About Codon
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.
Lessons explain mechanisms. Where a textbook says respiration yields 38 ATP, Codon gives the current figure of about 30 to 32 and explains why the number moved. Where the field is unsettled, as with the origin of eukaryotes or the tempo of speciation, the lesson gives the competing accounts and who holds them.
- 82 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 degree-shaped sequence of 15-to-25-minute lessons, in the order a university teaches the subject.
On-device narration
The iOS speech synthesizer reads lessons aloud on the device, so no audio 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
Terms you forget come back for review the next day, and the gaps between reviews grow as you keep recalling them.
Daily widgets

Common questions
How much is free?
The first ten lessons. One purchase of $9.99 unlocks the remaining ninety and everything else, permanently. An App Store purchase also covers the people in your Family Sharing group. Google Play has no family sharing for a one-time in-app purchase, so a Play purchase unlocks the course for the account that bought it.
Does it need an internet connection?
The course content itself works offline: every lesson, profile, glossary entry, quiz and case study is bundled in the download. On iPhone and iPad, App Store product loading, buying or restoring the one-time unlock requires a network connection. The Android build holds no internet permission, so the Google Play Store app on your phone carries the purchase and the restore.
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. On iPhone and iPad, an encrypted device or iCloud backup may include them according to your Apple backup settings. On Android, the app's data can reach a new device through Android's cloud backup and device-to-device transfer, according to your Google backup settings. There is no account-based sync, so confirm that a current backup exists before moving devices. If the new phone still shows the paywall, tap Restore Purchases in the app's settings: on iPhone and iPad that asks the App Store to re-check the unlock, and on Android it asks Google Play.
