About

TRZR Journal

Features
Read full description

TRZR is an anti-social network โ€” a social feed with no one else in it. We spend hours scrolling other people's thoughts, yet rarely capture our own. TRZR flips that habit. The interface feels like Threads or X โ€” a familiar, frictionless feed โ€” but every entry in that feed is yours. Past thoughts, observations, links you wanted to remember, places you visited. Your timeline, exclusively. โ–  Zero friction to write Tap +, type what's on your mind, done. No titles, no prompts, no "dear diary." TRZR is designed for the one-line thought at 7am and the three-paragraph realization at midnight. Both belong here. โ–  Structure your own story Tag posts and assign them to Themes โ€” "Work Notes," "Reading Log," "Random Thoughts." Themes turn a stream of entries into chapters of a personal narrative. Links are saved with full OGP previews. Location is optional but preserved when you want it. Your record, with context. โ–  Context that comes back when you need it The people, places, weather, and micro-seasons of a day. Names you wrote with @ become Person entries โ€” rename one and every past mention updates with it. Pick places from the map and save them as "Home" or your favorite cafรฉ. The day's weather and the 72 micro-seasons of the Japanese year quietly ride along. The air of the moment comes back when you find that entry again. โ–  Make it yours Give each Theme a color from a curated palette of 8 traditional Japanese hues. Choose body fonts from 8 options (4 Japanese, 4 Latin) and dial in the size. Re-reading should feel as good as writing. โ–  Safe to leave alone Lock with Face ID or Touch ID, and TRZR fades the body behind frosted glass in the app switcher. Knowing your entries are safe is the prerequisite for actually writing them down. โ–  Privacy by architecture TRZR stores data in iCloud only. No proprietary server. No third-party data transmission. Your entries live on your devices and Apple's infrastructure โ€” nowhere else. This isn't a privacy policy promise; it's how the app is built. โ–  Search the way you think Full-text keyword search plus tag filtering, combinable with AND logic. Find the note you wrote about that book three months ago in seconds. "Where did I write that?" โ€” solved. โ€” The name TRZR (pronounced "tsure-zure") is taken from Tsurezuregusa, a 14th-century Japanese essay collection by Yoshida Kenkล, which opens: "With nothing else to do, I sit before my inkstone and jot down whatever drifts into my mindโ€ฆ" That impulse โ€” writing because you feel like it, not because you have to โ€” is what TRZR is for. Add a photo when you want one, or leave it text. Keeping the friction low is what keeps you writing.
