Verdict
The clearest difference is price: SuperSummary at Free against ShellRef's $0.99. SuperSummary also leads on ratings volume (2.3K vs 1) and iOS requirement (15.0 vs 17.6). ShellRef's advantage is in-app purchases (none vs 6). On rating, update cadence, ads and device support there is nothing between them.
