Verdict
CharacterDiagram and Radar Chart both sit at 4.0 stars, but that hides the real split: 72% of Radar Chart's written reviews are positive against 33% of CharacterDiagram's. Radar Chart also leads on ratings volume (255 vs 2). CharacterDiagram's advantage is ads (none vs shown) and update cadence (every 3 months vs every 11 months). On price, rating, in-app purchases and device support there is nothing between them.
