Mental Math: Daily Challenge

Mental Math: Daily Challenge is a clean arithmetic practice app for teenagers and adults who want short timed rounds, without an account.

Practice addition, subtraction, multiplication and division in focused sessions. Play one operation at a time or mix them together. Difficulty rises as you answer correctly, so each round stays quick and challenging.

TIMED MATH ROUNDS

Start a fast arithmetic round at any time.

Choose 30, 60 or 120 second rounds, a 20 question countdown, or no mistake mode.

Practice addition, subtraction, multiplication or division, or mix them for a harder session.

True or false and find the sign rounds add variety.

Your record for each mode stays on your device.

DAILY CHALLENGE

Play the same daily challenge as everyone else each day.

Keep a streak of consecutive days and see it on a calendar.

A daily reminder at 6 pm is on by default, and you can turn it off in the settings.

PROGRESS AND STATS

Earn experience and level up as you practice.

Earn 13 badges: a perfect round, quick answers, 3, 7 and 30 day streaks, 500 and 5,000 answers, all 12 times tables, a first duel, 20 answers without a mistake, 10 daily challenges and level 10.

See your accuracy, your record and the number of rounds for each operation. Pro adds the average response time, the score curve and the full round history.

TWO PLAYER DUEL

Challenge someone on the same phone.

The screen is split into an upper half and a lower half, one for each player, facing each other.

The first correct answer scores, and a wrong answer pauses that player for a moment.

A quick local math duel, with no online play and no account.

TIMES TABLES PRACTICE

Practice multiplication tables from 1 to 12.

Pick only the tables you want to work on, or all of them.

Use it as a multiplication speed test or a short table drill.

OFFLINE AND NO ACCOUNT

Practice modes work offline.

No account is required.

Scores, streaks, levels and badges stay on your device.
