Things to keep, things to do — one home for your everyday.
Shimau is one place for the scattered stuff of daily life: notes, to-dos, links, and photos. Videos from social media, half-read articles, screenshots, passing thoughts — just toss them in. No folders. No tagging. No filing.
◆ Zero-effort saving
Pick "Shimau" in the share menu — you don't even need to open the app. For quick thoughts, tap the center "+". Shimau tells links from notes automatically as you type.
◆ AI understands what you saved
Links and screenshots get automatic summaries and tags. Screenshots become searchable through on-device text recognition. Notes you write yourself are never sent to AI.
◆ Find things the way you remember them
"That ramen video from last week" — search in your own words and it shows up.
◆ To-dos live on sticky notes
Stick a note on a box, peel it off when it's done. The small satisfaction of an empty box keeps you going. Checklist notes open in a focused to-do mode.
◆ A one-line daily journal
Once a day, log your mood and a single line — and look back with a little bear at your side. History, calendar, and stats grow the longer you keep going.
◆ Make it your own
Choose a theme — Cozy or Lovely Pink, plus Calm Blue and Mono with Pro — and dress up box covers with theme art, photos, or colors and emoji.
◆ Only deadlines, gently
When a saved booking or coupon has a date, Shimau offers a reminder. Choose how it speaks up: quiet, standard, or strong. No other notifications, ever.
◆ Private by design
What you save stays on your device. Nothing is stored on our servers or used to train AI. If you turn on iCloud sync, it is kept in your own iCloud.
Things to keep, things to do, and how today felt — all in one place you'll always find again. That's Shimau.

Introducing Shimau Pro.
・iCloud sync and backup — nothing you have put away is lost when you change or break a device, and your iPhone and iPad hold the same things
・Lock with Face ID — Face ID or your device passcode is asked for when you open the app
・More themes — "Calm Blue" and "Mono" have been added
$1.99/month or $14.99/year. Everything you had before stays free.
Shimau now supports iPad.
・On a wide screen the list and its contents sit side by side, so you can read through boxes, records and settings without going back and forth
・Narrow the window with Split View or Slide Over and you will not lose what you were reading
・You can now use an external keyboard
・On iPhone in landscape, text is kept at a comfortable reading width
You can now back up everything (Settings → Data).
・Photos, PDFs, boxes and sticky notes all go into a single file
・You can restore from that backup. Nothing you have now is removed
If you were on 3.0, here is what we fixed.
・After updating the app, photos and PDFs sometimes did not sync to iCloud, and were missing from backups too. We are sorry: you could have believed you had a backup when you did not
・A photo set as a box cover could disappear after updating the app
・On iPad, "Back up everything" and "Export data" sometimes did nothing when tapped
・Syncing could stay unfinished, or take a very long time. Dozens of items now finish in seconds
・Settings now has "Sync everything again", for when something has not reached your other devices
・In mainland China, prices sometimes did not load and Pro could not be purchased. We are sorry
Let us know anything you notice from "Send feedback" in Settings.
