# EinstIA vs Physics AI Problem Solver

The clearest difference is rating: Physics AI Problem Solver at 4.2 against EinstIA's 1.0. Physics AI Problem Solver also leads on monetization model (free with in-app purchases vs subscription) and ratings volume (6 vs 1). EinstIA's advantage is ads (none vs shown) and update cadence (every 4 days vs every 2 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. EinstIA sells 4 in-app purchases, starting at $1.99 per 7 days and Physics AI Problem Solver sells 3 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Physics AI Problem Solver holds the better App Store score, 4.2 against 1.0. That said, the two scores are not equally well evidenced: Physics AI Problem Solver has 6 ratings behind it against 1, so its average is the more settled of the two.

EinstIA ships an update every 4 days, Physics AI Problem Solver every 2 months. Both last shipped on October 24, 2026.
