Verdict
The clearest difference is price: DuoLogic at Free against A Long Time's $0.99. DuoLogic also leads on rating (5.0 vs 3.9) and update cadence (every 11 days vs monthly). A Long Time's advantage is ratings volume (13 vs 1) and iOS requirement (15.6 vs 17.6). On ads, in-app purchases and device support there is nothing between them.
