Verdict
The clearest difference is rating: Sub at 4.4 against SmartThermo2's 2.4. Sub also leads on ratings volume (778 vs 8) and update cadence (every 5 weeks vs every 4 months). SmartThermo2's advantage is review sentiment (33% vs 15%) and monetization model (free vs ad-supported). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Sub holds the better App Store score, 4.4 against 2.4. That said, the two scores are not equally well evidenced: Sub has 778 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 33% of SmartThermo2's written reviews are positive against 15% of Sub's, so the app with the better star average is not the one people write more warmly about.
SmartThermo2 ships an update every 4 months, Sub every 5 weeks. The most recent releases landed on September 10, 2026 and September 20, 2026 respectively.
