Verdict
The clearest difference is in-app purchases: UP DL4U at none against Matrix Operations's 1. UP DL4U also leads on ads (none vs shown) and iOS requirement (11.0 vs 15.5). Matrix Operations's advantage is update cadence (every 10 days vs every 7 months). On price and device support there is nothing between them.
