Verdict
The clearest difference is in-app purchases: solarFLUX at none against Swift Warning's 4. solarFLUX also leads on ads (none vs shown) and iOS requirement (15.1 vs 17.0). Swift Warning's advantage is update cadence (every 2 days vs fortnightly). On price and device support there is nothing between them.
