Verdict
The clearest difference is in-app purchases: Mosaicizer at none against Lockpup's 3. Mosaicizer also leads on iOS requirement (15.6 vs 17.0). Lockpup's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 3 months). On price and device support there is nothing between them.
