Verdict
The clearest difference is in-app purchases: RegEspresso at none against ClipStackX's 1. RegEspresso also leads on ads (none vs shown) and iOS requirement (8.0 vs 15.0). ClipStackX's advantage is update cadence (every 3 days vs every 8 months). On price and device support there is nothing between them.
