Verdict
The clearest difference is ads: スパルタ数取器 at none against Muscle Counter's shown. スパルタ数取器 also leads on iOS requirement (11.2 vs 15.0). Muscle Counter's advantage is update cadence (every 6 weeks vs every 16 months). On price, in-app purchases and device support there is nothing between them.
