Questions and answers

A learning app for school students. Every day it gives you a few short questions for your subjects and grade, explains every answer, and rewards you with XP, IQ and badges. There are six games, friends, duels and races, live classrooms and a league for your school.

Yes. Daily tasks, extra practice, every game, friends, chat, calls, classrooms, the avatar and the badges are free. TONEC STUDY Premium ($19.99 a month in the US, first month half price) unlocks every curriculum question for your grade and the study tools.

Android phones and tablets, from Google Play. There’s no iPhone version yet.

TONEC STUDY is translated into 72 languages and knows the school systems of 197 countries. Everyone gets questions for their grade and subjects; questions written to a national curriculum are added country by country.

Every school year from first grade to university, in 43 subjects. Every country gets general questions and generated problems for its grades, and countries with their own curriculum questions get those too. Curriculum questions can also follow your high-school program, or your university program and year – Bachelor’s, Master’s or doctorate.

They’re written to help you learn and checked against the curriculum, but a mistake can slip through. If you think a question is wrong, tap the flag on it and we’ll look at it. TONEC STUDY doesn’t replace school, teachers or your textbook.

Your grade in a subject comes from your longest run of right answers in a row – a wrong answer starts the run again. 0–10 is a 1, 11–20 a 2, 21–30 a 3, 31–40 a 4 and 41–50 a 5. Grades are part of Premium.

Your streak counts the days in a row you open TONEC STUDY. A streak freeze costs 5 IQ in the shop and keeps your streak alive on a day you miss. You can hold up to 3.

IQ is TONEC STUDY’s currency. Every right answer earns IQ, and every item your avatar wears adds a little more. Games earn IQ too, and after a game you can double it by watching a short ad (Premium doubles it without ads). IQ packs are optional.

Every curriculum question for your grade, “Learn from your book” (quizzes from photos of your lessons), test prep, half-year and end-of-year revision, practising your mistakes, statistics and grades, a weekly report for parents (grades 1 to 9), and double game IQ without ads.

$19.99 a month in the US, and the first month is half price. In other countries Google Play shows the local price, with taxes, before you pay.

In Google Play: Payments & subscriptions → Subscriptions → TONEC STUDY → Cancel. Premium stays on until the end of the month you paid for.

Not on their own: for a child under 14, a parent confirms by email before anything can be bought. Every purchase goes through Google Play.

A Premium feature: you photograph pages of your school book and AI writes a practice quiz from them. The photos are used only to make the quiz and aren’t kept. You can scan up to 10 times a day and 120 times a month.

It’s built for them. Under-18s and adults are kept apart, chats block links, phone numbers and email addresses, swear words are masked, calls are never recorded, and parents confirm before purchases and social features. Everything about safety.

Only friends they accepted – and never adults: under-18s can only find, add, chat with and call other under-18s. Under 16, friends, chat and calls stay off until a parent says yes. Anyone can block or report another student.

Only if a student chooses: after a game they can watch a short ad to double the IQ. The ads are child-safe and never personalised. Premium has no ads.

Only what the app needs: an account, a profile with an age group (not a birthday), your progress, and what you share with friends. No analytics or tracking tools. Read the privacy policy.

In the app: Settings → Account → Delete my account. Without the app: see how to delete your account.
