Verdict

The call

The clearest difference is ads: LeftRightDiary at none against Hera's shown. LeftRightDiary also leads on device support (3 vs 1) and iOS requirement (15.0 vs 18.6). Hera's advantage is update cadence (weekly vs monthly). On price and in-app purchases there is nothing between them.
