Verdict

The call

The clearest difference is price: Sakutrain at Free against ArcEmu's $1.99. Sakutrain also leads on update cadence (every 4 days vs every 2 weeks) and iOS requirement (11.0 vs 15.5). ArcEmu's advantage is chart position (#183 vs unranked) and device support (5 vs 2). On ads and in-app purchases there is nothing between them.
