Verdict
The clearest difference is in-app purchases: SolverApp at none against Doubble's 27. SolverApp also leads on ads (none vs shown) and iOS requirement (12.0 vs 15.6). Doubble's advantage is update cadence (every 6 days vs every 2 months). On price and device support there is nothing between them.
