Verdict
The clearest difference is in-app purchases: SternbergTests at none against Lorraine Helper's 1. SternbergTests also leads on iOS requirement (15.0 vs 18.6). Lorraine Helper's advantage is update cadence (every 5 days vs every 9 months). On price, ads and device support there is nothing between them.
