# Plusfinity AI vs Physics AI

The clearest difference is review sentiment: Plusfinity AI at 78% against Physics AI's 25%. Plusfinity AI also leads on monetization model (free with in-app purchases vs subscription) and ads (none vs shown). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Plusfinity AI sells 8 in-app purchases, starting at $8.99 per 7 days 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.

Plusfinity AI holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Plusfinity AI has 2.1K ratings behind it against 287, so its average is the more settled of the two. Written reviews point the same way: 78% of Plusfinity AI's written reviews are positive against 25% of Physics AI's.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on October 2, 2026 and September 30, 2026 respectively.
