Verdict

The call

The clearest difference is rating: Warden at 5.0 against StackLock's 4.5. Warden also leads on monetization model (free vs free with in-app purchases) and device support (4 vs 2). StackLock's advantage is update cadence (every 2 days vs every 6 weeks) and ratings volume (74 vs 4). On price, ads, in-app purchases and iOS requirement there is nothing between them.
