Verdict

The call

The clearest difference is in-app purchases: Milthm at none against Project's 18. Milthm also leads on ads (none vs shown) and rating (4.9 vs 4.6). Project's advantage is ratings volume (1.5K vs 275) and iOS requirement (12.0 vs 15.0). On price, update cadence and device support there is nothing between them.
