ViviCell
-
A free, non-commercial study companion for hematology, coagulation, blood-cell morphology, related pathology, and MLS exam review.
What ViviCell is
ViviCell is an independent educational app built for Medical Laboratory Science students and laboratory professionals reviewing hematology and coagulation. It combines structured lessons, spaced-repetition review, quizzes, case studies, morphology references, cell and pathology atlases, and image-based cell-identification practice in one offline app.
The goal is practical review: learn a topic, enroll its flashcards, revisit material before it fades, train your eye with microscopy images, and use progress insights to decide what deserves another pass.
How the app is organized
Five sections cover the full study loop, from first exposure through practice and reference.
How the app is organized — details
Learn
Study hematology and coagulation modules with objectives, concise explanations, diagrams, flashcards, quizzes, and clinical case studies.
Review
Enroll flashcards from any module and grade each review as Again, Hard, Good, or Easy. ViviCell schedules future reviews from your recall difficulty so weaker material comes back sooner.
Practice
Identify cells and cellular aberrations from real photomicrographs. Practice sessions can focus on specific categories, adjust difficulty, and feed missed or graded images back into Review.
Atlas
Browse blood cells by class, lineage, and category, plus cellular-aberration findings and pathology conditions. Atlas entries emphasize recognition features, common confusions, representative images, and source attribution.
Search
Search across lessons, flashcards, quiz explanations, case studies, morphology cards, cell categories, cellular-aberration findings, and pathology conditions from one place.

Which heavy metal exposure classically produces basophilic stippling?
Lead poisoning. When you see basophilic stippling in a child with anemia and abdominal pain, order a blood lead level.
