Verdict
The clearest difference is in-app purchases: eDMR at none against iChecker's 1. eDMR also leads on ads (none vs shown) and update cadence (every 4 days vs every 2 months). iChecker's advantage is device support (3 vs 1) and iOS requirement (9.0 vs 17.6). On price there is nothing between them.
