Verdict
The clearest difference is in-app purchases: SwapOne at none against Mobile Master's 3. SwapOne also leads on ads (none vs shown) and iOS requirement (13.0 vs 17.6). Mobile Master's advantage is update cadence (every 6 days vs every 4 weeks). On price and device support there is nothing between them.
