Verdict

The call

The clearest difference is ratings volume: ideaShell at 609 against Komoriba's 1. ideaShell also leads on device support (4 vs 2) and iOS requirement (15.0 vs 18.6). Komoriba's advantage is rating (5.0 vs 4.7) and update cadence (every 5 days vs every 10 days). On price, review sentiment, ads and in-app purchases there is nothing between them.
