Verdict
The clearest difference is ads: Code Buddy at none against Calculator +'s shown. Code Buddy also leads on iOS requirement (13.4 vs 16.4). Calculator +'s advantage is ratings volume (10K vs 6) and rating (4.6 vs 4.3). On price, update cadence, in-app purchases and monetization model 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. Calculator + sells 12 in-app purchases, starting at $4.99 per month and Code Buddy sells 3 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.
