How Tezeract Rebuilt an AI-Powered Digital Reading App Across Three Platforms With Bilingual Urdu Search and Unified Subscriptions

Impact

Project Overview

AdeebOnline was already live, a digital reading platform with an existing user base on the app stores. But the legacy app had outgrown its architecture. The tech stack was outdated, the admin panel lacked the controls a growing catalog needed, and the user experience did not reflect what modern readers expect from a digital transformation of a publishing platform.

Fasihuddin Ahmed, a Karachi-based IT professional, needed a complete rebuild – not a patch. A new cross-platform book reading app for Android and iOS, a responsive web application, and a purpose-built admin panel, all running on a re-architected database that preserved every existing user account and book in the catalog.

Tezeract took the project from discovery to production across twelve structured milestones, delivering a unified ebook platform development effort that included bilingual search (Roman Urdu + Urdu), four-tier subscriptions across three payment gateways, offline reading on mobile, cross-platform deep-link sharing, and an admin panel with nine sort options, analytics dashboards, and broadcast notifications.

What Changed

Readers no longer use a dated app with limited features and no web access. AdeebOnline is now a modern, cross-platform book reading app where users search in Urdu or Roman Urdu, read with customizable themes and persistent zoom, bookmark pages with notes, download for offline reading, and share specific book pages with anyone, whether or not the recipient has the app installed.

Why This Matters for Buyers Like You?

If you have a live app with an existing user base that has outgrown its tech stack, you know the risk: rebuild wrong and you lose users. Rebuild too slowly and the market moves on. AdeebOnline’s challenge is common across digital publishing, edtech, and content platforms: a legacy product that works but cannot scale, support modern UX expectations, or expand to new platforms without a ground-up rearchitecture.

The question is not whether to rebuild, but how to do it without disrupting what already works.

Rebuilding a Live Digital Reading Platform Across Three Surfaces Without Losing a Single User or Book

Primary Problem

The existing AdeebOnline app was functional but architecturally limited. The tech stack was outdated, the database schema could not support the features required by a modern Urdu reading app development effort, and there was no web version or proper admin panel. Readers were stuck with a basic experience, no bilingual search, no bookmarks with notes, no offline downloads, no cross-platform sharing. The admin had no analytics, no book-sequencing controls, and no way to efficiently manage a growing catalog.

The core challenge was a full mobile app rebuild – replacing the entire product across Android, iOS, and web while preserving every existing user account, subscription, and book in the catalog. One unified database, three client surfaces, zero data loss.

Secondary Challenges

No web presence

The platform existed only as a mobile app. Readers without the app had no way to access the library, and shared links led nowhere for non-app users.

Legacy database limitations

The existing schema could not support new features like bookmarks with notes, bilingual search, analytics tracking, or multi-gateway subscriptions without a full rearchitecture.

No admin tooling

The client had no proper admin panel, no book sequencing, no featured tagging, no broadcast notifications, and no user or book analytics.

Payment fragmentation

Supporting Google Pay, Apple Pay, Stripe, and local Pakistani payment rails like JazzCash, etc under a single subscription state machine with consistent grace periods and cancellation flows was a significant integration challenge.

Bilingual search complexity

Roman Urdu and Urdu use different scripts and transliteration patterns. Most off-the-shelf search libraries do not handle this combination well.

Still Running a Legacy App That Can’t Scale?

AdeebOnline faced the same challenge. An outdated architecture, limited functionality, and growing user expectations made expansion difficult. Tezeract rebuilt the entire platform across mobile and web while preserving every user account, subscription, and book. If your product has outgrown its technology, we can help you modernize it without disrupting your business.

What Slowed Down Operations and Triggered the Need for Immediate Change

Previous Solutions Tried

The application was already built and live on the stores with an active user base. The client was not looking for a new tool, he needed a complete new version of the existing product with a modern tech stack, improved UX, optimized performance, and a newly built admin panel. No off-the-shelf solution could deliver this because the rebuild had to preserve existing data while fundamentally changing the architecture.

Business Impact

Without the rebuild, AdeebOnline was stuck. The legacy app could not support the features readers expected, bilingual search, offline downloads, bookmarks, web access. The lack of an admin panel meant the client had no visibility into user behavior, no control over catalog presentation, and no tools for engagement. Growth was capped by the limitations of the old architecture.

