YOSUGA
What you entrust comes back to you when the time is right.To turn someday into today.
We're getting it ready for iPhone. Just a little longer until release.
Find something you care about? Entrust it. That's all.
The next day, a word arrives. “When shall we promise this?”
You choose the day.
When the promised day comes, another word arrives. “You were going to read that article.”
Once you've read it, fulfill the promise. Not yet? Postpone it. Changed your mind? Let it go.
— After that, you can forget. Yosuga remembers.
THE PROMISE LOOP
Yosuga isn't a box for hoarding information. It turns the promises you've entrusted into something you can keep, and hands them back to your future self, for certain.
Hand one URL to your future self from the iOS share sheet. The moment asks for almost nothing — just choose how you'll meet it again. The title and thumbnail are filled in for you, and you can settle on the promised day later, in calm.
When the promised day comes, we let you know, quietly. “You were going to watch this.” Fulfill, postpone, or let go — the choice is yours. For things you keep postponing, we gently add: “Shall we let this go?”
The home screen holds no long lists. It quietly shows only what has come to meet you today. A promise drawing near glows as a warm golden star. On an empty day, it simply says, “No promises today.”
Read, watch, go, buy, make — only by seeing it through does it become worth something. Each time you fulfill one, the sky grows a little brighter.
Beyond waiting for word, you can go to everything you've entrusted whenever you wish. They're ordered by the time of each promise. Filter by how you'll meet it, and meet it on the spot — even before the promised day.
Even past the promised day, there's nothing to worry about. In the coral of dusk, it just lets you know, quietly — so the small guilt of not having looked never piles up.
MEET IT, DEEPLY — Pro
A quiet set of tools to carry each promise to the end. The promise loop is always free. Depth and comfort come with Pro, available as monthly or yearly subscriptions, or as a one-time purchase.
A quiet reading view with just the article text. Keep the text in hand, so you can pick up where you left off even with no signal.
It reads the article aloud, so you can take it in by ear — on a walk, between chores. Even when your hands are full, you can keep your promise.
This week's count fulfilled, your completion rate, average days to fulfill, a breakdown by how you'll meet it. The promises you've kept quietly add up. We don't measure by how much you saved — what matters is whether you saw it through.
Even with notifications off, you're fine. A small window on your Home Screen shows today's promises at a glance, quietly.
QUIET BY DESIGN
No servers of our own, no account to create. What you entrust stays, as a rule, on your device.
No behavioural analytics, no ad networks — none at all. Every word is a local notification on your device.
Sync across your iPhone, iPad, and Mac with your own iCloud. We never hold your data.
Pro — monthly / yearly subscription or one-time purchase
Saving is unlimited and free. The promise loop (entrust → word → today's promises → fulfill) is free forever, too. We never charge by how much you save.
