Platelet WBC Counter
Laboratory Medical Tool
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
Fast platelet and WBC counting for the lab. One-tap counts, live totals, and results you can share or export.
Platelet & WBC Counter helps lab staff, medical and veterinary students, and clinicians practice and document manual platelet estimates and white blood cell differentials on the go—without paper tallies.
WHY USE IT
• Platelet counting: tally across 10 smear fields, apply your microscope correction factor, and get totals and platelets/µL aligned with common lab practice.
• WBC differential: count myelocyte through basophil with a running total, then see percentages and absolute counts (µL) from the leukocyte total you enter.
• Reports: review a clear leukogram-style summary and generate professional PDFs with patient/context fields when you need documentation.
• Built for real workflows: dark and light themes, optional sound feedback, 10 languages, and settings you can trust in the lab.
IDEAL FOR
• Medical and veterinary students
• Laboratory technicians and trainees
• Hematology and clinical pathology learners
• Anyone teaching or reviewing peripheral blood smear skills
NOTE: The app supports educational and documentation-style counting; always follow your institution’s protocols and equipment manuals for clinical use.