Urgency Factors

The existing user base expected a better experience, competitor reading apps were setting higher UX standards in the market
No web version meant losing potential readers who discovered books through shared links but did not have the app installed
Local payment gateway integration (JazzCash) was essential for the Pakistani market where international cards are not universally available
The longer the rebuild was delayed, the more technical debt accumulated on the legacy system

Why Tezeract

Fasihuddin needed a team that could handle the full scope, mobile app development for Android and iOS, a responsive web app, an admin panel, database migration, payment gateway integration, and bilingual Urdu support, under one roof, on a predictable timeline. This was not a feature addition. It was a ground-up rebuild of a live product with real users.

Why Tezeract Won the Evaluation

Tezeract’s structured milestone-based delivery model gave Fasihuddin the predictability he needed, clear timelines, built-in feedback checkpoints, and a discovery-first approach that prevented mid-build surprises.

The team’s experience with cross-platform product builds, payment integrations, and localization for regional markets made them the right fit for a project that required both technical depth and product sensitivity.

AdeebOnline, A Cross-Platform Digital Reading App Rebuilt for Modern Urdu Readers

AdeebOnline was rebuilt from the ground up as a unified ebook marketplace development project, three client surfaces (Android, iOS, web), one backend, one database, and a purpose-built admin panel that gives the client full control over the catalog, users, and engagement.

The platform serves Urdu readers with a reading experience designed specifically for the language, bilingual search across Roman Urdu and Urdu, right-to-left layout support, and a reading panel built for long-form Urdu content with persistent zoom, light/dark themes, and page-wise sharing.

How AdeebOnline Works

A reader signs up using custom credentials, Google Sign-In, or Apple Sign-In. The landing screen presents the book catalog with category filters, admin-controlled sort order, and featured book highlights. The bilingual search engine handles queries in both Roman Urdu and Urdu across titles, keywords, authors, and publishers.

Opening a book shows metadata, category, page count, reads, reviews, and ratings. Premium subscribers can download for offline reading; free-tier users read online. The reading panel supports light and dark themes, persistent zoom across pages, vertical scroll, bookmarks with notes, and page-level external sharing via deep links.

Subscriptions are managed through a unified state machine spanning Google Pay (Android), Apple Pay (iOS), Stripe (web), and JazzCash (local). Plan upgrades, card updates, grace periods, and cancellations behave consistently regardless of which gateway the user subscribed through.

Phases wise Deployment

Tezeract delivered AdeebOnline across five phases on a twelve-milestone schedule, with each milestone running on a two-week cadence and closing with a structured client review checkpoint.

Discovery, Design & Architecture

Reviewed the legacy GitHub repos and mapped the existing database. Generated new UI/UX in Figma for all three surfaces – mobile app, web app, and admin panel. Produced the new database schema, full API listing, and both high-level and low-level architecture documents. Following a thorough UI/UX design process before writing any feature code prevented downstream rework and aligned the client on scope.

Key milestone: Complete design system, schema, API listing, and architecture approved before any feature development began.

Mobile App Core Development

Built the full mobile app feature set: authentication, landing screen with filters and bilingual search, book detail screen, reading panel with themes and persistent zoom, profile, library, request-a-book, reviews and ratings, settings, help center, feedback module, terms and privacy screens, and initial payment gateway integration.

Key milestone: Fully functional cross-platform book reading app with core reading experience and user management complete.

Payment Completion & Admin Panel

Completed Google Pay and Apple Pay integration across Android and iOS. Built the admin dashboard with category-wise book sequencing, featured-book tagging, broadcast notification dispatcher, and analytics dashboards. Integrated OneSignal for push notifications on both the app and admin sides, plus the in-app notifications screen.

Key milestone: Monetization layer live with admin panel providing full catalog and user management control.

Client Feedback, QA & App Store Launch

Dedicated testing-and-feedback window. Regression testing across app and admin, bug fixes based on client review, App Store and Play Store submission, addressing store review feedback, and verifying live listings.

Key milestone: AdeebOnline live on both the Apple App Store and Google Play Store with verified listings.

Web Application Build & Launch

Built the web UI/UX, adjusted schema and APIs for web-specific requirements, and delivered full feature parity, auth, landing, book detail, profile, reading panel, library, favorites, bookmarks, downloads. Integrated Stripe for web payments and JazzCash for local Pakistani buyers. Regression testing and production go-live.

