Kizzuna App · A Guided Tour

The app that helps
you look up.

Here's the idea — the answer isn't just taking your phone away. It's what you get back when you put it down. Kizzuna helps you reclaim the little pockets of time that are actually yours. No harsh blocks, no shame. Just a streak worth keeping, a grove that grows as you go, and an honest look at where your hours really went.

Common Questions

Answers to the
things people ask.

Kizzuna is an iPhone app that helps you spend less time on your phone — but really, it's about what you get back when you do. Instead of harsh blocks, it turns putting the phone down into something quietly worth doing: a streak worth keeping, a grove that grows as you go, and an honest look at where your hours actually went.
Download Kizzuna from the App Store, open it, and sign in with Apple. It'll ask for Screen Time permission — that's what lets Kizzuna measure your usage, right there on your device, so it can show you your progress. Grant that, and you're in.
Kizzuna is built on Apple's Screen Time tools. It needs that permission to see how much you're using your phone and the apps you choose to track. Without it, there's no way to show your daily numbers, your streak, or your insights.
Yes — and this one really matters. Your usage stays on your phone. No email list, no ad tracking, no selling your data. Your time is yours.
Every day you spend under your personal baseline builds your streak and grows your grove a little. Over time you unlock seals — small milestones like First Light, Seven Days, and Moonlit — so you can actually watch your progress take shape.
The Darkroom is where you pick the apps that pull hardest. Open one, and Kizzuna asks for a single breath first — a small pause between the impulse and the scroll. It's not a wall; it's a second to decide whether you really meant to open it. Prefer to just watch your habits? You can track an app for insights without any pause at all.
Because everything lives on your phone, deleting the Kizzuna app takes its data with it. Any other questions about your data — just reach out and we'll help.
