Verdict
The clearest difference is rating: HD at 5.0 against Step In Time's 4.3. HD also leads on in-app purchases (none vs 3) and iOS requirement (13.0 vs 17.2). Step In Time's advantage is update cadence (every 2 months vs every 10 months) and ratings volume (20 vs 3). On price, ads and device support there is nothing between them.
