Big Yellow Diary

Why keep a diary? My answer is, because some information may seem unimportant at the time, but later you might need it and forget it. For example, today I plan to visit a friend's house. Iβve been there before, but I just can't remember the exact address. Another example is, thereβs someone around me who said something, how can I judge if itβs true or not? One way is to compare it with what theyβve said before and see if there are any contradictions. Without a diary, there's no way to make such a comparison.

Verdict
The clearest difference is in-app purchases: LIFLOG at none against Big Yellow Diary's 1. LIFLOG also leads on iOS requirement (15.0 vs 17.0). Big Yellow Diary's advantage is update cadence (every 6 days vs every 3 weeks). On price, ads and device support there is nothing between them.
