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.

Vismory helps you keep passing information and memories from slipping away. Every day, useful ideas and scenes move past quickly: a detail in a video, a reference in a feed, a screenshot you want to revisit, a photo from daily life, or something shared from another app. Saving the image is easy. Remembering why it mattered later is the hard part. Vismory turns those moments into lightweight visual notes. Start from a photo, screenshot, shared item, text, URL, or clipboard content, then add a short note so the reason stays with what you saved. What you can do with Vismory: - Save photos and screenshots with short notes - Start a note from shared content or clipboard text - Keep ideas, references, and everyday scenes before they disappear - Review saved items in an image grid, summary list, or calendar view - Find what you saved with clues such as note text, tags, dates, places, sources, and capture details when available Vismory is made for the space between a full note and a forgotten screenshot. It gives you a quick way to save what caught your eye and enough context to understand it later.

Verdict
The clearest difference is ads: Big Yellow Diary at none against Vismory's shown. Vismory's advantage is iOS requirement (15.1 vs 17.0). On price, update cadence, in-app purchases and device support there is nothing between them.
