Verdict
The clearest difference is in-app purchases: SumDU at none against Habit Tracker's 2. SumDU also leads on device support (3 vs 1) and iOS requirement (12.1 vs 18.0). Habit Tracker's advantage is update cadence (every 4 days vs every 8 months). On price and ads there is nothing between them.
