Verdict
The clearest difference is review sentiment: ComfoControl at 60% against ENGIE Smart App's 21%. ComfoControl also leads on iOS requirement (13.0 vs 15.0). ENGIE Smart App's advantage is rating (4.2 vs 3.8) and update cadence (monthly vs every 4 months). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
ENGIE Smart App holds the better App Store score, 4.2 against 3.8. That said, the two scores are not equally well evidenced: ENGIE Smart App has 46 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 60% of ComfoControl's written reviews are positive against 21% of ENGIE Smart App's, so the app with the better star average is not the one people write more warmly about.
ComfoControl ships an update every 4 months, ENGIE Smart App monthly. Both last shipped on October 24, 2026.
