Verdict
The clearest difference is in-app purchases: IsI Tanktagebuch at none against SpoolManager's 3. IsI Tanktagebuch also leads on iOS requirement (16.4 vs 18.0). SpoolManager's advantage is update cadence (fortnightly vs every 39 months). On price, ads and device support there is nothing between them.
