Lab / Kokoro 1.2.1 · Next version
Hana answers from
your real numbers.
Kokoro is an on-device wellness companion for iPhone and Apple Watch. The next version makes it free, syncs your reflections, check-ins, journal and medical vault through your own iCloud with end-to-end encryption, and lets Hana look things up and help you log, always asking before she saves.
Try it: ask Hana
She never guesses a number, and she asks before she saves.
Most questions about your data are answered by rules from your real readings before the language model is involved, and if there is no reading, Hana says so instead of inventing one. When she wants to save something, you get a card, and nothing changes until you tap Save.
- Nothing saved yet.
Save something to see it sealed.
Every record is checked when it's read back.
A simulation with a sample week of data; nothing leaves your browser. The sealing uses your browser's Web Crypto with a key made for this page, to show the idea: in Kokoro, entries are encrypted on your device with a key only your devices hold, and a changed record is flagged instead of being trusted.
What's new in 1.2.1
Still completely private, now on all your devices.
Free
Every feature unlocked for everyone, with no subscriptions and no in-app purchases.
Private iCloud sync
Reflections, check-ins, journal, schedule and the medical vault sync through your own private iCloud, encrypted end to end. Nothing is stored on any server of ours.
A fresh look
A new app icon and a calmer, more consistent design across Home, Time, Profile and your conversations with Hana.
Tamper detection
An audit trail keeps your records honest and flags any unexpected change.
A smarter Hana
She can look things up in your real data and help you log a check-in, set a word for the day or jot a note, and she always asks first.
Bring your own AI
Optionally connect your own OpenAI, Anthropic or Google key for richer conversations. Off by default.
In the lab: this page describes Kokoro 1.2.1, which is not on the App Store yet. Kokoro is a wellness companion, not a medical device, and gives no medical advice.
