Gene Tutor is an App designed as a Study Aid for students taking a standard College level course in Genetics. Although it was specifically designed for students taking “Molecular and Mendelian Genetics” at Barnard College, Columbia, the material should be relevant to any similar course or advanced Introductory Biology course anywhere. It covers topics such as Mendelian Inheritance, Pedigree Analysis and Sex Linkage in Classical Genetics and DNA structure, Gene Expression and Gene Regulation in Molecular Genetics. The App contains: • Sample Questions for every topic (mainly Multiple Choice format). • Extensive Study Material in the form of web pages specifically designed for a mobile device and containing many figures and embedded videos • A Glossary covering the most commonly encountered terms • The ability to Flag questions for easy retrieval • A Shuffle option to get random questions from any topic or from the whole set overall • Three levels of questions with the option of limiting which level you get questions from I hope that this App proves to be a useful tool for students. Please feel free to let me know if you find any problems or if you think of any ways in which I could improve this for students in future classes.

Verdict

The call

The clearest difference is in-app purchases: Gene Tutor at none against Crash Course's 13. Gene Tutor also leads on iOS requirement (9.3 vs 15.6). Crash Course's advantage is ratings volume (1.6K vs 1) and review sentiment (76% vs 67%). On price, rating, update cadence and ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Gene Tutor holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Crash Course has 1.6K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 67% of Gene Tutor's written reviews are positive against 76% of Crash Course's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Gene Tutor ships an update every 6 months, Crash Course every 4 months. The most recent releases landed on October 23, 2026 and October 29, 2026 respectively.
