Verdict
The clearest difference is review sentiment: Cosmos at 100% against Planetaria's 50%. Cosmos also leads on price (Free vs $4.99) and update cadence (daily vs every 5 months). Planetaria's advantage is device support (3 vs 1). On ads, in-app purchases and iOS requirement there is nothing between them.
