Download Reflex App

The safe way to get Reflex by Kranus Company is straight from Google Play. The download and install happen on Google Play itself — this page just points you to the right listing, because there are several apps called Reflex and picking the wrong one is easy.

How to download Reflex safely

1. Tap the download button on this page. It opens the official Google Play listing.
2. Check the details before you install: developer name Kranus Company, package name brain.reaction.concentration.
3. Confirm the app is free and about 24.6 MB. Version 14.9 is the current release we checked.
4. Tap Install on Google Play and let Play handle the download. You get updates through Play automatically.

Why we only link to Google Play

APK download sites copy app names and icons, and several of them list outdated or repackaged files under the Reflex name. Some add extra software you never asked for. The Play listing is the one the developer controls, so the file you get is the file Kranus Company published, scanned by Play Protect before it lands on your phone.

If a site offers you a "Reflex APK" with a different package name, close the tab. The real package is brain.reaction.concentration. That one detail separates the genuine app from its namesakes, including Reflex!, ReflexTest and RTap, which are separate apps from other developers.

After you install

Open the app and run one reaction test straight away to set your baseline score. Around 250 milliseconds is average for a visual cue, so do not worry if your first numbers sit there. Then try the reflex training routine for improving reaction time for a week and test again. Short daily sessions, same time of day, same phone — that is how you get a trend you can trust.
