Editor's Overview

Numerus is a science & education application developed by Konstantin VERNER, packaged as a single Android APK of version 2.0 weighing in at 15.21 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 15.21 MB, so it installs quickly even on modest connections.
This build is signed by "Konstantin VERNER" — 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

Oral comprehension of numbers in foreign languages can be challenging. Here’s why:

1. Frequency of numbers in ordinary discourse is usually low, so learners struggle to develop a habit of listening to numbers.
2. Most words are easy to recognize due to context, whereas numbers are isolated. For example:
With a population of 8 804 190, New York City is the most populated city in the US.
The context helps only a little: you can guess millions, but thousands are essentially random.
3. Some languages construct numerals differently. For example, how to say 95:
English: ninety five (90 5)
German: fünfundneunzig (5 and 90)
French: quatre-vingt-quinze (4-20-15)

The best way to train comprehension is frequent exposure to numbers in real speech. This app provides that:

1. A random 10-second clip from a video plays and repeats.
2. The user types the number they heard and taps “check”.
3. Subtitles appear and the app shows whether the answer is correct.
4. The user taps “next” to continue.

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 Numerus require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is Numerus safe to install?
