# PLC AI vs Embedded Systems+

The clearest difference is rating: Embedded Systems+ at 5.0 against PLC AI's 4.5. PLC AI's advantage is ratings volume (75 vs 2) and iOS requirement (15.0 vs 17.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. PLC AI sells 16 in-app purchases, starting at $4.99 per 7 days and Embedded Systems+ sells 6 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Embedded Systems+ holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: PLC AI has 75 ratings behind it against 2, so its average is the more settled of the two.

PLC AI ships an update every 3 weeks, Embedded Systems+ every 5 weeks. The most recent releases landed on October 16, 2026 and October 4, 2026 respectively.
