Sugoku vs Thoth

Sugoku is a drill app for high school mathematics, shown the way it looks in a printed textbook: fractions stacked with a horizontal bar, √ with a vinculum, raised exponents, and ∫, Σ, lim rendered properly. Problems are generated on the fly, so you never run out of practice. WHAT YOU CAN PRACTICE - 235 topics covering the full Japanese high school curriculum (Math I, A, II, B, C, III): algebra and proof, quadratic functions, sets and logic, trigonometry, exponentials and logarithms, analytic geometry, differentiation and integration, sequences, statistical inference, vectors, complex plane, conic sections, limits and calculus. - Three difficulty levels, from fundamentals to university entrance exam level. - Answers are not forced to be integers: type fractions and radicals directly. The answer boxes show the shape of the answer, so you learn how results are written. - Figures label vertices, angles and side ratios; graphs plot key points (intercepts, vertex, center). - Missed problems come back immediately. Bookmarks and mistake analysis let you drill only your weak spots. KYOKUISEN (RANKING) - A daily rating match with a leaderboard grouped by school year. - One attempt per day; watch a video ad to add attempts, up to three per day. - Your nickname and rating are visible to other players. Do not enter your real name or anything you would not want public. - Offline, your own records are shown instead. SUGOKU PREMIUM (IN-APP PURCHASE) - Removes ads. - Three Kyokuisen attempts every day, no video ads needed. - Bookmarks up to 500 items (20 on the free tier). - Answer timer with time analysis, plus the Sakura skin. - One-time purchase. Restore from the settings screen. ADS - On the free tier, banner ads appear on the topic list and the result screen. - Video ads play only when you choose to add a Kyokuisen attempt. Ads never interrupt you mid-problem. PLEASE NOTE - The app interface is available in English and Japanese. Problem statements are written in Japanese; because the content is mostly mathematical notation, most problems are solvable without Japanese, but full Japanese localization of the problem text is not available yet. - Requires iOS 17.0 or later, iPhone and iPad. Study records are stored on your device. Leaderboard data is stored in Apple CloudKit. See the privacy policy for details, or contact us through the support page.
