The app is paused for now.
Everything it did, the website does — same rooms, same characters, same reasoning test — with nothing to install.
Use it in the browser instead
It works on any phone, including an iPhone, and on a computer. Open it, sign in, and if you want it to feel like an app, use your browser's Add to home screen — it gets its own icon and opens without the browser chrome.
If you already installed it
Nothing has been taken away from you. The app on your phone keeps working, and your account, your history and your settings are the same ones the website uses — sign in there and everything is where you left it.
Will it come back?
Probably. It is paused rather than cancelled: the work goes into the web version for now, and the Android build gets picked back up when there is a reason to. This page will say so when it does.
Open it in the browser.
Free, in Hindi, Hinglish or English. Nothing to install.
