Verdict
The clearest difference is in-app purchases: ESA Instruments at none against Lights Out Sailing's 2. ESA Instruments also leads on device support (3 vs 1). Lights Out Sailing's advantage is update cadence (every 5 weeks vs every 6 months). On price, ads and iOS requirement there is nothing between them.
