# Transistors Handbook vs Linear Algebra Pro

The clearest difference is review sentiment: Linear Algebra Pro at 100% against Transistors Handbook's 27%. Linear Algebra Pro also leads on rating (5.0 vs 4.0). Transistors Handbook's advantage is update cadence (fortnightly vs every 4 months) and ratings volume (22 vs 1). On ads, in-app purchases, monetization model and device support there is nothing between them.

Transistors Handbook costs $3.99 and Linear Algebra Pro $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Linear Algebra Pro holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: Transistors Handbook has 22 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 27% of Transistors Handbook's written reviews are positive against 100% of Linear Algebra Pro's.

Transistors Handbook ships an update fortnightly, Linear Algebra Pro every 4 months. The most recent releases landed on October 6, 2026 and October 19, 2026 respectively.
