IRAKU is a visual education app for genetics, DNA, and evolution. Learn by seeing and playing. The 17th title in the long-running "RAKU" series that started with SUUGAKU (math), BUTURAKU (physics), and continues through DENRAKU (electricity), HARAKU (waves), NETURAKU (heat), SEIRAKU (astronomy), KORAKU (optics), RYORAKU (quantum), RYURAKU (fluids), KAKURAKU (probability), KIKARAKU (geometry), KAGAKU (chemistry), KINRAKU (microbiology), NOURAKU (neuroscience), KIKARAKU (mechanics), and CHIRAKU (geology). This time the theme is genetics, DNA, and evolution. Nine topics covering high school through introductory college biology, packaged as beautifully animated simulations. [Nine simulators] - DNA Double Helix Viewer Pseudo-3D rotating double helix. Adjust base-pair count (6 to 40) and rotation speed; enter your own sequence, generate a random one, or hit Mutate to flip a single base. Tap any base to see position, hydrogen-bond count, and surrounding context. - Central Dogma A five-stage animation: DNA strands unwind, mRNA is transcribed from the template strand, exported to the cytoplasm, translated codon-by-codon at the ribosome, and a polypeptide chain emerges. Play, pause, reset, and adjust speed. - Punnett Square (Mendelian Cross) Pick parental genotypes (AA / Aa / aa) and immediately see the offspring genotype distribution and dominant:recessive phenotype ratio. Switch to dihybrid mode to experience independent assortment (9:3:3:1). - Codon Translator Type a DNA sequence; the app transcribes mRNA and translates to the 20 amino acids. Switch between three reading frames, and consult the built-in 64-codon table. - Mutation & Evolution Add mutation rate and selection pressure (e.g. recessive lethality) to a population, then step generations to watch genotype frequencies shift on both an individual grid and a line chart. Shrink the population to see genetic drift kick in. - Hardy-Weinberg Equilibrium The null model of population genetics: pยฒ + 2pq + qยฒ = 1. Slide allele frequency p and each genotype's fitness, then advance generations and watch the bar chart and trajectory drift away from equilibrium. - Phylogenetic Tree Builder Enter multiple sequences; the app computes Hamming distances, builds a distance matrix, and clusters via UPGMA to draw a tree. Human, chimpanzee, mouse, and chicken sequences are preloaded. - CRISPR Lab Design a 20-nt guide RNA and cut with Cas9. The app detects PAM sites (NGG) on both strands, then resolves the cut via NHEJ (indels) or HDR (donor-template replacement). See the edited sequence vs. the original. - Karyotype Viewer Human's 23 chromosome pairs arranged in a karyotype. Tap to switch among normal (46,XX / 46,XY), trisomy 21 / 18 / 13, Turner syndrome (45,X), and Klinefelter syndrome (47,XXY). [Features] - Info sheet with the underlying equations or principles in every simulator - Real-time visualizations of central dogma, Punnett squares, Hardy-Weinberg, UPGMA, and more - Japanese and English supported - Dark and Light modes - Intuitive, polished UI [Who it's for] - High-school biology and college genetics students - Anyone who wants to internalize how DNA, genes, and evolution actually work - Teachers looking for a classroom demo or a tablet-based supplement - Anyone who reads "genome" or "genetic testing" in the news and wants the real picture

MLS Exam Prep

Pass the medical laboratory scientist board exam with confidence. MLS Exam Prep gives you 1,518 board-style practice questions โ€” and every single one comes with a detailed explanation you can actually learn from. Not a bare answer key: each question explains why the correct answer is right AND why each wrong option is wrong, so you build reasoning instead of memorizing letters. TRAIN YOUR EYE The board exam shows you specimens, charts, and lab visuals and expects instant recognition. That's why 200 questions are built on real microscopy images โ€” blood-cell morphology (sickle cells, spherocytes, Auer rods, inclusions and more), Gram and acid-fast stains, parasite ova and malaria smears, and urine crystals and casts. You practice the visual recognition the real exam tests, the way it actually tests it. WHAT'S INSIDE - 1,518 board-style practice questions across all 7 exam domains, balanced to the real exam blueprint. - A detailed explanation on every question, including the rationale for each wrong choice. - Smart practice modes: Smart Review uses spaced repetition to resurface what you're about to forget, plus a Weak-Areas drill, Shuffle, and the full timed mock. - 3-stage learning on every topic: Skim the key points, drill swipeable flashcards, then test yourself with a quiz. All 34 topics include all three stages. - 37 concise study notes and 638 flashcards covering every topic. - A full-length timed mock exam: 100 questions in 150 minutes, weighted to mirror the real domain blueprint and real test pacing. - A missed-question review notebook so you can attack your weak spots. - A home dashboard with a readiness gauge and a "today's plan", plus an exam-date study planner. - Works 100% offline โ€” study on the train, on break, or anywhere in the lab with no signal. - Light and dark mode. COVERS ALL 7 BOARD DOMAINS Blood Banking, Clinical Chemistry, Hematology, Microbiology, Immunology, Urinalysis & Body Fluids, and Laboratory Operations. UPDATED FOR 2026 New questions are added regularly at no extra cost โ€” so your prep stays current for 2026 and keeps growing, instead of a one-time static dump. GREAT FOR Medical laboratory scientist (MLS) and clinical laboratory scientist (CLS) candidates, MLT students stepping up to MLS, and clinical lab professionals refreshing before certification or recertification. LIFETIME UNLOCK โ€” ONE PAYMENT Unlock the complete 1,518-question bank, every topic, the full timed mock exam, and the missed-question review notebook with a single Premium purchase. - Pay once โ€” yours forever.

Verdict

The call

The clearest difference is in-app purchases: IRAKU at none against MLS Exam Prep's 1. IRAKU also leads on device support (3 vs 1) and iOS requirement (13.0 vs 16.4). MLS Exam Prep's advantage is ads (none vs shown). On price there is nothing between them.
