Verdict
The clearest difference is price: HandyPlanet at Free against Satellite Rotation's $0.99. HandyPlanet also leads on update cadence (every 6 weeks vs every 7 months). Satellite Rotation's advantage is ads (none vs shown) and iOS requirement (11.0 vs 18.6). On in-app purchases and device support there is nothing between them.
