YES NOTE — A quiet sheet of paper, devoted to one thing: writing down your thoughts. No judgment, no rush. Write slowly, write true. ——————— We already have too many apps waving the "productivity" flag. YES NOTE goes the other way: it lets you sit down, write one line, and then do nothing. No schedules, no reminders, no complex formatting, no "daily completion rate", no achievements to unlock. It is just a sheet of paper. If you've ever read a line you desperately wanted to keep, if you simply want to set down a mood, a quote, or a thought that appeared out of nowhere — this was made for you. CORE FEATURES ———— · Titles are optional — the list shows the first line of your note · Tag every note your own way, and filter by tag from the bar up top · Long-press a note to turn it into one of 17 beautifully designed cards: beige book page, dawn gradient, movie poster, starry night, lamp-lit reading, classical book… each typeset in the LXGW WenKai typeface · Pin the notes that matter · Long-press for copy, share card, and delete · Quick tag filtering at the top of the list WHY THE TYPEFACE MATTERS —————— The whole app is set in the open-source LXGW WenKai typeface, born for long-form reading. When your thoughts are held by this type, even an ordinary sentence carries the quiet of paper. WHAT IT DOESN'T DO ————— · No account required, no user system · Notes stay on your device and sync only through your private iCloud · No third-party analytics, ads or tracking SDKs · Never touches contacts, location, microphone or other sensitive permissions · Never tries to turn note-taking into a streak All notes are stored locally on your device and synced only through your private iCloud. Export a backup before deleting the app. WHO IT'S FOR ———— · People who want one simple place to write things down · People who care about typography and visual quietness · People who often send a passage to a friend and want it to look like a piece of work · People tired of being hurried by their tools COMPATIBILITY ———— iOS 18.0 or later · iPhone, iPad & Mac · English and Chinese

Verdict
The clearest difference is update cadence: YES NOTE at fortnightly against Ruler's every 5 months. Ruler's advantage is iOS requirement (15.6 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.
