About MathTre

MathTre is a simple math workout for addition, subtraction, multiplication, division, and running sums. Your times are recorded so you can chase a new personal best.

  • 5 calculation modes — Addition, subtraction, multiplication, division, and Sums, where you add up a series of numbers.
  • 1 to 5 digits — Choose the digits for each number, the number of questions, and how many numbers to add in Sums.
  • Timing and records — Your clear time and time per question are recorded, and "New Record!!" appears when you beat your best.
  • Theme and sound — Switch between system, light, and dark themes, and turn sound on or off.

Every mode and feature is free to use (with ads).

FAQ:

  • How do I remove ads? — Tap the gear button on the home screen to open Setting, then tap "Remove Ads" under "Paid version". You can also open the purchase screen from "Remove Ads" at the bottom of the home screen or on the results screen. A single one-time purchase hides all banner and full-screen ads.
  • Is this a subscription? — No. It's a one-time purchase, so once you buy it you can use MathTre ad-free for good with no further payments.
  • How do I get my purchase back on a new device or after reinstalling? — Sign in with the same Apple Account you purchased with, then tap "Restore Purchases" at the bottom of the Setting screen or on the Remove Ads purchase screen.
  • Can I go ad-free without buying? — Watch an ad to the end from "Watch an ad for 24 hours ad-free" on the purchase screen, or "24h Ad-Free" on the results screen, and ads are hidden for 24 hours. The remaining time is shown while it's active, and it can't be extended until it runs out.
