Verdict
The clearest difference is rating: Aosu at 3.7 against DDLock's 2.8. Aosu also leads on review sentiment (57% vs 20%) and update cadence (every 4 days vs every 4 months). DDLock's advantage is in-app purchases (none vs 10) and iOS requirement (13.0 vs 15.1). On price, ads and device support there is nothing between them.
