Yosuga, the iOS app that turns saving into a promise to your future self, is now available on the App Store. Entrust something you care about, and a quiet word arrives on the promised day so you can see it through — reading, watching, going, buying, or making. The promise loop (entrust → word → today's promises → fulfill) is free to use.
See the product page for the full details. We'll keep refining the app so it can hand your promises to your future self, quietly and surely.
