OffWave
PWAListen to the Qur'ān offline, without ads — on any device, with real volume control and zero tracking.
The Problem
Listening to the Qur'ān at night without disturbing family sounds simple, but most apps and sites fall short in one of several ways: they require an internet connection, they show ads, they track usage, or the phone's lowest volume setting is still too loud. This last issue is common enough that it comes up repeatedly on Reddit, Quora, Android forums, and OnePlus community threads, where the usual suggested fixes are workarounds like using Samsung SoundAssistant or covering the speaker with tape rather than an actual solution. Quran.com handles translation and reading excellently, but its audio requires streaming, which does not work on a plane, in a tunnel, or in airplane mode at 3am.
The Solution
OffWave is a Progressive Web App built to solve these problems directly: real volume control from 0% to 200%, complete offline playback after the first load, and zero tracking or ads. As a PWA, it installs from a single link on iPhone, Android, Windows, Mac, Linux, and ChromeOS, one codebase running everywhere. Imported audio files stay on the device in the browser's local database; nothing uploads anywhere. OffWave is a generic audio player, built with Qur'ān and halal audio in mind, but what a user chooses to load into it is entirely up to them.
Key Features
OffWave works fully offline after the first load, including on airplane mode, in tunnels, or with no signal, since files never leave the device. Volume ranges from 0% to 200%, letting users go below their phone's system minimum for quiet night listening or boost above 100% with a soft limiter for quiet reciters. Built-in bass, echo, and reverb effects run in real time and fully offline. There is no tracking and no accounts: no sign-up, no cookies, no ads, only a small privacy-respecting visit counter with no visibility into what anyone plays. The app installs on any device via "Add to Home Screen" for a native-app feel from one codebase. Lock-screen controls support play, pause, skip, and seek directly from the lock screen and notification shade, similar to Spotify or Apple Music.
Technical Details
OffWave is built as a Progressive Web App using HTML, Tailwind CSS, and JavaScript. Offline functionality and audio storage rely on the browser's local database, keeping all imported files on-device. Real-time audio effects (bass, echo, reverb) and the extended volume range are handled client-side via the Web Audio API. Lock-screen media controls are implemented through the Media Session API. The single codebase is installable across iPhone, Android, Windows, Mac, Linux, and ChromeOS without app-store distribution.
Impact
OffWave was built first as a personal solution to a specific, recurring problem: listening to the Qur'ān quietly at night without ads, tracking, or an internet connection. It reflects the same philosophy behind other MZift Islamic tools — free forever, privacy-respecting by design, and built to solve a real problem rather than to accumulate features.
