# My Physics Calculator vs Matrix Determinant Calculator

The clearest difference is rating: My Physics Calculator at 4.3 against Matrix Determinant Calculator's 1.0. My Physics Calculator also leads on in-app purchases (none vs 1) and ratings volume (44 vs 1). Matrix Determinant Calculator's advantage is price ($0.29 vs $2.99) and chart position (#189 vs unranked). On review sentiment, ads and device support there is nothing between them.

My Physics Calculator costs $2.99 and Matrix Determinant Calculator $0.29 up front. Matrix Determinant Calculator sells 1 one-off in-app purchase. My Physics Calculator asks for nothing beyond the download.

My Physics Calculator holds the better App Store score, 4.3 against 1.0. That said, the two scores are not equally well evidenced: My Physics Calculator has 44 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 0% and 0% positive.

My Physics Calculator ships an update every 12 months, Matrix Determinant Calculator every 34 months. The most recent releases landed on August 3, 2026 and August 10, 2026 respectively.
