Verdict

The call

The clearest difference is ads: 楽爺々占 at none against Radar Chart's shown. 楽爺々占 also leads on update cadence (every 3 weeks vs every 11 months). Radar Chart's advantage is device support (3 vs 1) and iOS requirement (14.0 vs 16.0). On price and in-app purchases there is nothing between them.
