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.
myDATAapp holds the better App Store score, 2.5 against 1.2. That said, the two scores are not equally well evidenced: NBG Authenticator has 12 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 1% of NBG Authenticator's written reviews are positive against 0% of myDATAapp's, so the app with the better star average is not the one people write more warmly about.
NBG Authenticator ships an update every 2 weeks, myDATAapp fortnightly. The most recent releases landed on June 11, 2026 and September 19, 2026 respectively.
