Verdict

The call

The clearest difference is in-app purchases: NDL at none against ScubaPlan's 4. NDL also leads on iOS requirement (12.0 vs 26.6). ScubaPlan's advantage is review sentiment (100% vs 67%) and update cadence (fortnightly vs every 5 months). On price, ads and device support there is nothing between them.
