Verdict

The call

The clearest difference is in-app purchases: Re at none against LogZero's 3. Re also leads on iOS requirement (13.0 vs 16.4). LogZero's advantage is update cadence (every 5 days vs every 32 months) and ratings volume (8 vs 1). On price, rating, ads and device support there is nothing between them.
