Verdict

The call

The clearest difference is rating: Deep Whois at 4.5 against Mobile OTP Authenticator's 3.5. Deep Whois also leads on ratings volume (172 vs 2) and iOS requirement (13.4 vs 15.6). Mobile OTP Authenticator's advantage is in-app purchases (none vs 4) and ads (none vs shown). On price, update cadence and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Deep Whois holds the better App Store score, 4.5 against 3.5. That said, the two scores are not equally well evidenced: Deep Whois has 172 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 85% of Deep Whois's written reviews are positive against 100% of Mobile OTP Authenticator's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Deep Whois ships an update every 4 months, Mobile OTP Authenticator every 8 months. Both last shipped on September 28, 2026.
