Verdict
The clearest difference is price: Charts+ at Free against V Speed Calculator's $0.99. Charts+ also leads on update cadence (every 5 months vs every 14 months) and ratings volume (13 vs 2). V Speed Calculator's advantage is rating (3.0 vs 1.3) and device support (3 vs 1). On ads, in-app purchases and iOS requirement there is nothing between them.
