Master Mental Ability — training the reasoning behind almost every exam. First, which one's yours?
Pick one — the page will speak to your exam.
Whatever you prepare for — Railway, SSC, Banking, CUET, CAT, placements — reasoning is the section underneath. Build it now; it transfers to all of them.
Free to try.
Different exams, different names — the same two families of reasoning underneath.
The same reasoning runs under every one of them. Master it once.
A system that adapts to you — so your time goes where you actually need to grow, not just where you're weak.
Harder questions as you improve, easier when you slip. Your time goes where it grows you most.
Brings a question back right before you'd forget it — so it actually stays.
You reason it out first, then see the answer. That effort is where learning sticks.
A moment to settle before you start. Less anxiety, more focus.
On Android, all the questions live on your phone, so after install, daily practice costs zero data. The app needs the internet once to start, then at least once a week. In the web app, on a phone or computer, you practise in the browser while you are online.
No account, no card, no install. Solve one full session, then decide.

Proven by the research on how learning works — and built by someone who's spent two decades in it.
In 2007, in his second year at IIT Delhi, Vineesh wrote a book — Master Mental Ability in 30 Days. It has sold year after year ever since, without the publisher ever marketing it.
In the years since, he built other learning products and spent a decade working with children and young adults from every kind of background in a holistic learning centre.
This app goes far beyond that book — a different, living thing. Everything he's learned about how people actually learn, built into something you practise, not just read.

Worthy but short on money? Register in the app, then apply from there — means is never the barrier.
No catch. It's free to try — no registration to start, no payment, no auto-debit. When you want the full library there are three plans, by length: ₹499 for three months, ₹699 for six, ₹999 for a year. Each is a single payment for that period, not a subscription — when it ends we ask you, and nothing is ever taken automatically.
PDFs give you material. This gives you the method — the right practice, at the right time — that actually builds the skill. And right now, it's free to try.
Any exam that tests verbal or non-verbal reasoning — RRB, SSC, Banking, NMMS, CUET, CAT, campus placements, defence and more.

Yes. The Android app works offline: the questions live on your phone, so practice uses no data. It needs the internet once to start, then at least once a week. It is in beta for now: join in two steps. You can also practise in the web app, in the browser on your phone or computer, while you are online.
It's free to try while we build. Later, a one-time paid version unlocks the full, growing library — but you'll always be able to try before anything.
Ask it here. Send it by WhatsApp or by email — whichever you have — and it arrives with your question already written. We usually reply within a day.
