The clearest difference is monetization model: Planetarium VR at free with in-app purchases against MAMOR's subscription. Planetarium VR also leads on update cadence (every 6 months vs every 12 months). MAMOR's advantage is iOS requirement (9.0 vs 16.0). On price, ads, in-app purchases and device support there is nothing between them.
