Verdict

The call

The clearest difference is ads: Kryptxt at none against iSecure's shown. Kryptxt also leads on iOS requirement (12.0 vs 17.0). iSecure's advantage is update cadence (every 2 days vs every 93 months). On price, in-app purchases, monetization model and device support there is nothing between them.
