Bloo

I wanted an app for my Hyundai that felt like Google built it. So I made one.

Bloo is a third-party Android app for controlling Hyundai, Genesis, and Kia vehicles through their US telematics services. Built with Jetpack Compose and Material 3 Expressive for phone, foldable, tablet, and Wear OS. No simulated data -- every screen talks to live servers.

Supported brands

Brand	Service	Login	Gen5W (pre-CCNC)	CCNC (gen 3+, 2023+)
Hyundai	Blue Link	Email + PIN	No trips, limited climate	All features
Genesis	Genesis Connected	Email + PIN	No trips, limited climate	All features
Kia	Kia Connect	OTP only	All features	All features (no gen field)

• Gen5W (pre-2023, generation code 1-2): The older head unit. Trip history is not available through the API. Climate controls are limited to temperature and defrost only. Seat heat and custom duration values are rejected by the server.
• CCNC (2023+, generation code 3+, Connected Car Navigation Cockpit): The newer head unit. Full API support for all features including trip history, seat heat, and climate duration.
• Kia: Does not expose the head unit generation, so all features work across all model years. One-time code sign-in instead of PIN.

Multiple brands can be signed in at the same time. Credentials are stored encrypted on-device.

Building

./gradlew assembleDebug

APKs are output to app/build/outputs/apk/ and wear/build/outputs/apk/.

Requires Android Studio Meerkat or newer (AGP 9.1, Kotlin 2.2.20).

Installing

Every push publishes a rolling GitHub Release tagged build-<run number> with the phone (Bloo.apk) and watch (Bloo-Wear.apk) APKs attached as direct downloads -- plain public files, no GitHub sign-in and no zip/unzip step.

To install:

1. Download Bloo.apk (and Bloo-Wear.apk for the watch) from the latest release
2. Open the downloaded file from your notification shade or Downloads app
3. If Android shows "Blocked by Play Protect", tap "More details", then "Install anyway" and confirm with your biometrics or device password

The warning appears because Bloo is not signed with Google Play Store keys. I cannot publish on the Play Store because it costs money I do not have, and Hyundai would not approve an unofficial app on their platform. The app is safe, open source, and does not collect any data. All credentials are stored encrypted on-device.

Once installed, updates are entirely automatic and need no configuration: the app checks on cold start and every pull-to-refresh, plus a periodic background check even while it's closed, surfacing a tile that downloads and hands the APK straight to the system installer -- the steps above are only needed for the very first install. The watch checks and installs its own updates the same way, independently of the phone.

Architecture

Module	Purpose
:shared	API clients (BlueLinkApi, KiaUsaApi), Models, SessionStore, WearSync protocol
:app	Phone UI, widget (Glance), Quick Settings tiles, Wear bridge
:wear	Wear OS app, tiles (ProtoLayout), complications, data layer
:uicommon	Shared compose components (slider, segmented control, text animations)

Auth tokens are refreshed automatically on 401/403. A second failure returns to the sign-in screen.
