Verdict
The clearest difference is review sentiment: 3Stone AI at 100% against iPostal1's 17%. 3Stone AI also leads on rating (5.0 vs 3.3) and update cadence (every 2 days vs every 3 weeks). iPostal1's advantage is in-app purchases (none vs 6) and ratings volume (1.1K vs 1). On price, ads and device support there is nothing between them.
