Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
