Aktiv Learning vs Dig a Pig Too

Aktiv Learning is an active learning platform built specifically for college-level chemistry and mathematics. Say goodbye to static content and generic multiple choice questions and hello to dynamic problems that are designed to help students learn and visualize abstract concepts in STEM. Aktiv Learning allows chemistry instructors to ask students engaging questions, such as drawing Lewis structures, and receive real-time information on what structures the class is drawing. The app features a custom-built tool that allows students and instructors to quickly and intuitively draw Lewis structures on mobile devices. Additionally, both students and instructors have access to over 250 built-in questions related to Lewis structures, resonance, molecular geometries, VSEPR, hybridization, sigma and pi bonding, and molecular polarity. Features: • Intuitive Lewis structures drawing tool built specifically for mobile devices - Use as engaging demonstration for your students to show example Lewis structures and reinforce concepts such as the octet rule, formal charge, and VSEPR. Students can take advantage of the drawing tool to visualize the relationship between Lewis structures and molecular shapes. • Create in-class or homework assignments - Perfect for clicker, recitation, or review problems. Students receive push notifications to alert and remind them of pending assignments. • Assign or practice with over 250 built-in questions related to Lewis structures, resonance, molecular geometries, VSEPR, hybridization, sigma and pi bonding, and molecular polarity. • Real-time class results - Quickly find common incorrect structures to address student misunderstanding before exams. • Isoform recognition - Aktiv’s technology recognizes correct answers independent of the drawn structure orientation. • Export student activity - Student participation and performance exported in a tap of a button. • Easy sign-up - Students and instructors can create accounts and join courses all within the app in a few steps. • School IT and device independent - Assign, work, and review from any mobile device and over any network connection.

Dig a Pig Too is the most comprehensive fetal pig anatomy study app for Columbia University biology students preparing for lab practicals. It's built specifically around the BIOL 2501 Contemporary Biology Lab curriculum at Columbia University, updated as of Spring 2026. WHAT'S INSIDE • 398 labeled structures across 25 anatomy categories • Real Exam mode: timed, station-based practicals with gross anatomy IDs and 36 histology scenarios matching the exact BIOL 2501 slide set (all 19 class slides). • Class leaderboard & achievements: compete on a friendly Game Center leaderboard (the top 10 appear right on the home screen) and earn achievements as you master IDs, traces, and fill-ins • Mastery Score: a single score weighted like the real practical (physical IDs, then traces, then fill-ins), with bonus points for practicing quizzes and acing full-length exams • Study offline: download every photo and histology slide to your device so the app works with no internet - on the subway, in lab, or on airplane mode • iCloud sync: your stats, flashcard progress, and custom decks stay in step across your iPhone, iPad, and Mac • Flashcards with spaced repetition (SM-2) and custom decks for targeted review • Circulatory system organized into browsable sections (heart, coronary, great vessels, thoracic, abdominal, pelvic & hindlimb, fetal) so you can find any vessel fast • Swipe left and right through every structure in the atlas, even across categories • Circulatory trace practice: follow waste and hormones step by step through every vessel - now including GI waste, plus short "Building Blocks" chunks, all in the exact flow-chart format the practical is graded on, with multiple-choice or write-in cards and step-by-step images • Quiz modes: multiple choice, write-answer, and full Real Exam simulation, with category filtering and Easy / Medium / Hard difficulty • Fill-in-the-blank: 112 questions with a Smart Review mode that surfaces your weak and overdue questions first and graduates each one from multiple choice to write-in as you master it - filterable by topic, with MCAT-relevant concepts flagged • Reference diagrams for the arterial, venous, and digestive systems, plus anatomical planes, epithelial types, a labeled transverse abdominal section, and duct pathways • Progress stats so you can see what you've mastered and what needs work • Search across every structure and its aliases - now also searching the detail notes (function, histology, connections, common confusions) and fill-in questions, built right into the home screen • Community-contributed dissection and histology photos CATEGORIES COVERED Anatomical planes & directional terms · External features · Buccal (oral) cavity · Upper thoracic & peritoneal cavities · Digestive · Respiratory · Circulatory · Urinary · Male & female reproductive · Fetal structures · Adult maternal pig · Cow eye dissection · Epithelial types · Histology slides (blood, vessels, respiratory, GI, liver, pancreas, kidney, reproductive) · Microscope components · And more! STUDY SMARTER High-yield structures are flagged so you know what to prioritize, and MCAT-relevant concepts are tagged for premeds. Trace questions walk you through every organ and vessel along the path, which is perfect for the most tested and most long-winded section of any lab practical. Plus a friendly class leaderboard turn studying into a shared game - a nudge to keep going, and a way to show what you know! LIGHTWEIGHT BY DESIGN The app installs tiny; photos stream on demand, so a fresh install is just a few MB instead of the hundreds of MB that apps bundling images locally require. Prefer to study without a connection? Turn on offline mode to download the full photo library (about 300 MB) to your device. Otherwise, a Wi-Fi or cellular connection loads photos as you browse. Built by a student, for students. Free forever.
