# Simurelay vs PLC AI

The clearest difference is rating: PLC AI at 4.5 against Simurelay's 3.9. PLC AI also leads on update cadence (every 3 weeks vs every 7 months) and ratings volume (84 vs 18). Simurelay's advantage is review sentiment (52% vs 29%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Simurelay sells 3 one-off in-app purchases and PLC AI sells 16 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

PLC AI holds the better App Store score, 4.5 against 3.9. Both are backed by a comparable volume of ratings — 18 and 84 respectively. Written reviews complicate that: 52% of Simurelay's written reviews are positive against 29% of PLC AI's, so the app with the better star average is not the one people write more warmly about.

Simurelay ships an update every 7 months, PLC AI every 3 weeks. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
