# My Physics Calculator vs Capacitor Calculator

The clearest difference is rating: My Physics Calculator at 4.3 against Capacitor Calculator's 3.8. My Physics Calculator also leads on ratings volume (44 vs 4) and update cadence (every 12 months vs every 29 months). On price, ads, in-app purchases and monetization model there is nothing between them.

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

My Physics Calculator holds the better App Store score, 4.3 against 3.8. That said, the two scores are not equally well evidenced: My Physics Calculator has 44 ratings behind it against 4, so its average is the more settled of the two.

My Physics Calculator ships an update every 12 months, Capacitor Calculator every 29 months. The most recent releases landed on November 4, 2026 and November 2, 2026 respectively.
