Verdict

The call

The clearest difference is in-app purchases: UAP SIGHTER at none against Ulysses's 7. UAP SIGHTER also leads on update cadence (every 2 days vs every 3 weeks) and iOS requirement (13.0 vs 26.0). Ulysses's advantage is rating (4.6 vs 4.2) and ratings volume (2.2K vs 6). On price, ads and device support there is nothing between them.
