Verdict
The clearest difference is in-app purchases: Iso Link at none against Eulerian's 9. Iso Link also leads on update cadence (every 2 weeks vs every 3 weeks) and iOS requirement (15.0 vs 17.0). Eulerian's advantage is ads (none vs shown). On price and device support there is nothing between them.
