# HVAC/R AI Pro vs Essimu Plus

The clearest difference is iOS requirement: Essimu Plus at 13.0 against HVAC/R AI Pro's 16.4. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. HVAC/R AI Pro sells 2 in-app purchases, starting at $9.99 per month and Essimu Plus sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
