Question 1

Is it really free? No hidden charges?

Accepted Answer

100% free. No in-app purchases, no subscriptions, no ads. The app uses Google's Gemini API with your own free key. Free as long as Google AI Studio stays free — which it has been since 2023.

Question 2

What is a Gemini API key and why do I need it?

Accepted Answer

A free key from Google AI Studio that lets the app generate fresh AI questions. Takes 2 minutes to set up, no billing needed. Go to aistudio.google.com → Get API Key → Create → copy and paste.

Question 3

Why APK and not Play Store?

Accepted Answer

Play Store approval takes time. The APK installs directly in 30 seconds. Enable 'Install unknown apps' in Android settings, install, done.

Question 4

Which engineering branches are supported?

Accepted Answer

Mechanical, Electrical, Civil, Chemical, Electronics, Computer Science and more. Questions generated specifically for your branch — not generic.

Question 5

Will questions repeat across sessions?

Accepted Answer

No. The app tracks every question you've seen and tells Gemini to avoid them. Every session has fresh questions.

Question 6

Does it work offline?

Accepted Answer

Partially. Bookmarked questions and insights are available offline. AI question generation needs internet to call the Gemini API.

Question 7

Is my API key safe?

Accepted Answer

Yes. Stored locally on your device using encrypted secure storage. Never sent to any server — not ours, not anyone's.

Question 8

Which engineering exams are covered?

Accepted Answer

GATE, IES/ESE and PSU recruitment exams — HPCL, Coal India, BHEL, ONGC, NTPC, SAIL, IOCL, GAIL, BPCL and more. Interview Simulator available for exams with GD/PI rounds like HPCL, BHEL and IES.

Question 9

Is Aspirant Arcade only for engineering exam aspirants?

Accepted Answer

No. Class 9–12 students can practice CBSE/NCERT chapter-wise MCQs, True/False challenges, and Match the Following across Science, Maths, Physics, Chemistry, Biology, SST, and English. Select Schooling on the home screen after downloading.

Question 10

Do I need a Gemini API key to play?

Accepted Answer

No. You can play immediately from our shared question bank — no key or signup required. Adding a free Gemini key (Google AI Studio, 2 minutes, no billing) unlocks unlimited freshly generated questions every session.

Question 11

What is Focus Mode?

Accepted Answer

Focus Mode is an Android-only feature that catches you on Instagram Reels or YouTube Shorts and makes you clear a few MCQs from your branch and syllabus before you can keep scrolling. You set the scroll limit and how many questions, and you can turn it off anytime. It turns doom-scrolling into drip-fed revision without quitting the app.

Question 12

Does Focus Mode read my messages or spy on me?

Accepted Answer

No. It only checks which app is open and the screen name (Reels or Shorts) — like a sign on a door, not what's inside the room. It never reads your DMs, captions, comments or the videos themselves, and nothing leaves your phone. Questions are cached locally on your device.
