Dig a Pig Too vs Parallel

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.

Who lived at the same time as Mozart, Van Gogh, or Napoleon? Parallel lays out several timelines at once, and the connections that usually stay hidden appear at a glance. It's your tool for assembling history around what interests you. Ten curated collections come built in, from earth history and the arts to sciences, rulers, empires, buildings, and the events that shaped history. They make it easy to start and give you a taste of what Parallel can do. The rest is yours to shape. For the curious, for the classroom, for everyone who loves history. WHAT YOU CAN DO • Swipe and zoom through the millennia, from antiquity to today. • Line up exactly the collections that fascinate you. • Highlight a person and see their contemporaries at a glance, while everything else fades into the background. • Open any entry for a clear, concise biography or summary, with a link to Wikipedia. • Bring dates and the Wikipedia link straight from Wikidata into your own entry. • Follow a single thread through time, filtered by topic, place, era, and more. • Create your own collections and fill them with what matters to you. • Zoom out from a single year all the way to 13.8 billion years. Every built-in entry is carefully researched, historically grounded, and fact-checked. Try it for free Ancient Rome is included as a ready-made sample collection, no Pro needed. In a few seconds you see how a collection comes together, and it stays with you afterwards. Buy once, no subscription. You buy Parallel just once. The Pro upgrade lifts every limit: unlimited collections and entries, creating and filling your own collections from a spreadsheet or from copied text, your own copies of the built-in collections, and exporting the whole timeline as a PDF. No hidden costs. If you want to go deeper into specific topics, optional premium collections are available. Private and offline Your entries stay on your iPhone. No account, no sign-up, no tracking. The app works offline. Only the Wikidata look-up needs an internet connection. History belongs to everyone, but your data belongs to you.
