Track the latest storms and other natural events worldwide with Earth++. The latest weather, earthquakes, climate changes, and marine conditions are available. Information is courtesy of a variety of open sources, as indicated in the attribution label. There is an auto-renewing subscription option within the app to remove ads, track tropical cyclones, typhoons, hurricanes and other global weather hazards, and comprehensive ocean conditions forecasts for the Atlantic and Pacific oceans. Development of global storms is funded in part by ads, which can be removed by selecting the monthly auto-renewing subscription option "Premium upgrade" from the app's settings menu. Upgrading to premium also provides access to other premium content and features. The subscription price of 0.99 USD (in your local currency) will be charged to your iTunes account at confirmation of purchase and, for each renewal, within 24 hours prior to the end of the current month. You can cancel the subscription at any time through your iTunes account settings, but you must do so at least 24 hours before the end of the current month to avoid being charged, and ads will show again at the start of the subsequent month.

Verdict
The clearest difference is rating: Earth++ at 4.4 against Solar System's 3.7. Earth++ also leads on ratings volume (285 vs 3). Solar System's advantage is in-app purchases (none vs 5) and ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
