Epicentral is a network-based educational application that displays lists and maps of earthquakes that occurred during the last day, week, or month. This version runs on iPhones, iPads, and Macs (as an iPad App) but requires iOS 26+ and macOS 26+. The data are served by the U.S. Geological Survey or the European-Mediterranean Seismological Centre (and three other seismological organizations). List updates take at most a few 10s of seconds. For each event, a summary of the event’s properties and relationship to nearby recent seismicity is presented. When using the USGS feeds, a link to the event-specific USGS earthquake information page is available. Several historical earthquake catalogs (sourced from the US Geological Survey) are included to provide context for more recent earthquakes. These catalogs can be used to put more recent activity in context.

Homework should not feel like a hostage situation. Math Tutor AI is an AI-powered math tutor, homework helper, practice coach, calculator, and learning game platform built to help students actually understand math, not just copy answers. Scan a problem, write it by hand, say it out loud, or type it in. Math Tutor AI reads the problem, explains the steps, checks your work, helps you practice, and keeps track of what you are improving over time. A Tutor That Actually Teaches Most math apps give you the final answer and call it help. Math Tutor AI is built around learning. Use different tutor modes based on what you need: Guide Me: get hints and questions that help you solve it yourself Explain It: see clear step-by-step explanations Check My Work: find exactly where your work went wrong Teach It Back: explain the idea yourself and see how well you understand it Practice Mode: build skill with targeted problems Learn Mode: review lessons and concepts before practicing Personalized To The Student Math Tutor AI adapts to the learner’s level, from early arithmetic to advanced math. It supports: Arithmetic Fractions Decimals Pre-algebra Algebra Geometry Trigonometry Statistics Calculus Physics and circuits SAT and ACT-style math practice The app tracks skill progress, weak areas, mastery, mistakes, streaks, achievements, and recommended next steps. Scan It, Write It, Say It, Type It Students can enter math in the way that feels easiest: Camera scanning Worksheet scanning Multiple-problem detection Handwriting input Voice input Typed math input Built-in calculator tools Before solving, the app shows what it recognized so mistakes from scans or handwriting can be corrected. Practice That Remembers You Math Tutor AI includes adaptive practice, skill review, mistake detection, placement-style questions, and a visual learning path. When a student gets something wrong, the app helps explain why instead of simply marking it incorrect. It can identify common issues like: Sign errors Order of operations mistakes Decimal slips Fraction mistakes Incomplete answers Weak prerequisite skills Math Games And Brain Training Practice does not have to feel like a worksheet. Math Tutor AI now includes math games, puzzles, brain games, timed challenges, skill games, and visual practice activities for learners from kids to adults. Games are connected to real math skills so practice still builds progress. Parent Tools That Show Real Progress Parents can see what their child is working on, what skills are improving, where they are struggling, and what to focus on next. Parent features include: Child profiles Progress summaries Skill mastery tracking Learning goals Assignments Reports Alerts Recommended next steps The goal is simple: help parents see whether their child is actually improving. Rewards That Mean Something Students can earn XP, streaks, badges, achievements, avatar upgrades, and unlockable customization through real learning activity. No random tapping. No fake rewards. Just progress students can feel proud of. Built For Every Age Whether your child is learning addition, stuck on fractions, preparing for algebra, reviewing geometry, or trying to survive calculus, Math Tutor AI adjusts the explanation to match the learner. Free to start. Ask questions with credits, unlock more practice, or upgrade for a fuller tutoring experience.
