Verdict
The clearest difference is monetization model: Subscription Day. Calendar at free against Credit Card Tracker's freemium. Subscription Day. Calendar also leads on rating (4.8 vs 4.6). Credit Card Tracker's advantage is chart position (#117 vs unranked) and review sentiment (94% vs 83%). On price, ratings volume, update cadence and ads 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. Subscription Day. Calendar sells 5 one-off in-app purchases and Credit Card Tracker sells 3 in-app purchases, starting at $12.99 per month. Whichever you choose, the download price is not the number that matters.
Subscription Day. Calendar holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 19 and 47 respectively. Written reviews complicate that: 83% of Subscription Day. Calendar's written reviews are positive against 94% of Credit Card Tracker's, so the app with the better star average is not the one people write more warmly about.
Subscription Day. Calendar ships an update weekly, Credit Card Tracker fortnightly. Both last shipped on September 21, 2026.
