Verdict

The call

The clearest difference is in-app purchases: Dr Diary at none against GasBook's 3. Dr Diary also leads on device support (3 vs 1) and iOS requirement (12.0.0 vs 26.0). GasBook's advantage is review sentiment (50% vs 21%) and update cadence (monthly vs every 3 months). On price and ads there is nothing between them.
