Codon: Learn Biology
Molecules to ecosystems — and the numbers textbooks get wrong.

Codon covers what an introductory sequence and the first two years of a degree teach: molecules and cells first, then inheritance and molecular biology, then evolution, diversity and ecology, then whole organisms and physiology.
The course teaches mechanisms rather than vocabulary. Where a textbook says respiration yields 38 ATP, this one gives the real figure of roughly 30 to 32 and explains why the number moved. Where the field is unsettled — the origin of eukaryotes, the tempo of speciation — the lesson gives the competing accounts and who holds them.
- 60 researcher profiles, from Mendel and Darwin to McClintock and Doudna.
- 18 landmark experiments reconstructed: Meselson and Stahl, Hershey and Chase, Luria and Delbrück.

What you get
100 lessons, four years
A full degree-shaped sequence, 15 to 25 minutes a lesson, in the order the subject is actually taught.
On-device narration
Listen instead of read. Narration uses the system speech synthesizer, so no audio ever leaves the phone.
Cross-linked glossary
Hundreds of terms, each linked back to the lessons that use it and forward to the ones that build on it.
Case files
18 landmark studies, experiments or episodes reconstructed in full, each listing the record it rests on.
Spaced repetition
The scheduler brings back the terms you keep forgetting, on the interval that makes them stick.
Daily widgets
Three Home Screen widgets — a quote, a term and a figure — each rotating daily.

FAQ
How much is free?
The first ten lessons. One purchase of $9.99 unlocks the remaining ninety and everything else, permanently, with Family Sharing enabled.
Does it need an internet connection?
No. The app makes no network connections of any kind. Every lesson, profile, glossary entry, quiz and case study is bundled in the download, which is why the download is large.
Is this accredited? Do I get credit?
No. It is a self-study course written to the level of a university survey sequence. It carries no accreditation and grants no credit.
Where do the numbers come from?
Every effect size, sample size and date in a lesson is stated so it can be checked. Case files list the specific record they rest on. Where a familiar textbook figure is wrong, the lesson gives the real one and explains why it moved.
How do I move my progress to a new phone?
Progress, bookmarks and notes are stored on-device and are included in an encrypted iPhone or iCloud device backup. Restoring that backup onto the new phone brings them across. There is no account-based sync.
