Quick answers.

Installing

Android says the app is blocked or “unsafe”.

Kai isn’t on the Play Store yet, so Android asks once whether your browser may install apps. Allow it for this one install. Play Protect may scan the app the first time; that’s normal for apps installed from a website.

“App not installed” or it won’t open.

Kai needs Android 8 or newer on a 64-bit phone. If you had an older test build signed differently, uninstall it first, then install the new APK.

I don’t have a beta key.

Request one on the download page. You get a confirmation email right away, and your personal key when your spot opens.

My key doesn’t work.

Keys look like KAI-XXXX-XXXX and aren’t case-sensitive. Copy it straight from the email. Still stuck? Send us a help request with the email you applied with.

Voice and logging

Kai misheard me.

Say “undo” or “change that to 70 kilos”. Speaking a little slower helps in a loud gym, and you can switch the speech language in Settings → Voice (English, Filipino and more).

Can I log without talking?

Yes. Type in the chat, scan a barcode, or snap your plate. Everything you can say, you can type.

The calorie estimate for my meal looks wrong.

Tell Kai the portion (“it was one cup of rice, not two”) and it recalculates. Photo estimates are a starting point; correcting them teaches nothing to anyone else and costs nothing.

Watch and Health Connect

My Galaxy Watch data doesn’t show up.

In Samsung Health → Settings → Health Connect, turn sync on. Then in Kai: Settings → Watch → Sync now. On Android 13 and older, install Health Connect from the Play Store first.

Which watches work?

Any watch whose app writes to Health Connect: Galaxy Watch (via Samsung Health), Pixel Watch (Fitbit), Garmin, Amazfit, Xiaomi and more. On iPhone, Kai reads Apple Health.

Calories burned look low or high.

Kai shows exactly what your watch reports. Wearing it snug, with heart rate on, makes the estimate better.

Account and data

How do I delete everything?

In the app: Settings → Delete my Kai data. It permanently removes your logs, photos, plan and conversations. See the Privacy page for what’s kept and why.

I changed phones.

Install Kai on the new phone and sign in with the same Google account. Everything is in your account.

Does the website show my data?
