The Teaching Textbooks Pre-Algebra app makes your TT course even better! Not only will your student enjoy math while learning independently, but, with the app, that learning can also take place on the go. Even when offline! Specifically, the app can be used offline for up to 6 lessons at a time. That makes it perfect for homeschool parents who need their kids to stay productive while the family is out and about during the day. The app’s other features include… • 139 audiovisual lectures that teach every core concept in the standard 8th grade curriculum • thousands of problems that give students all the practice they need to master each concept • automated grading and instant feedback for every single problem • step-by-step audiovisual explanations to every single problem so students can see exactly what they did wrong when mistakes are made (This makes the program feel as if a tutor is at the student’s side!) • parental controls that let you track your student’s progress • the digitized version of the printed Teaching Textbooks Pre-Algebra textbook (with a search feature and a hyper-linked index) • no advertising or in-app purchase offers • Internet connectivity is required, but you can remain offline for up to 6 lessons.

Verdict
The clearest difference is rating: Master Books at 4.9 against TT Pre's 3.2. Master Books also leads on review sentiment (71% vs 42%) and ratings volume (933 vs 141). TT Pre's advantage is device support (4 vs 1) and iOS requirement (12.0 vs 18.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Master Books holds the better App Store score, 4.9 against 3.2. That said, the two scores are not equally well evidenced: Master Books has 933 ratings behind it against 141, so its average is the more settled of the two. Written reviews point the same way: 71% of Master Books's written reviews are positive against 42% of TT Pre's.
Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
