Verdict

The call

The clearest difference is in-app purchases: Fortress SOS at none against Deadline's 2. Fortress SOS also leads on iOS requirement (11.0 vs 26.0). Deadline's advantage is update cadence (every 2 weeks vs every 2 months). On price, ads and device support there is nothing between them.
