Biology 3D is an learning tool that aims to make learning Biology in universities more captivating. It is under development by two students of Florida Institute of Technology as their Computer Science Senior Project. In its current form, it is for testing by students of Biological discovery 2 at Florida Tech. The app uses 3D models and a unique interface to interact with them. Interaction includes zooming in and out, rotating, adding and removing layers, and moving the object around.
Codon One

- Interactive learning modules
- Quick quizzes for comprehension
- Clear diagrams and plain language
- Molecule reference guide
- Sequence analysis tools
- Genetic code exploration

Codon One helps you learn biology step by step, with short lessons, quick quizzes, flashcards, and a searchable glossary. Build a solid foundation in molecular biology, genetics, evolution, cell biology, development, and the history of science. Each section breaks complex ideas into clear explanations, diagrams, and focused checks for understanding. Core course (Modules) Module 1: Chemistry of Life – atoms & elements, bonds, water, pH, biomolecules Module 2: Genetics – chromosomes, replication, transcription, translation, regulation Module 3: Evolution – history of life, phylogeny, selection, drift, speciation, molecular evolution Module 4: History of Science – ideas, methods, and experiments that shaped modern biology Module 5: Cell Biology – membranes & transport, organelles & energy, cytoskeleton, signaling, cell division Module 6: Development – fertilization & body plans, differentiation, pattern formation & morphogenesis, growth & repair, evo-devo Additional topics are planned for future updates, including Animal Physiology, Microbiology & Immunology, Plant Biology, and more. Glossary & Flashcards Look up the essentials in one place - key terms from every module, plus the 20 amino acids and the nucleobases. Turn any topic into a flashcard deck and review with smart, spaced practice that focuses on the cards you find hardest. Quiz & Progress Practice across biochemistry, genetics, evolution, cell biology, development, and science history in a dedicated quiz area. Track improvement with success rates and per-topic stats, and let the app resurface your weak questions for targeted review. Keep a daily streak going to build a steady habit. Got a good question? Submit it directly from the app. Built-in Tools Sequence Operator: paste DNA, reverse or complement it, transcribe to RNA, translate in all six reading frames, and view length, GC content, and melting temperature. Codon Picker: explore the genetic code, see which codons map to each amino acid or stop signal, and tweak bases to see the effect. Triplet Encoder: write a message in amino-acid single-letter code and encode it as a DNA triplet sequence, then decode it by translation. Found a bug or have suggestions?

Verdict
The clearest difference is rating: Biology3D at 5.0 against Codon One's 4.5. Biology3D also leads on in-app purchases (none vs 7) and update cadence (weekly vs every 3 weeks). Codon One's advantage is ratings volume (25 vs 1). On price, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Codon One sells 7 one-off in-app purchases. Biology3D asks for nothing beyond the download.
Biology3D holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Codon One has 25 ratings behind it against 1, so its average is the more settled of the two.
Biology3D ships an update weekly, Codon One every 3 weeks. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
