Verdict
The clearest difference is ads: Simple GPS Speedometer at none against 全国路線地図's shown. Simple GPS Speedometer also leads on iOS requirement (15.1 vs 17.0). 全国路線地図's advantage is update cadence (every 2 weeks vs every 3 weeks). On price, in-app purchases and device support there is nothing between them.
