Verdict
The clearest difference is in-app purchases: MemDatStack at none against Yaktraks's 1. MemDatStack also leads on update cadence (every 9 days vs every 3 months) and rating (5.0 vs 4.7). Yaktraks's advantage is ratings volume (18 vs 2) and iOS requirement (16.6 vs 18.6). On price, ads and device support there is nothing between them.
