Verdict
The clearest difference is review sentiment: Tempur® Sleeptracker at 37% against Sub's 15%. Tempur® Sleeptracker also leads on rating (4.7 vs 4.4) and ratings volume (32K vs 778). Sub's advantage is update cadence (every 5 weeks vs every 3 months) and iOS requirement (15.5 vs 17.5). On price, ads, in-app purchases and device support there is nothing between them.
