Sideload, not sketchy.

CueInbox is distributed via signed APK while we finalize the Play Store listing. Here's exactly what happens when you tap download — nothing hidden.

Step 01

Download the signed APK

Tap the download button. Your browser will ask to save a .apk file (~28 MB). It's signed with a stable developer key — hash below.

Step 02

Allow & install

Android will ask permission to install from this source — tap Allow. Then grant notification access, the same permission a Wear OS watch uses.

Watch it reason

AI that actually explains itself.

Used daily by people who hate notification overload.

We're small, so instead of vanity metrics here's what actually happens on the phones that installed CueInbox this week.

"Finally an app that just works across all my messaging apps. The AI correctly prioritized a critical Slack message over a meme from a friend."

"The privacy angle sold me immediately. Everything runs on-device — no API keys, no subscription, no data leaving my phone. This is how AI apps should be built."

"I was drowning in 330+ notifications a day. After a week with CueInbox I only read what the AI surfaces as 'Now'. Everything else waits. Game changer."

"The chain-of-thought trace is what sold me. I can literally see why it decided a message was 'Today' instead of 'Now'. Every other AI app is a black box."
