Verdict
The clearest difference is price: Lucid Poker Trainer at Free against ShellRef's $0.99. Lucid Poker Trainer also leads on ratings volume (19 vs 1) and iOS requirement (13.0 vs 17.6). ShellRef's advantage is rating (5.0 vs 4.0) and in-app purchases (none vs 4). On update cadence, ads and device support there is nothing between them.
