Verdict
The clearest difference is in-app purchases: Void Hopper at none against Join Numbers's 1. Void Hopper also leads on ads (none vs shown) and rating (5.0 vs 4.6). Join Numbers's advantage is ratings volume (19K vs 1) and iOS requirement (13.0 vs 15.0). On price, update cadence and device support there is nothing between them.
