Verdict
The clearest difference is in-app purchases: InterviewOS at none against AI Interview's 2. InterviewOS also leads on ads (none vs shown) and update cadence (every 3 days vs every 2 weeks). AI Interview's advantage is iOS requirement (17.0 vs 26.0). On price and device support there is nothing between them.
