar apps covers a related daily-worship product.
