Servers using 2FA will be supported in an upcoming release.

Verdict

The call

The clearest difference is in-app purchases: Thetis Authenticator at none against NextStats's 4. Thetis Authenticator also leads on review sentiment (60% vs 43%) and iOS requirement (13.0 vs 15.0). NextStats's advantage is update cadence (every 5 days vs every 9 months) and rating (3.7 vs 3.5). On price, ratings volume, ads and device support there is nothing between them.
