The clearest difference is in-app purchases: SOS Remote at none against Exoplanet's 7. SOS Remote also leads on rating (5.0 vs 4.7) and review sentiment (100% vs 91%). Exoplanet's advantage is update cadence (every 2 weeks vs every 8 months) and ratings volume (956 vs 2). On price, ads and device support there is nothing between them.

Both are free to download. Exoplanet sells 7 one-off in-app purchases. SOS Remote asks for nothing beyond the download.

SOS Remote holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Exoplanet has 956 ratings behind it against 2, so its average is the more settled of the two.
