# My Physics Calculator vs Operational Amplifiers Pro

The clearest difference is rating: Operational Amplifiers Pro at 5.0 against My Physics Calculator's 4.3. Operational Amplifiers Pro also leads on update cadence (every 2 months vs every 12 months). My Physics Calculator's advantage is ratings volume (44 vs 1) and price ($2.99 vs $4.99). On ads, in-app purchases, monetization model and device support there is nothing between them.

My Physics Calculator costs $2.99 and Operational Amplifiers Pro $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Operational Amplifiers Pro holds the better App Store score, 5.0 against 4.3. 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.

My Physics Calculator ships an update every 12 months, Operational Amplifiers Pro every 2 months. The most recent releases landed on October 27, 2026 and October 19, 2026 respectively.
