Verdict

The call

Weblio英語辞書 and スマート辞書 both sit at 4.5 stars, but that hides the real split: 57% of スマート辞書's written reviews are positive against 42% of Weblio英語辞書's. スマート辞書 also leads on update cadence (every 9 days vs every 3 weeks). Weblio英語辞書's advantage is ratings volume (174 vs 14) and device support (3 vs 1). On price, rating, ads and in-app purchases there is nothing between them.
