Verdict
The clearest difference is ads: ThermoThink at none against SolarShield Geomagnetic Alerts's shown. ThermoThink also leads on iOS requirement (12.0 vs 15.5.0). SolarShield Geomagnetic Alerts's advantage is update cadence (fortnightly vs every 2 months). On price, in-app purchases and device support there is nothing between them.
