Verdict

The call

The clearest difference is in-app purchases: Prikan at none against NyanLock's 2. Prikan also leads on iOS requirement (17.6 vs 26.0). NyanLock's advantage is ads (none vs shown) and update cadence (every 4 days vs every 3 weeks). On price and device support there is nothing between them.
