Verdict
The clearest difference is in-app purchases: Satark at none against Seaside Buoy's 4. Satark also leads on ads (none vs shown). Seaside Buoy's advantage is update cadence (every 3 weeks vs every 3 months) and iOS requirement (11.0 vs 13.0). On price and device support there is nothing between them.
