Verdict
The clearest difference is in-app purchases: InkDown at none against Authenticator App's 16. InkDown also leads on ads (none vs shown) and update cadence (every 3 days vs every 3 weeks). Authenticator App's advantage is device support (4 vs 2) and iOS requirement (15.6 vs 26.0). On price there is nothing between them.
