Verdict
The clearest difference is price: Juno at Free against MCAS Insight's $0.99. Juno also leads on ratings volume (11K vs 1) and chart position (#131 vs unranked). MCAS Insight's advantage is in-app purchases (none vs 11) and update cadence (every 2 days vs weekly). On rating, ads, device support and iOS requirement there is nothing between them.
