Verdict
The clearest difference is monetization model: DieselCalcs at free against Mezzi Wealth's subscription. DieselCalcs also leads on rating (5.0 vs 4.7). Mezzi Wealth's advantage is update cadence (weekly vs every 2 months) and ratings volume (116 vs 3). On price, ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Mezzi Wealth sells 13 in-app purchases, starting at $12.00 per month and DieselCalcs sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
DieselCalcs holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Mezzi Wealth has 116 ratings behind it against 3, so its average is the more settled of the two.
