Verdict
The clearest difference is rating: ViGuide at 4.5 against ComfoControl's 3.8. ViGuide also leads on ratings volume (209 vs 6) and update cadence (every 5 weeks vs every 4 months). ComfoControl's advantage is review sentiment (60% vs 41%) and iOS requirement (13.0 vs 16.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
ViGuide holds the better App Store score, 4.5 against 3.8. That said, the two scores are not equally well evidenced: ViGuide has 209 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 41% of ViGuide'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, ViGuide every 5 weeks. Both last shipped on November 6, 2026.
