Math & logic challenges and 1‑v‑1 duels.
How do I answer questions with math symbols?
On typed-answer questions a symbol toolbar appears above the answer box — tap
to insert symbols like π, √, or powers. You can also type the plain form
(e.g. x^7 for x⁷, pi for π); both are accepted.
How do duels work?
In the Arena, enter another player's email to challenge them to a 1‑v‑1 on a
chosen category. Both players answer the same question; the fastest correct
answer wins. You'll get a notification when it's your turn or the duel ends.
How do I turn notifications on or off?
Notifications are optional. You can enable or disable them any time in your
device Settings → Notifications → Equation X.
How do I reset my password?
On the login screen, tap “Forgot password?” and follow the emailed link.
How do I delete my account?
Go to Profile → Delete account. This permanently removes your
profile, stats, and history. If you can't access the app, email
contact@khenitech.com and we'll
delete your data within 30 days.
