Verdict
The clearest difference is review sentiment: Citadel Team at 51% against My DIA's 0%. Citadel Team also leads on monetization model (free vs ad-supported) and device support (3 vs 1). My DIA's advantage is rating (4.4 vs 2.6) and update cadence (every 5 days vs every 2 months). On price, ads and in-app purchases 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. Neither carries in-app purchases, so what you see is what you pay.
My DIA holds the better App Store score, 4.4 against 2.6. That said, the two scores are not equally well evidenced: My DIA has 100 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 51% of Citadel Team's written reviews are positive against 0% of My DIA's, so the app with the better star average is not the one people write more warmly about.
Citadel Team ships an update every 2 months, My DIA every 5 days. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
