# My Physics Calculator lite vs Physics AI

The clearest difference is monetization model: My Physics Calculator lite at free with in-app purchases against Physics AI's subscription. My Physics Calculator lite also leads on rating (4.8 vs 4.5). Physics AI's advantage is update cadence (fortnightly vs every 6 months) and review sentiment (25% vs 0%). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. My Physics Calculator lite sells 1 one-off in-app purchase and Physics AI sells 2 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.

My Physics Calculator lite holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Physics AI has 288 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 0% of My Physics Calculator lite's written reviews are positive against 25% of Physics AI's, so the app with the better star average is not the one people write more warmly about.

My Physics Calculator lite ships an update every 6 months, Physics AI fortnightly. The most recent releases landed on August 15, 2026 and September 26, 2026 respectively.
