Verdict
The clearest difference is in-app purchases: FSWizard at none against iMI's 5. FSWizard also leads on ratings volume (47 vs 3) and iOS requirement (11.0 vs 18.6). iMI's advantage is update cadence (every 4 days vs monthly) and rating (5.0 vs 4.6). On price, ads and device support there is nothing between them.
