BEST RUNS • Best runs are now ranked separately for Visual (no voice), Spoken (voice with the question shown) and Audio only (voice with the question hidden), so you only compete against like-for-like runs. • Spoken runs show the voice and speed you used. • Runs saved before this update are kept and labelled "Mode unknown". ### 1.0.2 — 2026-10-24 New in 1.0.2 PRACTICE MODES • Recall: after a correct answer, type the question's digits back from memory (box by box) before moving on. • Zen mode: hides the clock, stopwatch and timer bar until the run ends. MORE QUESTION OPTIONS • New presets: 2−2 positive, 2−2 negative and 2−2 mixed. For negative answers the minus is already in the answer box, so you only type the digits. • Ending digits: only get numbers that end in the digits you choose. • Subtraction style setting: Classic, Above 0, Below 0 or Mixed. • Skip button on every question. Skipped questions are listed on the results screen and don't count as solved. DIVISION AND SUBTRACTION • Division now follows Zetamac's rules: the number you divide by comes from the first range and the answer from the second. • Hard mode is explained in Settings. IN-GAME • Quit button at the top of the screen. It takes you straight back to the menu, no confirmation. • Stronger green flash when you answer correctly, with a new Green flash switch in Settings under Feedback. • Default voice speed is now 1.0. ### 1.0.1 — 2026-10-24 What's new in this version: • **Redesigned keypad:** A new iPhone-style number pad with round keys that light up and smoothly fade as you tap. • **Faster, more reliable typing:** Improved touch detection means rapid taps and overlapping fingers register reliably, even when typing at full speed. • **Improved audio playback:** The Repeat button now restarts spoken questions smoothly, even when tapped repeatedly. • **Faster spoken questions:** Questions are now read slightly faster by default, with adjustable playback speed in Settings. • **Fairer timing:** The stopwatch starts only after the entire spoken question has finished, so listening time doesn't count against your score. • **Replay tracking:** A new "Heard 2 times" indicator shows when you've replayed a question, with the information also included in your results. • **Clearer time formatting:** Longer sessions now display minutes and seconds, such as 1:23.4. • **Uninterrupted practice:** Your game continues running when you switch apps or lock your phone, rather than automatically pausing. • **General improvements:** Additional bug fixes, performance improvements and interface polish for a smoother mental maths experience. ### 1.0 — 2026-10-23 No release notes. ## Apps similar to Thetamac | App | Rating | Price | Category | | --- | --- | --- | --- | | [Grammar: Figures of Speech](https://appshunter.io/ios/app/grammar-figures-of-speech/id370144334) | 3.0 (2) | Free | Education | | [Grammar Up : 1800 Questions](https://appshunter.io/ios/app/grammar-up-1800-questions/id299024911) | 4.7 (39) | Free | Education | | [English - Parts of Speech](https://appshunter.io/ios/app/english-parts-of-speech/id368018817) | 4.6 (117) | Free | Education | | [11+ Non Verbal Reasoning](https://appshunter.io/ios/app/11-plus-non-verbal-reasoning/id614404166) | 3.8 (4) | Free | Education | | [Mathematics: Formulas & Quiz](https://appshunter.io/ios/app/mathematics-formulas-and-quiz/id1584544286) | 4.4 (11) | Free | Education | | [Zetamac Arithmetic Practice](https://appshunter.io/ios/app/zetamac-arithmetic-practice/id6737153617) | 4.7 (19) | Free | Education | ## More apps by Samuel Lee - [AlgoMe: Feed Insights](https://appshunter.io/ios/app/algome-feed-insights/id6803135557) All apps by Samuel Lee: https://appshunter.io/developer/6803135559 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