Key milestone: Responsive web application live at adeebonline.com with Stripe and JazzCash payment integration.

Key Features

Bilingual Search

A custom-built search engine that handles both Roman Urdu and Urdu script inputs across titles, keywords, authors, and publishers. Most reading apps in this market default to English-only or single-script Urdu, AdeebOnline supports both, making the catalog accessible to readers regardless of how they type.

Cross-Platform Reading Panel

Light and dark themes, persistent zoom across pages, vertical scroll, continue-from-last-position, and page-wise external sharing. Designed specifically for long-form Urdu content with RTL layout support, not a generic reader retrofitted for a different script.

Bookmarks With Notes

More than a save button. Readers can bookmark any page and attach personal notes, turning the library into a study and reference tool. All bookmarks, downloads, and favorites are unified under “My Library” across devices.

Unified Subscription System

Four premium tiers with consistent behavior across Google Pay, Apple Pay, Stripe, and JazzCash. Plan switching, card updates, grace periods, and cancellations work the same way regardless of which gateway the user subscribed through. Region-aware pricing adjusts currency and amount based on user location.

Cross-Platform Book Reading App for Educational Institutions

Schools and universities looking for a cross-platform book reading app to distribute course materials can leverage the bookmarks-with-notes feature, offline downloads, and admin-controlled catalog sequencing to create a managed reading environment for students. This approach aligns with broader e-learning app development strategies.

Digital Publishing for Multilingual Markets

Any publisher operating in a multilingual market, where readers type in transliterated scripts, local scripts, or both, can use AdeebOnline’s bilingual search architecture as a blueprint for making their catalog truly accessible.

Frequently Asked Questions

What does it take to rebuild a live app without losing existing users?

A successful mobile app rebuild starts with a thorough discovery phase, mapping the existing database, understanding the current data model, and designing a migration strategy that preserves every user account, subscription, and content record. AdeebOnline’s rebuild migrated all legacy data to a new schema without disrupting existing users.

How does a cross-platform book reading app maintain consistency across Android, iOS, and web?

By running all three client surfaces on a single unified backend and database. This ensures that a user’s library, bookmarks, reading progress, and subscription status remain consistent across platforms. Platform-specific differences are handled at the client level, not the data level.

What is involved in ebook platform development with multiple payment gateways?

Each payment gateway (Google Pay, Apple Pay, Stripe, JazzCash) has its own subscription lifecycle, webhook structure, and edge cases. The key is building a unified subscription state machine that normalizes these differences, so plan switching, grace periods, card updates, and cancellations behave consistently for the user regardless of which gateway they subscribed through.

How does bilingual search work for Urdu and Roman Urdu?

Most search libraries are built for Latin scripts and do not handle Urdu’s right-to-left script or the transliteration patterns of Roman Urdu. AdeebOnline uses a custom-built search engine that indexes titles, keywords, authors, and publishers in both scripts, allowing readers to search in whichever format they naturally type.

Why is a discovery phase important before rebuilding a digital product?

Investing in schema design, API listing, and architecture before writing feature code prevents expensive mid-build pivots. AdeebOnline’s three-week discovery phase meant the team validated the data model, designed all three surfaces in Figma, and aligned with the client on scope before any development began, thereby eliminating downstream rework.

Can a freemium subscription model work for digital publishing?

Yes, when the free tier provides genuine value and the premium tiers unlock meaningful upgrades (full catalog, offline downloads, expanded access). AdeebOnline’s four-tier model with region-aware pricing makes premium accessible across different markets while maintaining a clear value ladder.

How long does it take to rebuild a cross-platform digital reading app?

AdeebOnline was delivered across 12 milestones at a two-week cadence, with discovery to web launch taking approximately 6 months. The timeline depends on scope, but a milestone-based approach with built-in feedback checkpoints keeps delivery predictable and the client aligned throughout.

What makes AdeebOnline different from generic ebook apps?

Three things: bilingual search that actually works for Urdu and Roman Urdu, a reading panel designed specifically for long-form Urdu content, and cross-platform deep-link sharing that routes non-app users to the web version without losing context. It was built for Urdu readers, not adapted from an English-first template.
