Verdict

The call

The clearest difference is review sentiment: AltosUI at 100% against Navi's 29%. AltosUI also leads on rating (4.8 vs 4.4) and iOS requirement (12.0 vs 15.0). Navi's advantage is price (Free vs $19.99) and ratings volume (1K vs 4). On ads, in-app purchases and device support there is nothing between them.
