Verdict
The clearest difference is in-app purchases: DataLock Managed at none against Strontium's 2. DataLock Managed also leads on update cadence (every 2 months vs every 5 months). Strontium's advantage is iOS requirement (8.0 vs 11.0). On price, ads and device support there is nothing between them.
