Editor's Overview

AudioLex is a science & education application developed by Stephan Reindl, packaged as a single Android APK of version 0.4 weighing in at 30.33 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 30.33 MB, so it installs quickly even on modest connections.
This build is signed by "Stephan Reindl" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

AudioLex trains the understanding of spoken words for the case where hearing and understanding come apart: the sound arrives, but it is no longer reliably decoded as speech. That happens after one-sided hearing loss, and a hearing aid alone does not fix it — it makes things louder, not clearer. The path from sound to word has to be practised again.

Two modes, both aimed at the same thing:

Learning mode — a word is played with its text visible. This builds the link between what arrives and what it means.

Exam mode — the word is played, the card stays covered. You rate yourself. That rating decides when the word comes back: after a minute, after ten, after a day, a week or a month.

92 words and sentences are included: 72 in German — 68 from free speech synthesis, four spoken by real voices — and 20 in English. Which language you train is a setting of its own, separate from the language of the interface. Your own recordings can be added: speak a word or sentence, write it down, train it. Several speakers can be kept apart and switched on or off individually — a familiar voice is a different exercise from a stranger's.

For harder practice, put a background noise under the speech and set the distance between the two in decibels. Three levels do it in one tap: easy without noise, hard with a clear speech advantage, advanced with the noise above the speech. One noise is included, recorded inside a bus. Your own can be recorded or imported as WAV files.

For headphone training there is a channel choice — left, right or both — which helps when only one ear should be trained. Over a Bluetooth hearing aid, stereo is summed to mono; the app detects this and shows the channel choice as ineffective instead of pretending otherwise.

What AudioLex does not do: it requests no internet permission, has no account, no trackers, no ads. Vocabulary, ratings and session history stay on the device — not as a promise, but because the app has no technical way to send anything. A backup writes your own recordings, your own noises and the session history to a ZIP file in your documents when you ask it to. What happens to that file afterwards is up to you.

AudioLex is a practice tool, not a medical product. It replaces neither an audiologist's advice nor an ENT examination.

The app was built for one person with exactly this problem. It shows: it is plain, and it does not explain itself — the short guide inside is where it tries. The interface speaks German or English, switchable on the start screen.

Frequently Asked Questions

Is AudioLex free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does AudioLex require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is AudioLex safe to install?
We link to the exact APK published by Stephan Reindl. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update AudioLex?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.
