Verdict
The clearest difference is in-app purchases: PulmTools at none against CredBook's 2. PulmTools also leads on ratings volume (8 vs 1). CredBook's advantage is update cadence (every 2 days vs every 5 days) and iOS requirement (15.1 vs 18.5). On price, rating, ads and device support there is nothing between them.
